Our steel structure systems are engineered for durability and performance across various industrial applications. The portal frame design provides optimal strength-to-weight ratio while allowing for flexible space utilization.

The main structural components utilize high-strength Q355B steel (GB/T 1591 compliant) with secondary elements in Q235B. Standard sections include hot-rolled or welded H-beams with web heights from 200-1200mm and flange widths of 200-600mm.

Our designs accommodate spans from 12-48 meters (extendable to 60m for special applications) with eave heights customizable between 6-30 meters. The roof slope is optimized between 5-10% for proper drainage and snow load distribution.
The structural system is designed to handle various loads including: dead loads (0.2-0.5 kN/m²), live loads (0.3-0.5 kN/m²), wind loads (0.45-0.8 kN/m² per GB 50009-2012), and crane loads (5-50 ton capacity).

Connection details feature high-strength grade 10.9 bolts combined with end-plate welding (GB 50017-2017 compliant). The bracing system utilizes cross-braced round steel ties (Φ20-Φ30) or angle steel for enhanced lateral stability.
Surface treatment includes shot blasting (Sa2.5 grade) followed by epoxy zinc-rich primer (80μm) and fluorocarbon topcoat (40μm), providing salt spray resistance exceeding 3000 hours. Optional intumescent coatings offer fire resistance from 0.5-2.5 hours per GB 14907-2018.
