Description
Heavy-Duty Steel Structures for Municipal Bridges & Elevated Highways
Heavy Steel Structures for Bridges & Elevated Highways

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.

Project Case: Fengtai New Area Elevated Road

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.

Total Length: 3,167.88 meters
Deck Width: 26 meters
Traffic Capacity: Two-way, 6-lane highway
Ramp System: 8 integrated on/off ramps
Project Investment: Approx. 640 Million RMB
Technical Specifications & Material Grades

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
Manufacturing Capabilities
  • Cutting & Plate Preparation: CNC flame and plasma cutting for thick steel plates.
  • Welding Process: Fully automated Submerged Arc Welding (SAW) for main girder seams, ensuring 100% UT/MT Non-Destructive Testing (NDT) pass rates.
  • Pre-assembly: Factory trial assembly prior to dispatch to guarantee smooth installation on the construction site.
