Prefab Steel Industrial Building / Steel Frame Industrial Buildings Construction
Prefab Steel Industrial Building / Steel Frame Industrial Buildings Construction. This is a heavy industrial steel workshop for rail traffic equipment product. We design the proposal and drawing, fabrication for the steel structure components, installation for the steel structure, overhead crane, roof and wall insulation panel for this project.
Because of the height of this steel workshop building and heavy capacity of overhead crane, we design the steel column to be latticed steel column, it could bear large load from the crane and wind load and also save steel quantity.
Steel frame structure bulidings has lots advantages compared with concrete building such as high strength, large span, simple construction, short construction period: all components are prefabricated in the factory, the site is simply assembled, thus greatly shortening the construction period, a 6000 square meters of buildings, only 40 days to complete the basic installation.Beautiful and practical: the steel structure building line is simple and smooth, has the modern feeling.Color wall panels are available in a variety of colors, and other materials can be used for the wall, so it is more flexible.Reasonable cost: the steel structure building is light in weight, which reduces the basic cost, and the construction speed is fast, which can be completed and put into production as soon as possible. The comprehensive economic benefit is much better than the concrete structure building.
