Product Description

Our ASTM-Engineered Hot-Dip Galvanized Steel Arch Bridge is a high-standard prefabricated heavy-duty structural solution for modern municipal, highway and railway infrastructure. Fully designed and fabricated per ASTM international specifications, this steel arch bridge features excellent structural rigidity, heavy load-bearing capacity and superior corrosion resistance.

Adopting full factory prefabrication, it minimizes on-site construction work, shortens project cycle and reduces labor costs. It is an ideal durable and cost-effective crossing solution for river spans, urban overpasses and scenic landmark projects.

ASTM-Compliant Structural & Material Quality
All main arch ribs, deck systems and bracing components adopt ASTM A572 Gr.50 / A709 Gr.50W high-strength steel. With stable yield strength and excellent low-temperature toughness, the material resists heavy dynamic loads, seismic impact and extreme weather conditions.

All welding procedures follow AWS & ASTM standards, with finite element structural analysis applied for every stress node. It ensures overall structural balance, uniform load transfer and long-term structural stability.

Premium Hot-Dip Galvanized Anti-Corrosion Performance
All steel components are processed with standard ASTM A123 hot-dip galvanizing. The integrated zinc coating effectively isolates steel from oxidation, UV radiation, rainwater and salt corrosion.

Standard galvanized coating meets daily industrial environment demands, while upgraded Z600 thickened galvanization is available for coastal and heavily corrosive areas. The advanced surface treatment guarantees decades of stable appearance and structural performance with low maintenance.
