Fanglin Haotian's "light steel villa", whose main material is a light steel keel synthesized from hot-dip galvanized steel strip through cold rolling technology. After accurate calculation and support and combination of accessories, it plays a reasonable bearing capacity to replace Traditional houses.
     Special properties:
1. Compared with traditional residences, light steel villas have their outstanding advantages:
(1) The light steel structure parts manufacturing of light steel villas is highly industrialized and mechanized, and highly commercialized.
(2) The construction speed of the light steel villa is fast, and it will not affect the nearby residents, which is beneficial to civilized construction.
(3) The steel structure of the light steel villa is an environmentally sustainable product.
(4) Light steel villas have light weight and good seismic performance.
(5) The comprehensive economic index of light steel villas is not higher than that of reinforced concrete structures.
(6) Compared with brick-concrete houses, light steel villas can avoid the waste of resources caused by burning bricks with soil.
(7) Light-steel villas have a smaller wall thickness than light-steel structures, which can increase the effective use area than brick-concrete structures;
(8) Compared with steel-reinforced concrete houses, light-steel villas can be recycled in the future, but the concrete cannot be recycled. It must be construction waste in the future, causing environmental pressure and it will take 40 years for the concrete to dry Therefore, it is easy to cause indoor humidity and humidity, which is not good for human health. However, light steel structures do not use concrete at all, so this problem does not exist.
(9) Light steel villas have good seismic performance. As the earthquake activity is left and right and up and down, the light steel structure connected with screws constitutes a safe and stable box, and the wall will not collapse or the floor will be endangered by the earthquake.
(10) The construction of light steel villas adopts dry construction method, which will not cause waste of water data. And save money.
