Steel structure industry also need to restructure?Stage quick release and steel production capacity in under the background of overall demand, oversupply of has come, the data suggest that steel demand has fallen from fears become a reality. Expansion of large-scale iron and steel industry in recent years, has seriously broken the balance between supply and demand situation, the change of production pattern is imperative, it all contributed to the emergence of the restructuring, corporate restructuring in 2005 called especially fierce, so it seems that the restructuring of the steel industry is the fact that iron nail nails. Related to this industry is flourishing development of Steel Structure Warehouse, but the scale of the enterprise and management are unsatisfactory. And supporting industries, such as bolts, containment system industry, whether also need to restructure, to match its development? The high strength bolt, for example to discuss first.
Developing rapidly in recent years, steel structure, at the same time, led high strength bolts in the related industry prosperity, and great changes have taken place in enterprise and product structure, high strength fasteners production enterprises increased, market competition is very fierce, driving the enterprise to increase the quality of our products and develop new products, new technologies, new processes, new equipment, new material, reduce the production cost to occupy the market, improve the industry overall quality level, but from the product quality supervision and spot check result, sampling percent of pass has for years been hovering around 60% - 80%, reflecting the more concentrated the quality problems.
First in the scale, quality, scale, brand enterprise less, nearly two years, zhejiang zane, quickly occupied the national major project of the market. Due to the particularity of the industry, investment in a firm's capital requirement is not high, the cottage enterprises, technology level cannot meet the requirements. Under the fierce competition in the level of phased out a batch of qualified enterprises, through the quality supervision and spot check, raise awareness of the law of business operators and consumers, increase the intensity of law enforcement, management quality work in accordance with the law, promote implement current national standard, make the enterprise really understand the standard requirements, in strict accordance with the standards organization production, and encourage the use of units as far as possible in the design of the methods of current standards, greatly improved the quality of the products.
In marketing management, management experience, management means, management personnel have taken is the traditional pattern, the salesman to run market, engineering, these are challenges; Market management, price management, promotion management are at medium level. Currently, fastener sales market is relatively chaos, some distribution unit is concerned with the immediate interests, do not attach importance to product quality, blindly rely on lower product prices for the market, even distribution of fake and shoddy products, become a breeding hotbed of inferior performance, serious can cause an accident.
In terms of sales channels: so far, most of the enterprise is a kind of "feeling" mode, operating in dribs and drabs, and inconvenient transportation, there are a lot of limitations. Recently, 16 cities of Yangtze river delta logistics Shinkansen "spare parts" has officially launched, is expected to completed in 3 years. Shinkansen "is responsible for the spare parts logistics project of Shanghai xupu standard parts co., LTD., chairman of Zheng Jinguo said, the current domestic standard product ratio of market circulation is not harmonious, can the first time with the Yangtze river delta seamless docking, advanced manufacturing industry and the major project is an urgent subject that standard parts industry development and upgrade. The company has built a ton of stereo logistics warehouse, become domestic standard parts industry the most complete specifications in manufacturing output and headquarters, and "spare parts logistics Shinkansen" would significantly reduce logistics cost. The "precision manufacturing, quick delivery" as the characteristics of the new spare parts logistics mode is the first in the domestic standard parts industry, develop the components of net sales, smooth sales channels for the future laid a solid foundation.
In the present this kind of form, whether can restructure reform, can bring the entire industry development after the reform, we can from two aspects to consider. There are two advantages of restructuring reform:
1, a large-scale enterprise, which is beneficial to overall management, scientific research and innovation ability will be greatly improved, the product research and development speed also have great improvement.
2, to overcome the disorder of market competition situation, can effectively maintain the stable development of the market.
, of course, the emergence and development of any new things are always two sides to everything, there are advantages and disadvantages of the main disadvantages are:
oor coordination between 1, after the restructuring of enterprises, the contradiction is more, maintain a MianHeXinBuHe new situation between businesses, is not conducive to work.
