Heavy-Duty S350 4mm Hot Galvanized Steel Bridge Decking: High-strength S350 structural steel decking with 4mm thickness and hot-dip galvanized finish. Specially engineered for box arch bridges, delivering outstanding rigidity, corrosion resistance and heavy load bearing capacity.

• Product Positioning – Robust composite steel decking fabricated from S350 high-strength steel at 4mm thickness, engineered to satisfy rigorous bridge and infrastructure construction demands.
• Core Strengths – Features 350 MPa minimum yield strength together with hot-dip galvanized anti-corrosion treatment, delivering excellent load-bearing capacity, outstanding fatigue resistance and extended service life under harsh operating conditions.
• Decking Application – Functions as permanent formwork and structural composite layer for concrete bridge slabs; also suitable as independent steel deck for pedestrian and light-traffic bridges.
• Quality Assurance – Produced in ISO 9001 & EN 1090 certified workshops. Complete traceable mill certificates and galvanizing inspection reports are supplied to meet global project standards.

• Product Positioning – A complete, custom‑engineered steel arch bridge solution, covering primary structural members, secondary framing, and durable decking systems for highway, railway, and pedestrian applications.

• Core Strengths – Total customisation from design to delivery – every component is fabricated to project‑specific radii, spans, and load classes, with integrated corrosion protection through hot‑dip galvanizing or advanced coating systems.

• Typical Applications – Ideal for highway overpasses, railway arches, landscape pedestrian bridges, and industrial access structures requiring both aesthetic appeal and heavy‑load capacity.

• Quality Backing – Manufactured under strict compliance with AASHTO, AWS, and AISC standards, ensuring structural reliability, safety, and long‑term performance in all climatic conditions.
