Steel Structure Highway Bridge

✅ Short Construction Period Main steel girders and components are fully prefabricated in factory. Only assembly and bolt connection are required on site. Greatly reduce on-site wet construction and shorten the whole project schedule.

✅ Excellent Structural Performance High strength-to-weight ratio of steel materials. The structure features strong bearing capacity, good toughness, outstanding anti-seismic and anti-fatigue performance, adapting to long-term repeated vehicle load of highway traffic.

✅ Light Self-weight, Lower Foundation Cost Lighter dead load compared with concrete bridges. It effectively reduces foundation engineering workload and saves investment, especially suitable for complex terrain such as mountainous areas, rivers and soft ground.

✅ High Durability & Controllable Anti-corrosion System We support complete anti-corrosion coating schemes: shot blasting treatment, epoxy primer, intermediate paint and topcoat. Optional fire protection coating can meet local specification requirements, extending service life of steel members.

✅ Convenient Maintenance & Easy Inspection Open steel girder structure facilitates daily inspection, anti-rust maintenance and later reinforcement work. Damaged components can be replaced separately without large-scale traffic interruption.

✅ Flexible Customization & Wide Adaptability Available for steel I-girder, box girder, truss girder solutions. Applicable for urban viaducts, river-crossing highway bridges, overpasses and temporary highway passage bridges.

✅ Environmentally Friendly & Recyclable Steel materials can be 100% recycled after service life. Less construction waste is generated during fabrication and installation, complying with low-carbon infrastructure standards.

Product Details

Steel Structure Highway Bridge mainly adopts hot-rolled H-beams, I-beams, steel box girders, steel trusses and steel plates as primary load-bearing members. All steel components undergo precise factory processing including CNC cutting, automatic welding, drilling, shot blasting and anti-corrosion coating before delivery. Components are transported to the construction site and assembled by high-strength bolts, minimizing cast-in-place concrete operations.

We can supply single-box / multi-box steel box girder bridges, plate girder bridges and steel truss bridges to match different span requirements for highway projects. The design strictly follows international bridge design standards. Combined with bridge deck slab, expansion joints, bearing supports, guardrail and drainage system, we provide a complete set of highway bridge steel superstructure solutions.

For anti-corrosion protection, multiple coating systems are optional according to local climate: inland atmospheric environment, coastal high humidity and salt fog environment. When required, intumescent fire retardant coating can be applied to achieve specified fire resistance grade.

Different from traditional concrete bridges, steel highway bridges possess remarkable advantages in spanning capability and construction speed. They are widely used in provincial highways, urban viaducts, grade-separated interchanges, river-crossing traffic passages and emergency temporary bridges.

Our team provides integrated services including structural calculation, construction drawing optimization, component fabrication, export packaging, loading arrangement and on-site technical guidance. We have abundant experience for overseas infrastructure projects and can customize steel bridge components to satisfy regional engineering codes in South America, Oceania and other markets.