2, after the restructuring of enterprise scale is too big, bloated, moreover, some enterprises are not suitable for unified management, hard to avoid is not comprehensive.
Industry restructuring, therefore, although could bring more rapid development and prosperity, but throughout the entire industry, steel industry has been developing, not enough mature and perfect, there are problems, is still the current phase of the main contradictions, that is to say, no matter in industry background, or on the enterprise scale, the restructuring of the current steel structure industry base are woefully inadequate. Steel Structure Warehouse http://www.jingtabuilding.com/steel-structure-workshop.html industry restructuring is the only way for the development of China's steel structure industry revitalization, although restructuring now exist many difficulties, but every effort to let we took a step to success, let us together look forward to that day coming soon.
The bird's nest stadium will into the key phase of the first piece of steel structure

The steel structure housing industrialization business opportunities to attract
The steel structure housing industrialization business opportunities to attract "eyeball"How to reduce energy consumption in residential construction and use process, achieve energy conservation and environmental protection, is the chief problem of the current residential construction in our country.Steel Structure Warehouse http://www.jingtabuilding.com/steel-structure-workshop.html housingSystem because of easy to realize industrialized production, standardization production. Belongs to the green environmental protection building. Renewable reuse, accord with the strategy of sustainable development, more and more cause the attention of the construction industry. Countries in recent years toSteel structure housingAttention and support will be significantly increased, the related technical standard formulation work also in gradually into the track. Related to aspects such as the ministry of construction also launched a 36 items & other; Steel structure housing system and the key technology & throughout; Research topic for iron and steel enterprises in the product development research, puts forward a new research direction. These signals show that the steel structure housing industrialization of spring has come.
Industry guide the demand increases
Steel structure industry driven by the rapid development of China's steel demand for steel structure, constructed the huge potential for China's steel industry development platform. In recent years, the domestic market of steel used in construction steel structure increasing annually with 500000 tons of speed up. In 2005, construction steel structure steel demand is expected to reach 14 million tons, and in the next few years, may increase to 18 million tons. Compared with the developed countries in the world, the steel structure industry in China has a larger development space and the application field, residential construction is gradually becoming the pillar industry of national economy, ten years is expected to 5.6 billion square meters of new housing, steel structure residential building will be 5.6 million a year?? 28 million square meters. Compared with the traditional structure, steel structure residence in use function, design, construction, and comprehensive economic has obvious superiority.
China clearly pointed out that the development of residential steel used in key areas and key technology refers to the building of cold, hot-rolled steel bar and connection technology, steel welding nets and construction steel structure production and installation technology.
At present, in the production of construction materials and applications, mainly there are advantages of structural steel varieties (such as quality, thick plate, structural steel welding, etc.), high strength steel application proportion is low, the economic profile hot-rolled H section steel and cold bending profiles are used much, less problems such as product specifications. Industry experts put forward, and strive to improve the quality of structural steel, varieties, properties and application level, in 2010 the national steel structure steel weight of the year will reach 4% 5% of steel production, varieties required to high value-added step by step. Mainly embodied in the following aspects:
special thick plate steel structures of tall building (the shock can be germinated, Z to) all the localization, structure with high strength low alloy steel varieties increased (such as welding of structural steel and low bend reinforcement steel and refractory steel, etc.). Application proportion increased.
hot rolled H section steel domestic application all localization, and developed a thin wall of hot-rolled h-beam produced by controlled rolling technology and strength, good low temperature impact toughness of star h-beam and other new products.
- production and supply of high strength cold-formed profiles, development and production of new varieties for low-rise and light steel structure, such as hollow flange beam, corrugated web beam, large cross-section ribbed C payments, such as the recent should be as soon as possible production supply oblique edge Z steel, dovetail pressure plate.
- vigorously development, the production performance good generalization and commercialization of steel structure products and components, such as series of light steel structure housing, honeycomb, underground engineering steel support beam and T section steel truss and so on.
