Light steel structure usually refers to the structure composed of the following steels: cold-formed thin-wall steel structure; Hot rolled light steel structure; Welded or high-frequency welded light steel structure; Light steel pipe structure; A structure composed of welded composite beams and welded composite columns with thin plate walls.
For single-storey industrial plants, usually H-shaped steel, the use of welded connections as beams and columns, C-shaped or Z-shaped light steel purlins, roof systems or floor systems with pressed colored steel plates for the surface layer, the above can be poured concrete, pressed steel can be used as rebar, if necessary, can also be rereinforced. The wall enclosure can also be single-layer or sandwich molded steel plate, and various insulation layers can be filled inside the sandwich plate.
Advantage
1.Short cycle
The biggest advantage of light steel structure is that all components can be made by the factory and installed on site, which only takes 45 days to 2 months for generally small industrial plants, while the use of reinforced concrete buildings takes about 8 to 12 months.
2.Good comprehensive economic benefits
The construction period of light steel structure is short, and it can be used in advance to obtain investment benefits in advance. In addition, due to the use of colorful molded steel plates, beautiful and gorgeous, improve the dynamic sense of the surrounding environment. Because of the light weight of the building itself, it is generally not necessary to do pile foundation, which can save investment. The effect of heat preservation, heat insulation and seal separation is better when the polystyrene styrene foam sandwich board or single board is added with thermal insulation cotton. The color steel plate is galvanized as the substrate and silicone as the surface, after two division and two drying processing, durability is also good.
3.Material toughness
Because the steel structure is a flexible structure with light weight, it can effectively reduce the degree of earthquake response and disaster impact, and is very conducive to earthquake resistance.
4.Suitable for disassembly and relocation
When the site is not satisfied or unexpected changes in the external environment, the entire building can be demolished in a very short time, with minimal loss, which is conducive to protecting the environment and saving resources, which are not available in reinforced concrete buildings.
