How to make the roof of light steel villa?
1. The roof structure frame is made of light steel materials, which is generally a large pitched roof or herringbone roof, and then covered with multilayer plywood or chipboard.
2. Then lay asphalt felt, hang tile strips and mount tiles, or directly use sand asphalt shingles on the asphalt felt.
3. For beams and structural columns with concentrated load, light steel materials are also used to connect them into load-bearing beams and columns through appropriate combination.
4. The wall and floor are hollow floors, and there are reserved holes on the keel, so all pipelines can easily pass through the wall and floor.
5. The roof appearance of light steel structure can have multiple combinations and materials. On the premise of ensuring waterproof technology, there are many options for appearance.
The cost of light steel villa roof
The cost of the roof has a lot to do with the materials. The construction cost of light steel structure villa roof and material belt is $210 – $320 per square meter. The light steel keels used include ceiling keels and partition keels according to their purposes, and V-shaped, C-shaped, T-shaped, L-shaped and U-shaped keels according to the section form.

Most of the roofs of power houses are 15 °, and the maximum slope can reach 75 °.
Advantages of light steel villa roof structure
