Wiskind steel building in the United States is very durable. It is strong enough to withstand heavy snowfall, high winds, and strong earthquakes, wall and roof used aluminum-zinc metal sheet to prevent rusting and increase the life, all the Steel Structure can fabricate in factory and installation on site without secondary welding just connected the bolt, easily and fast construction, save man power. Steel Shed Building has a good seismic performance, light steel structure belongs to the flexible structure, which can effectively reduce the seismic response and disaster impact, highly conducive to the earthquake.
