structural steel fabrication engineeringTo the demand of production of steelNow in many buildings of the use of steel structure building in our country, many of the buildings have seen a lot of. But assteel structure engineeringUsed in steel material, a lot of building and puts forward a lot of requirements.
Steel structure building is a new type of energy conservation and environmental protection building system, known as the 21st century and who Green building and throughout . Because of light weight, high strength, good seismic performance, and has advantages of comprehensive use cycle, accord with the national economy sustainable development requirements, so has great development space. In recent years, due to the government to strengthen the policy guidance, make steel structure development present application fields expand, dosage of the surge in good situation. At the same time, by baosteel as a representative of the domestic various steel after long-term unremitting efforts, developed a batch of cost-effective structure steel, for a large number of outstanding domestic steel structure building was provides favorable conditions. At present, more and more high-rise buildings, large factories, big span space structure, the transport of energy engineering and residential building, steel structure as building support a preferred material, widely and the use of. The domestic steel structure production by 2002 tons soared to 26 million tons last year.
At present, the steel structure products are mainly divided into heavy, large component and light steel, rack, color plate. Steel structure products used steel varieties of proportion is, medium thickness plate about 60% above, hot rolled H section steel pipes is about 15%, 9%, other caitu and cold bend section is about 10%. Use steel structure material field, building 35%, public buildings and Bridges were 10%, 25%, high-rise residential building tower mast is occupied 6%, non-standard and other up and down around 15%.
Steel production enterprises should seize the country's recent development hotspot and focus, the production of market need and applicable steel structure material. At present domestic energy construction to speed up infrastructure, including nuclear power plant building steel, wind power generation steel, boilersteel frameSteel etc, present long-term and heavy demand state; Traffic engineering of bridge steel proportion increased, railway, highway bridge using steel structure has become a development trend; The subway, light rail, city overpass and elevated and municipal construction steel quantity, also will continue to increase; In the state advocates energy saving, material recycling big background,Steel structure housingBuilding will present the trend of the development of the geometric level. Among them, the steel plate, hot rolled H section steel, steel tube, cold bend section steel is the main products, steel strength for Q345, Q235 brand of product, is the first choice of downstream users.
