The so-called “light steel villa” is mainly made of light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology. After precise calculation and the support and combination of auxiliary components, it plays a reasonable bearing capacity to replace traditional houses. The weight of the floor structure system of the light steel villa is only one fourth to one sixth of that of the traditional concrete floor system in China, but the height of its floor structure will be 100-120 millimeters higher than that of ordinary concrete slabs.