Should popularize multi-storey light steel structure housing
The personage inside course of study thinks, the current domestic. Although layers, including a handful of high-level steel structure housing has been built, but basically all use steel frame, pouring concrete, from the strict sense is not a real steel structure housing, no good play to the superiority of steel structure housing, even the sound insulation, waterproof and so on basic problems are unsolved. Therefore, the new residential building system research and development and the introduction of good performance has become the top priority.
Multi-storey light steel structure residence is a new type of energy-saving and ground-saving residential system. Light steel structure residence has excellent energy saving performance. This kind of structure with light weight, seismic, heat preservation, heat insulation performance is good, dry operation, water-saving effect is remarkable, short time limit, low cost advantages, more and more known by people. Abroad by using this system to build a small house for nearly 30 years of history, in recent years in the United States, Canada and other countries has been developing rapidly. But in our country, research and development and the introduction of multilayered cold bending thin-wall steel housing system, stimulate the circulation of steel is used to carry out the & other; Throughout the development of circular economy and build a conservation-minded society &; A specific policy measures. At present, developed by hangxiao high-rise steel structure residential building system and related products have been listed as the ministry of construction to promote projects, and has been applied in the project under construction in wuhan century home. The project will build 12 24 layer of high-rise residential buildings, is the home of the first true sense of green high-rise steel structure residential building projects.
Construction ministry concerned expert analysis, using the superiority of multi-storey light steel housing system mainly includes: the first is land. On the one hand, multi-storey light steel structure housing adopts composite wall, the main structure of cold bending thin-wall steel keel, heat preservation material such as cotton, plasterboard, can completely replace the current our country is still in extensive use of solid clay brick, can reduce the destruction of farmland by the brick; On the other hand, can effective use of land resources, increase the residential use area, multi-storey light steel structure housing area less than masonry structure and concrete structure, can increase effective use area of about 6%. Second is energy conservation. If using light steel structure construction of multi-storey residential, according to the European and American standards, residential real annual energy consumption can be reduced to 6 liter/square meters, equivalent to about BiaoMei 8.75 kg/square meters, can save BiaoMei 17.5 kg/m2. The third is water. Light steel structure is adopted during the construction of do homework, in addition to the foundation construction in water, no water is used in the construction site is almost. So, construction of multi-storey light steel structure residential construction water only one item can save billions of tons of water a year. The fourth is beneficial to environmental protection. At present, the multi-storey residential structure system is mainly for the masonry structure and concrete frame structure, the use of Portland cement material, after the break-up of the building, it will become difficult to recycle waste, cause damage to the environment. At present, many developed countries are studying as much as possible reduce the dosage of cement products. Compared with light steel structure residential building system is very conducive to environmental protection.
To break through the bottleneck at present
Although multi-storey light steel structure residence is a new type of energy-saving and ground-saving residential system. But the popularizing this new type of housing system in our country, in addition to the lack of specific code of steel structure housing, policy support, two key problems to be solved, there are few practical talents, the steel structure housing costs are higher. Some construction standards remains to be perfect too.
Concerned expert thinks, multi-storey light steel structure housing development in China, problems are not exist in both raw materials and technology, development of multi-storey light steel structure housing the biggest obstacles and bottlenecks, is at present our country is much higher than other developed countries of the code for fire protection requirements. In America, for example, the United States regulations multi-storey light steel structure residential fire resistance as load bearing wall l h, and the provisions of the code for fire protection for at least 2.5 hours. The specifications after considering only the fire safety evacuation time, and in addition to considering the evacuation of the code for fire protection in our country, also considered salvage building and as much as possible. Thus, multi-storey light steel structure housing to meet the requirements of the code for fire protection, it must be taken out of the abroad is much more complicated technical measures, such as increase the layer number and thickness of fire prevention plasterboard, increase the automatic sprinkler system, etc. These will undoubtedly increase the multi-storey light steel structure residential construction costs, influences its popularization. At the same time, the light steel structure housing because it has excellent performance, and low maintenance cost, some developed countries adopted a positive policy support on it. In the United States, consumers to buy light steel structure housing insurance premium as long as 60% of timberwork residence. In Japan, many financial institutions to buy light steel structure residential consumers can increase the line, at the same time is also given to extend repayment period. Large population in our country, the shortage of land resources, the introduction and promotion of multi-storey light steel structure residence has more important strategic significance, should from the loan, taxes, insurance of the housing system to support.
