Heavy-Duty Galvanized Steel Bridge Deck | G500 Steel, Z275 Anti-Corrosion Coating

Structural Steel Bridge Deck | Ideal for Heavy-Duty Bridge Infrastructure

Our heavy-duty galvanized steel bridge deck is a high-performance structural flooring solution customized for bridge and infrastructure projects. Constructed from G500 high-strength steel with Z275 hot-dip galvanized coating, it features excellent load-bearing capacity, reliable corrosion resistance and outstanding outdoor durability. Designed with integrated stiffeners, the deep trapezoidal profile forms a tight composite structure with cast-in-place concrete slabs. Widely applicable to highway bridges, railway viaducts, pedestrian overpasses and heavy-load parking structures, it delivers long-span performance, fast installation and international standard certification, serving as a cost-effective and durable flooring option for global infrastructure construction.
 

Core Advantages

1. High-Strength Steel & Premium Anti-Corrosion Protection

Manufactured from G500 structural steel with a minimum yield strength of 500 N/mm², it boasts an optimal strength-to-weight ratio. The double-sided Z275 galvanized layer (total 275g/m²) effectively shields the steel from moisture, deicing salts and atmospheric corrosion. No extra on-site painting is required, cutting construction expenses and long-term maintenance costs greatly.

2. Optimized Profile for Excellent Structural Properties

The 210mm deep trapezoidal rib is fitted with longitudinal and transverse stiffeners, improving bending resistance and load distribution efficiency. Wider girder spacing can be adopted to lower steel consumption without compromising structural safety. It works synergistically with concrete slabs to steadily withstand construction loads and long-term traffic loads.

3. Flexible Long-Span Design

It supports a maximum unpropped span of 6.0m and a propped span exceeding 8.5m. Engineers can arrange girders sparsely to decrease the quantity of secondary steel components. Deflection is strictly controlled under heavy vehicles to ensure driving comfort. Fewer structural members shorten construction schedules and slash overall project costs.

4. Reliable Fire & Acoustic Performance

It achieves a 2-hour fire rating without soffit fireproof treatment, satisfying international bridge safety regulations. When matched with beam systems, it can reach 60-minute fire resistance. The composite slab also offers sound insulation, alleviating traffic noise pollution in urban areas.

5. Full Compliance with International Standards

Designed and produced in accordance with Eurocode 4, BS 5950 and AS/NZS 2327 composite steel-concrete codes. Complete technical documents and calculation formulas are provided, allowing engineers and contractors to adopt the product with full confidence in structural performance and regulatory approval.
 

Technical Parameter Table

Application Scope

• •Highway & municipal road bridges bearing heavy dynamic vehicle loads
• •Railway viaducts
• •Urban pedestrian & bicycle overpasses
• •Heavy-duty vehicle parking garages

On-Site Installation Advantages

Pre-fabricated panels enable precise assembly and rapid laying. Lightweight sheets are easy to hoist onto main girders; pre-reserved fixing holes simplify connection with steel or concrete beams. Once installed, the deck forms a secure working platform for subsequent procedures, enabling parallel construction to accelerate the whole project timeline. Its nestable structure minimizes shipping space and facilitates storage and transportation.
