Prefabricated Portal Steel Structure Building Large Span Factory Warehouse Construction
Our prefabricated steel frame building adopts stable portal rigid frame structure with high-strength steel as main material. It features excellent wind resistance, seismic performance and anti-rust property. All components are pre-fabricated in our factory and connected by high-strength bolts on site, which greatly shortens construction period. Flexible layout design, recyclable materials and low later maintenance cost make it an ideal choice for industrial, storage and commercial construction projects.
Structural System: Adopt pre-engineered portal rigid steel frame bearing system, available in single-span, double-span and multi-span structural forms. The overall structural design strictly complies with international load standards, with targeted calculation for wind load, snow load, live load and dead load according to local meteorological and geological conditions of the project location, ensuring overall structural stability and long-term safety under complex natural environments.

- Excellent seismic and wind resistance performance: This steel structure system features reasonable force transmission and high overall structural rigidity. Through professional calculation of local wind load, snow load and seismic intensity, the building can resist severe weather and geological impacts effectively, with higher safety stability than traditional concrete buildings.
- Fast construction speed and short project cycle: All main steel components are precisely prefabricated and processed in our factory. Only high-strength bolt assembly is required on site without a large amount of field welding work, greatly shortening construction time and enabling customers to put the building into use much earlier to create economic benefits.
- Light self-weight and cost-saving foundation investment: Steel frame is lighter than reinforced concrete structure under the same load-bearing requirement, which reduces pressure on the foundation. It can adapt to various complex geological conditions and significantly cut foundation engineering cost and overall project budget.
- Components are palletized with clear marking, and fully inspected throughout production to ensure qualified shipment.
- Strict incoming material inspection plus in-process checking guarantee stable steel structure quality.
- Reasonable packaging prevents transport damage, while multi-step QC controls product precision strictly.
- Every batch undergoes finished product inspection before packing to avoid missing or defective parts.
- Small accessories are individually packed, and main steel members are secured against deformation at sea.
- Complete inspection records are reserved, supporting full traceability of all structural components.
