Prefabricated Steel Structure Building Overview
Prefabricated steel structure buildings are engineered around core principles of high-efficiency assembly, time-saving construction, and worry-free operation. All main steel frames (H-shaped steel columns, steel beams) and secondary frames (purlins, tie rods) are manufactured using standardized prefabrication in our factory.
Material Specifications & Quality Standards
Primary materials include Q355B (equivalent to S355JR, ASTM A572 Gr.50) and Q235B (equivalent to S235JR, ASTM A36), strictly adhering to ISO quality systems. Through automated cutting, precise welding, and standardized anti-corrosion treatment (sandblasting + double-layer primer + topcoat/hot-dip galvanizing), component accuracy is controlled within ±2mm, eliminating the need for on-site secondary processing.
Construction Advantages
On-site construction requires only rapid splicing with high-strength bolts, eliminating extensive welding and wet work. This enables simultaneous progress of factory production and on-site foundation work, significantly reducing labor input and on-site management costs.

Core Structural Classification
- Portal Frame: Factory-prefabricated H-beam structure, bolt-connected. Cost-effective for small factories and temporary buildings.
- Large-Span Truss/Grid: High-strength steel with 30–100m column-free spans. Ideal for heavy-duty factories, stadiums, and exhibition centers.
- Modular Integrated: Fully finished room modules, bolt-assembled on-site. Fast for apartments, hotels, and resettlement housing.
- Steel Frame-Braced: Prefab columns/beams with lateral bracing. Superior seismic/wind resistance for mid-rise offices and residences.
- Custom Special-Shaped: Tailor-made irregular steel components. Creates unique curved/zigzag designs for high-end commercial projects.
