Product Description

Galvanized Steel Structure Bridge

Materials and Mechanical Advantages
The structural framework utilizes steel (typically Q235 carbon steel or Q355 low alloy steel) for primary load-bearing components including main girders and piers, offering both high strength-to-weight ratio and modular construction benefits.

The corrosion protection system employs hot-dip galvanizing, where steel elements are immersed in 450-500°C molten zinc to create a ≥65μm zinc-iron alloy coating. This provides extended protection (15-20 year service life) through sacrificial anode action.

The metallurgically bonded zinc coating preferentially corrodes in aggressive environments, safeguarding the underlying steel substrate. This makes the system ideal for challenging conditions including:

High humidity areas;
Industrial pollution zones;
Coastal marine environments;
Resulting in substantially reduced lifecycle maintenance requirements.

Typical Application Scenarios
Temporary Transportation Facilities: The steel trestle bridge built quickly replaces the original bridge during the maintenance period, and the construction efficiency is more than 70% higher than that of concrete bridges.

Cable Support System : The galvanized cable tray attached to the bridge (trough/tray type) has a zinc layer to prevent corrosion and ensure the safety of power communication pipelines.

Landscape Bridges : Galvanized steel arch + cold-sprayed zinc coating is adopted, taking into account the anti-corrosion needs and streamlined aesthetic design.