Steel structure construction related standards remains to be perfect.Steel structure production, installation is a systemic industry, need to welding skilled operators. A specificationSteel structure enterpriseNo more than 10 years of experience accumulation, no big project construction performance, it is difficult to ensuresteel structure engineeringroduction and installation quality. Xi 'an construction engineering safety quality supervisory center in the city's eight areas of 17 steel structure building engineering quality for special inspection, found that thesteel structure engineeringConstruction quality is not optimistic, not only the common quality problems, and manysteel structure engineeringIn violation of mandatory provisions of the state, some engineering operation welder unlicensed mount guard.
According to introducing, our country is rightsteel structure engineeringSingle-row checks because, unlike a normal reinforced concrete than ten engineering, steel proportion in the whole building is much higher. Therefore, to ensure thatsteel structure engineeringConstruction quality, must first guarantee the steel used in accordance with national standards. Inspectors found that most of the construction unit to use steel, welding materials, high strength bolt and common bolt material, no corresponding varieties, specifications, performance and other test records, also lack of security based on the engineering use. At the same time, some small and medium-sized enterprises for welder certificate is whether or not a don't seriously, in the 17 units inspected, most of the construction personnel no HanGongZheng. somesteel structure engineeringNot yet the completion acceptance and filing, has been put into use, and the engineering supervision unit to cooperated-builing there was no.
Assembly at the scene of the steel structure housing, not only rarely seen common mud ground conditions, construction site and less noise, dust and construction waste, construction basic is not affected by the weather and season, greatly shorten the production cycle and capital takes up time. Is also for this reason, the steel structure housing is also called & other; Come off from the line of the residential & throughout; . Steel structure housing will bring China & other; QinZhuanHanWa & throughout; Type of traditional building model with great changes, so is known as & other Throughout the fourth revolution of residential &; . Huge business opportunities to attract the attention of many enterprises at home and abroad, iron and steel enterprises should actively plan for and present some demonstration projects, take concrete actions to meet the arrival of the Warehouse Building residential building boom.

Steel structure: super-tall large-span special modelling into the development direction
Steel structure: super-tall large-span special modelling into the development direction
When it comes to architectural form, especially in steel structure, for work, one might think of the "bird's nest", CCTV new site, the intime center... Throughout the urban construction, any large, the buildings in the form of invariably choose the steel structure, is the modern designer have a preference to its, builder is passionate about it? The author has come to CCTV new site project, and build three inningsSteel structure specialistOuYangChao spoke.
China Steel Structure Building http://www.jingtabuilding.com/steel-structure-building.html building late high starting point
Before no formal conversation OuYangChao introduces to the reporter a story first. A century ago, a lasted for three days and three nights of fire almost the entire Chicago reduced to ashes. Americans, however, take this opportunity to new torch lit the architectural art. With glass and steel as the material of each big buildings from all over the United States, even became a general chain steel structure...
