Advantages of multi-storey steel plant

1. High strength, light weight. Steel has a higher strength and elastic modulus than other building materials such as concrete, masonry and wood. Therefore, the structure of light weight, small section, especially suitable for large span, large load of components and structures. Even with the use of less strong steel, the strength to density ratio is much greater than concrete and wood, so steel structures under the same stress conditions under the lighter weight.

2, the steel structure workshop component section is small, large effective space. Due to the high strength of steel, small section, small space. Taking simply supported beams under the same stress conditions as an example, the height of concrete beams is usually 1/10-1/8 of the span, while the height of steel beams is about 1/16-1/12. If the steel beam has enough lateral support, it can even reach 1/20, effectively increasing the net height between floors of the steel structure workshop. In beam height, under the same conditions, the steel structure bay is 50% larger than the concrete structure bay, which can better meet the requirements of large bay and flexible building division.

3, the material is uniform, plastic, good toughness, superior seismic performance. Because the steel structure is uniform and nearly isotropic, the actual performance of the steel structure conforms to the theoretical calculation model currently used, so the reliability is high.

Four is simple production, short construction period, multi-layer steel structure plant materials are simple, mostly finished or semi-finished materials, processing is relatively simple, can use mechanical operation, easy to shape and standardization, high degree of industrial production. Therefore, steel components are generally manufactured in specialized metal structure processing plants, with high precision, stable quality and low labor intensity.

5, steel structure workshop energy saving, environmental protection, compared with the traditional masonry structure and concrete structure, steel structure belongs to the green building structure system. The walls of steel structure factory houses are mostly made of new lightweight composite wall panels or lightweight blocks, such as high-performance NALC board, and the floors are mostly made of composite floor panels, such as molded steel plates, which meet the requirements of building energy conservation and environmental protection and can achieve the goal of saving energy by 50%, greatly saving energy.
