We supply prefabricated heavy steel structures for large-scale municipal infrastructure. Our fabrication facilities are equipped to handle large-span steel box girders, steel-concrete composite beams, and interchange ramp structures. We ensure strict dimensional tolerance and high welding quality to meet demanding transportation loads and environmental conditions.
This project involved the fabrication and assembly of the primary steel structures for a major municipal elevated highway. The design utilizes a steel-concrete composite structure to balance construction speed, span length, and dead load.
Based on typical engineering requirements for projects of this scale, below are the standard materials and specifications we supply for heavy bridge structures. We can adjust standards (GB, ASTM, EN) based on your local regulations.
| Structural Component | Material Standard (GB / International Equivalent) | Typical Specifications | Application |
|---|---|---|---|
| Main Girders | Q355qD / Q420qD (Bridge Steel) Equivalent to ASTM A709 Grade 50 |
Thickness: 16mm - 40mm | Steel box girders, I-beams, main load-bearing structures |
| Secondary Structures | Q355B / Q235B Equivalent to S355JR / S235JR |
Thickness: 8mm - 20mm | Stiffening ribs, cross frames, diaphragms |
| High-Strength Fasteners | Grade 10.9 (GB/T 1228) | M22 / M24 | Splicing joints for main girders and site assembly |
| Shear Connectors | ML15 (GB/T 10433) | M19 x 120mm / 150mm | Welded studs connecting the steel girder to the concrete deck |
| Welding Consumables | ER50-6 (Wire) / F5031 (Flux) | 1.2mm / 1.6mm | SAW (Submerged Arc Welding) and GMAW for main seams |
| Surface Treatment | Epoxy Zinc-Rich Primer + Polyurethane Topcoat | 200μm - 250μm (Total Dry Film) | Heavy-duty anti-corrosion for C3/C4 exterior environments |