It is reported, until the mid - 1980 - s, China steel structure building is still "zero". At this time, also, the late decades of western ChinaSteel structure construction, but on a high starting point, according to high standards and strict requirements, difficult start, develop rapidly. ChinaSteel structure constructionStarting point can be traced back to 1984, when the three zhongjian bureau winning China's first steel structure building, shenzhen development centre. At the time, the domestic construction of the main battlefield of concrete structure, steel structure construction is the virgin land. Quickly master the world advanced carbon dioxide gas shielded welding technology became the builder to complete the project in the hands of "an". So the agency 10 top welders dongdu fuso. Abnormal iron sichuan training center of Japan, experts in learned that most of them only junior high school culture, and asserts that "cultural foundation also have to learn 3 to 6 months, your learning contract period is only a month, when the time comes to have a third qualification is pretty good!" Face humiliation, 10 Chinese welders concentrated study seven hours a day, after school to discuss after the meal, and play. After 30 days, the 10 Chinese guy well completion. Later in shenzhen development center of construction engineering, they have played an important role, from welding refresh record was 110 mm 130 mm thickness, to 350000 linear meter by the ultrasound scanning zi powder flaw detection inspection qualified, again to 98% of the welding to the United States the highest standard of (D)... China's steel structure construction from now on will open the floodgates!
Large public Steel Sheds each has its own characteristics
OuYangChao said: "the steel structure is more popular now, and its modelling and construction difficulty is becoming more and more high, for example, now domestic representative public building of CCTV new site project, Shanghai international trade center, guangzhou TV tower as well as the national stadium project." CCTV's "new project both the height and the difficulty, is a challenge of irregular building structure construction, Shanghai international trade center is a tall building, guangzhou TV tower the tower structure itself has been very complicated, construction steel structure is more complex, the national stadium is called is the representative work of modelling." "CCTV", for example, its tilt overall two-way tilt (6 degrees) and double (70 m and 60 m respectively) structure, and in the diagonal direction of double pick structure under the action of gravity, there would be some sag; The steel used in the engineering level is higher, on averagesteel structure engineeringMostly used in Q345D or Q390D, while in "CCTV" project by Q420D and Q460D, this is rare in the general public, this is for steel fabrication and welding has led to a lot of technical difficulties and requirements; CCTV, the main consists of two towers, and are connected by a 14 layer of large cantilever structure, forming a huge "door" glyph. The model of traditional construction technology of daunting challenges. Cantilever under the action of gravity, sagging, requires reverse deformation in construction process, requirement in steel structure welding process still need to calculate the preset value, the value in the past almost can't use in the public; In addition, engineering measurement is also a problem, due to the structure and its each post should be high in the sky, if coupled with preset value, the difficulty of its installation will be bigger; As the steel level increase, its thickness is increased to 135 mm, long super thick steel structure welding up to 11 in the CCTV project, has now completed seven.
OuYangChao also told me that, like the "bird's nest" project of the steel structure is characterized by space curve structure, this creates higher demand for steel structure manufacture, because once appear error, are difficult to butt welding between steel structure, its welding process is also relatively more strict; The intime center project is regular, not very complicated, its construction is the biggest difficulty in 39 meters long truss assemble two root on the ground, and then use tower crane hoisting. The engineering part, shell back glyph forms the framework of on the whole, inner barrel is composed of 35 post, mainly for the high-speed elevator installation, requires the installation of the pillars in the construction of very precise and vertical degree, or in the elevator installation will be affected. Itc three period, the intime, he says, and all three are of super-tall nortel center project, and adopts the construction technology such as large span, long welding. Large public construction steel structure, so to speak, Beijing have difficulty and distinctive.
Super-tall large-span special modelling is the development direction
OuYangChao pointed out that the development direction of steel structure building is tall, big span, and special model from three aspects. Special modelling to guangzhou television tower and "CCTV", "bird's nest", these buildings have in common is not possible to use concrete construction. And at present such as capital, wuhan, baiyun airport and some of the modern railway station architectural form are connected to the space curve, the direction of large span, this structure can only be performed by steel structure in the form of a. In addition, the steel grade is higher and higher, steel structure building with steel quantity is becoming more and more big. Nortel center about 40000 tons, itc three periods of about 60000 tons, "CCTV" about 120000 tons.

