Carbon structural steel (q195.q215.q235.q255.q275, etc.) is used for steel structure Low alloy high strength structural steel High quality carbon structural steel, alloy structural steel and special steel.

The steel structure will be affected by various forms during use (load, uneven foundation settlement, temperature, etc.), Therefore, the steel is required to have excellent mechanical properties (strength, plasticity, resistance) and processing properties (cold and hot processing and welding properties) to ensure the safety and reliability of the structure.

The steel structure system used in residential buildings can give full play to the outstanding ductility of steel structures. It has strong plastic deformation ability and excellent seismic and wind resistance performance, which greatly improves the safety and reliability of housing. Especially in the case of earthquake and typhoon disasters, steel structures can avoid the collapse of buildings and road damage.
