Construction Pre-Engineered/Prefab Customized Steel Structure Building Workshop

Steel Warehouse refers to the internationally common portal frame steel structure system that can bear and transfer loads by connecting steel plates and hot-rolled, cold-formed or welded profiles through connectors.

It is made of light H-shaped steel (welded or rolled; variable cross section or equal section) made of portal frame steel support, C-shaped, Z-shaped cold-formed thin-walled steel is used as purlins and wall beams, and profiled steel plates or lightweight sandwich plates are used as The roof and wall envelope structure is a door-type steel frame steel structure system assembled by using high-strength bolts, ordinary bolts and self-tapping screws and other connectors and sealing materials.
