Metal Buildings Specification

The metal buildings uses steel to form a load-bearing structure. Generally, beams, columns, trusses, and other components made of section steel and steel plates constitute a load-bearing structure, which together with roof, wall, and floor, form a building.

Compared with traditional concrete buildings, metal structure buildings use steel plates or section steel instead of reinforced concrete, higher strength, and better seismic resistance. And because the components can be manufactured in factories and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and become more environmentally friendly. Therefore, it is widely used in industrial buildings and civil buildings all over the world.

1. Greatly save construction time. Construction is not affected by the season
2. Increase the use area of buildings, reduce construction waste and environmental pollution
3. Building materials can be reused, stimulating the development of other new building materials industries
4. Good seismic performance, easy to transform, flexible and convenient in use, bringing comfort and so on
5. High strength, lightweight, high safety and wealth of components, and lower building cost

1. Heat-resistant and non-fire-resistant, fire-resistant coatings are required
2. It is susceptible to corrosion, and the surface needs to be coated with anti-corrosion coatings to reduce or avoid corrosion and increase durability
