Meanwhile, the steel has good elastic, plastic and impact resistance, in general, the steel’s ability to adapt to the dynamic load compared strong, its modern steel frame homes good ductility and energy dissipation capacity can ensure that it does not because of changes in the external load suddenly rupture, light steel structure seismic steel which is very favorable. European construction steel requirements yield ratio is less than 0.91, while Japan requires construction steel yield agricultural equipment repository ratio of less than 0.80. Structure section and thinning wall body reduction and to improve the effective usage of area of the building by 5% ~10%. The most important thing is to choose a regular steel structure manufacturer. The lower the yield ratio, the ability of steel to resist strong earthquakes stronger, Indoor plumbing is completely hidden electrical lines between the wall and the floor, flexible layout, easy to modify. Among them, the yield ratio is an important parameter to measure the ability of steel hardening, It prefab steel building reduces two big conflicts of materials transportation and materials needs, if it is 20% reduction in traditional buildings prefabricated workshop supplier materials. Metal protective layer (surface alloying zinc, aluminum steel structure platform plating, etc.). Because of homogeneity and toughness of steel materials, may have large deformation, can well withstand dynamic loads, with good seismic capacity.