When it comes to architectural form, especially in steel structure, for work, one might think of the "bird's nest", CCTV new site, the intime center... Throughout the urban construction, any large, the buildings in the form of invariably choose the steel structure, is the modern designer have a preference to its, builder is passionate about it? The author has come to CCTV new site project, and build three inningsSteel structure specialistOuYangChao spoke.
China Steel Structure Building http://www.jingtabuilding.com/steel-structure-building.html building late high starting point
Before no formal conversation OuYangChao introduces to the reporter a story first. A century ago, a lasted for three days and three nights of fire almost the entire Chicago reduced to ashes. Americans, however, take this opportunity to new torch lit the architectural art. With glass and steel as the material of each big buildings from all over the United States, even became a general chain steel structure...
It is reported, until the mid - 1980 - s, China steel structure building is still "zero". At this time, also, the late decades of western ChinaSteel structure construction, but on a high starting point, according to high standards and strict requirements, difficult start, develop rapidly. ChinaSteel structure constructionStarting point can be traced back to 1984, when the three zhongjian bureau winning China's first steel structure building, shenzhen development centre. At the time, the domestic construction of the main battlefield of concrete structure, steel structure construction is the virgin land. Quickly master the world advanced carbon dioxide gas shielded welding technology became the builder to complete the project in the hands of "an". So the agency 10 top welders dongdu fuso. Abnormal iron sichuan training center of Japan, experts in learned that most of them only junior high school culture, and asserts that "cultural foundation also have to learn 3 to 6 months, your learning contract period is only a month, when the time comes to have a third qualification is pretty good!" Face humiliation, 10 Chinese welders concentrated study seven hours a day, after school to discuss after the meal, and play. After 30 days, the 10 Chinese guy well completion. Later in shenzhen development center of construction engineering, they have played an important role, from welding refresh record was 110 mm 130 mm thickness, to 350000 linear meter by the ultrasound scanning zi powder flaw detection inspection qualified, again to 98% of the welding to the United States the highest standard of (D)... China's steel structure construction from now on will open the floodgates!

Method for numerical control
Method for numerical control, benefit from the power grid construction of steel structureMachine tool industry to develop in the direction of high added value. In recent years, under the condition of the domestic economy continues to high-speed growth, China's machine tool industry is developing rapidly. In macroeconomic regulation and control in the first half of 2008, under the influence of metal-cutting machine tool industry in our country has new changes: production growth fell to 10%, while the gold (186,0.68, 0.37%, right) cutting machine tool sales revenue growth remained at about 30%, shows that average unit price rise significantly, machine tool development towards high value-added machine tool market.
Company's main business prospect is good. The company's main products include: iron tower light steel structure numerical control of complete sets of processing equipment; Construction steel structure numerical control of complete sets of processing equipment; Large sheet of complete sets of processing equipment. Tower steel structure is mainly used in electric power equipment, under the background of countries promote the building of power grid, the products face a broad market space. Large plate mainly by wind power to drive numerical control of complete sets of processing equipment, are in growth stage. With the expansion of the steel structure industry, the phasing out of the traditional mode of production, steel structure numerical control of complete sets of processing equipment market prospect is good.
Company a competitive advantage is obvious. Steel structure numerical control of complete sets of equipment manufacturing industry is its early. Company from 2004 to 2006, tower steel structure CNC numerical control of complete sets of processing equipment, building Warehouse Building http://www.jingtabuilding.com/steel-structure-warehouse.html of complete sets of processing equipment of the total sales of 366 million yuan, accounting for 62.14% of the total amount of the domestic market sales and market share ranks the first. Company has been developing rapidly in the field of large plate CNC complete sets of processing equipment, the order 6 fold increase in the amount of 3 years.
Raising investment projects will greatly ease the capacity bottlenecks, reduce reliance on outsourcing company. This to raise money to spend, the numerical control processing equipment production project of steel structure is expected to reaches producing in 2012, after the project put into production will aggregate the new price of all kinds of complete sets of numerical control equipment 803 units/year, the existing production capacity increased by 1.88 times.
