Prefabricated steel bridge is a modular steel bridge solution used for industrial access, temporary traffic, construction sites, river crossings, plant areas, mining roads, and emergency projects. The bridge components are fabricated in the factory and transported to the site for assembly, reducing on-site welding and shortening the construction period. For customers who need a strong, practical, and transportable bridge structure, prefabricated steel bridge offers good flexibility in span, width, load level, deck type, and connection method.
Our factory produces prefabricated steel bridge with attention to both structural strength and installation convenience. A bridge is different from ordinary steel fabrication because it must handle repeated loads, outdoor weather, vehicle movement, and long-term safety requirements. We review details such as main girder structure, cross beam layout, deck plate, guardrail, anti-slip surface, corrosion protection, bolt connection, and shipping size. For overseas contractors and distributors, this helps reduce installation uncertainty and makes the bridge easier to deliver as a complete project package.

Application Areas
Industrial Plant Access
Used inside factories, power plants, shipyards, and equipment yards for vehicle or pedestrian access.
Construction and Temporary Roads
Suitable for temporary traffic routes, construction crossings, and site access bridges.
Mining and Heavy Equipment Areas
Can be customized for heavy-duty access where strength and quick installation are required.
Overseas Engineering Projects
The prefabricated design allows bridge parts to be packed and shipped more easily for international project use.
Factory Strength
We have strong fabrication capability for steel structures and customized metal equipment. Our production equipment includes cutting machines, bending machines, drilling machines, welding machines, rolling machines, shot blasting equipment, painting equipment, and lifting equipment. These facilities allow us to process large bridge components and control key fabrication steps.
Our factory has accumulated experience in steel structure design and construction projects. This experience is useful for prefabricated steel bridge production because bridge components must be accurate, strong, and easy to assemble after shipment.
Customization Capability
We support customized bridge fabrication based on customer drawings or project requirements. Customers can provide span, width, load requirement, usage type, installation environment, deck type, railing requirement, and surface treatment standard. Our team will communicate before production and provide a production schedule after confirming the drawing.
For custom-made bridge projects, we can share photos and videos during fabrication. This helps overseas buyers check progress, confirm details, and coordinate the local installation plan in advance.
Quality Control, Delivery and Payment
We inspect bridge components before packing, including dimensions, welds, bolt holes, surface coating, component numbers, and accessory completeness. Third-party inspection is accepted. For standard products, the production cycle can be around 25 days, while customized bridge projects depend on drawing complexity and project scale.
We support EXW, FOB, and DDP terms. Standard payment terms are usually 30% advance payment and 70% balance before shipment. For customized products, advance payment is generally 50%–60%, with the balance paid before delivery. Large-volume orders can be discussed according to project quantity.
