Description
Viaduct Bridge Humid Corrosion Guardrail | Hot-Dip Galvanized Highway Safety Barrier for Elevated Roadways
Product Overview

This viaduct bridge guardrail system is engineered for elevated highways and overpass structures operating in high-humidity environments. Manufactured from Q235 carbon structural steel with full hot-dip galvanization, it ensures long-term structural integrity and corrosion resistance in moisture-intensive conditions such as urban viaducts and coastal transport corridors.

Cause

Bridge structures exposed to humid air and temperature fluctuations suffer from accelerated oxidation, coating degradation, and reduced service life of steel components.

Solution

The hot-dip galvanized coating forms a dense zinc-iron alloy layer, providing electrochemical protection and significantly reducing corrosion risk in long-term humid exposure.

Specifications
Item Specification
Material Q235 carbon structural steel
Surface Treatment Hot-dip galvanizing
Zinc Coating Thickness ≥ 85μm (customizable)
Standard EN 1317 / ASTM A123
Beam Type Thrie-beam / W-beam optional
Service Life 20–30 years
Application
  • Urban viaduct systems
  • Elevated highway ramps
  • Metropolitan ring roads
  • Multi-layer transportation bridges
How it Works

The galvanized zinc layer acts as a sacrificial anode, corroding first to protect the steel substrate, ensuring long-term structural safety even under continuous humidity exposure.

How to Choose
  • Select thicker zinc coating for coastal or high rainfall regions
  • Choose thrie-beam for high-impact traffic corridors
  • Confirm compliance with local highway safety standards
FAQ

Q1: Is this suitable for coastal viaducts?
Yes, it is designed for high humidity and salt-laden environments.

Q2: What is the minimum zinc thickness?
Standard is ≥85μm, higher coatings are available.

Q3: Can it be customized?
Yes, beam type, height, and coating can be customized.

Q4: What is the service life?
Typically 20–30 years depending on environment.

Q5: Does it meet EU standards?
Yes, it can be manufactured to EN 1317 requirements.
