Advantages of Steel Structures
-
Large-Span Flexibility: Suitable for single or multiple spans, ideal for large industrial plants, warehouses, and commercial buildings.
-
Cost-Effectiveness: Competitive pricing (approximately USD 50–80/m²), low maintenance costs, and a lifespan of 20–50 years.
-
Fast Construction: Prefabricated components enable efficient on-site assembly, significantly reducing project timelines.
-
Durability & Safety: Excellent resistance to earthquakes, wind, and snow loads; corrosion, insect, and mold proof.
-
Eco-Friendly: Compatible with insulation panels, skylights, and ventilators to maximize natural lighting and energy efficiency.
Technical System & Components
-
Primary Frame: Steel columns, roof beams/trusses (portal frame), crane beams (optional).
-
Stability System: Roof bracing, vertical bracing, tie rods.
-
Secondary System: Roof purlins, wall girts (with bridging).
-
Critical Connections: Gusset plates, HSFG bolts, welds, anchor rods.
-
Special Components: Wind columns, knee braces, crane runway bracing.
All structures are designed in compliance with international standards (AISC, Eurocode, GB, etc.) and include anti-corrosion (galvanizing/painting) and fire protection (intumescent coatings/boards) for safety and compliance.
