Coastal Projects – Choosing Corrosion-Resistant Steel Solutions

Coastal environments, with high humidity and salty air, accelerate oxidation and corrosion, significantly reducing the lifespan of steel structures. Therefore, selecting the right material is a critical factor.

🔹 Galvanized Steel (GI) vs Aluminum-Zinc Coated Steel (AZ)

• Galvanized Steel (GI): Cost-effective but offers limited corrosion resistance in salty coastal conditions

• Aluminum-Zinc Coated Steel (AZ): Features an alloy coating that provides 3–4 times better corrosion resistance, making it ideal for coastal areas

➡️ Recommendation: Prioritize AZ-coated steel for projects near the sea

🔹 Recommended Coating Thickness

• Galvanized Steel (GI): Requires higher coating (Z180–Z275) but is still not optimal for coastal environments

• Aluminum-Zinc Steel (AZ): Recommended AZ150 – AZ200+ for long-term durability

• Combine with protective paint coatings (PE/PVDF) to enhance performances

🔹 Optimal Solution

✔ Use aluminum-zinc alloy coated steel (AZ)
✔ Select coating from AZ150 and above
✔ Ensure proper installation to protect the coating layer
