The core material of light steel villa houses is the light steel main keel generated by hot-dip galvanized steel plate through cold tying technology. Through precise calculation and the support and fusion of auxiliary components, it has a scientifically reasonable bearing capacity to replace traditional houses. Compared with concrete structure housing, the construction steel of light steel villas can be reused, while the concrete cannot be reused; Concrete causes environmental effects and is not beneficial to health, but light steel construction does not require concrete at all, so there is no such situation.
