Viaduct Riverside Bridge Guardrail Anti Humidity Corrosion Bridge Pedestrian

Product Specification

bridge guardrail for viaduct and riverside bridge, anti-humidity corrosion

Bridge guardrail is made of Q235 carbon structural steel with full hot-dip galvanizing. The zinc thickness complies with anti-corrosion standards for highway metal parts, suitable for humid and waterside working conditions of bridge decks, river-crossing bridges and viaduct ramps.

Protection

Bridge guardrail is manufactured from Q235 carbon structural steel with a full hot-dip galvanizing surface treatment to provide long-term corrosion protection for outdoor infrastructure applications. The galvanized zinc coating complies with highway metal component anti-corrosion requirements, making it suitable for harsh environments including humid areas, waterside locations, and regions with frequent rainfall.

Designed for bridge decks, river-crossing bridges, viaduct ramps, and elevated road structures, this steel bridge guardrail provides reliable vehicle containment and roadside safety protection. The strong steel structure helps improve impact resistance, while the galvanized surface enhances durability against moisture, oxidation, and environmental corrosion.

Kejulixin supplies bridge guardrail systems for global road construction projects, highway contractors, engineering companies, and infrastructure distributors. Customized dimensions, connection designs, steel specifications, and surface treatment options are available according to project requirements.

Product Features

1. High Strength Q235 Carbon Steel Structure

The bridge guardrail adopts Q235 carbon structural steel, which offers a good balance of strength, toughness, and weldability. The material is suitable for large-scale highway and bridge safety protection projects.

Key advantages:

• Strong mechanical performance
• Stable structural support
• Suitable for outdoor infrastructure applications
• Compatible with standard bridge guardrail components
• Supports customized engineering requirements

2. Full Hot-Dip Galvanized Anti-Corrosion Protection

The complete hot-dip galvanizing process covers the steel surface with a uniform zinc protective layer, helping prevent rust caused by rainwater, humidity, and long-term outdoor exposure.

The galvanized coating provides:

• Improved corrosion resistance
• Better performance in humid environments
• Reduced maintenance frequency
• Extended service life for bridge structures

This surface treatment is especially suitable for bridges located near rivers, lakes, coastal areas, and other high-moisture environments.

3. Designed for Bridge and Elevated Road Applications

Bridge guardrails are engineered to meet the safety requirements of different transportation structures, including:

• Bridge decks
• River-crossing bridges
• Viaduct ramps
• Highway overpasses
• Elevated roads
• Urban transportation infrastructure

The guardrail system helps reduce vehicle departure risks while providing continuous roadside protection.

Technical Specifications

Dimensions, steel grades, galvanizing thickness, and installation accessories can be customized according to different project standards.

Applications

Bridge Deck Safety Barrier

Bridge decks require durable safety barriers due to limited roadside space and higher vehicle safety requirements. The galvanized bridge guardrail provides continuous protection along bridge edges.

River Crossing Bridge Protection

For bridges located over rivers and waterways, corrosion resistance is a critical requirement. Hot-dip galvanized steel guardrails help maintain structural performance under long-term moisture exposure.

Viaduct and Highway Ramp Protection

Viaduct ramps and elevated roads require reliable vehicle containment systems. The Q235 steel structure provides stable protection for high-traffic transportation environments.
