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.

• Space efficiency: Steel structure residences can better meet the requirements of flexible partitioning of large bays in buildings than traditional buildings. By reducing the cross-sectional area of columns and using lightweight wall panels, the area utilization rate can be increased, and the effective indoor area can be increased by about 6%.
• Energy efficiency: Good energy-saving effect. The wall adopts light-weight energy-saving standardized C-shaped steel, square steel, and sandwich panel, which has good thermal insulation performance and good earthquake resistance. Energy saving by 50%.
• Safety: The use of steel structure system in residential buildings can give full play to the good ductility of steel structure, strong plastic deformation ability, excellent seismic and wind resistance, and greatly improve the safety and reliability of residences.
• Lightweight construction: The total weight of the building is light, and the weight of the steel structure residential system is light, about half of that of the concrete structure, which can greatly reduce the basic cost.
• Fast construction: The construction speed is fast, and the construction period is at least one-third shorter than the traditional housing system. A 1,000 square meter building only needs 20 days and five workers can complete the construction.
• Eco-friendly: Good environmental protection effect. The steel structure house construction greatly reduces the amount of sand, stone, and ash. The materials used are mainly green, 100% recycled or degraded materials.
