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