Need a durable, traffic-friendly bridge for cars, trucks, and buses? Our steel structure highway bridge fits the bill. Perfect for highway expansions, urban ring roads, and rural connections, it pairs tough steel frames with road-focused design-offering stable lanes, heavy-truck capacity, and quick modular builds that keep traffic moving. Ideal for projects where vehicle safety, smooth flow, and low construction disruption matter most.
Key Features & Material:
Made of Q355NH weathering steel + Q550 high-strength steel, it uses 88% prefab bolted modules (cuts road closure time). Surfaces get anti-skid coating + 2h fireproof finish + anti-rust treatment. BIM design includes lane marking reserves, emergency phone ports, and drainage systems-fits sedans, freight trucks, and public buses.

Advantages:
Weathering steel resists road salt and rain for 80+ years, low maintenance. Anti-skid surface prevents car skids in bad weather. Prefab modules let us build at night, no daytime traffic jams. Flexible steel handles heavy truck vibrations without cracking. Built-in drainage stops water pooling, extending bridge life.
Services:
We offer traffic diversion plans, road marking construction, and load testing for freight routes. Our team provides on-site assembly supervision and quotes within 6 hours. After-sales includes 30-year structural warranty and annual anti-skid + drainage checks.
