Key features

Heavy Load & Long Span Design: Engineered to withstand high traffic volumes and extreme weather, supporting spans from 10m to over 100m with high-grade structural steel (Q345D/Q420)

Superior Weather & Corrosion Resistance: Utilizes weathering steel (Corten A/B) or advanced hot-dip galvanizing/painting systems (ISO 12944)

Factory prefabrication ensures high precision and quality. Bolted connection design allows for rapid on-site assembly, significantly reducing construction time and labor costs, ideal for remote areas.

From Free Body Diagram (FBD) and AutoCAD to TEKLA models, we provide full shop drawings. Customized span, width, and load capacity are available per project requirements.

Product Q&A

Q:Do you provide design and installation drawings?

Yes, we have an in-house engineering team. After you provide the required span, load capacity (truck load/uniform load), and width, we can provide detailed shop drawings and installation manuals for your review before mass production.

Q:What certifications do you hold for bridge manufacturing?

We strictly follow international standards. Our welding procedures are qualified under AWS or ISO 3834. We can also provide material mill certificates (EN 10204 3.1/3.2) upon request. Third-party inspections (SGS, BV) are always welcome.

Q:Can you send engineers to supervise the installation on site?

Yes, we can dispatch our technicians or engineers to your project site to guide the installation, or we can provide online video technical support to help solve any on-site issues.
