Z275 Heavy Coated Galvanized Steel Coil For Coastal Guardrails
Our Z275 Heavy Coated Galvanized Steel Coil is engineered for coastal guardrails, where chlorides, road salts, and ocean mist accelerate corrosion. Through continuous hot-dip galvanizing at ~450°C, the Z275 coating (275 g/m² double‑sided, ~20µm per side) provides dual‑phase protection: a physical barrier and sacrificial zinc protection that even protects cut edges. Under ASTM B117 salt spray testing, Z275 typically resists white rust for 1,000+ hours and red rust for over 1,500 hours (vs. 500‑800 hours for Z120), with some products passing 3,000 hours. This yields 20‑25 years of maintenance‑free service, making Z275 the preferred choice for AASHTO M180‑compliant coastal guardrails.

Main Applications

· Coastal Guardrail Systems: Primary material for W‑beam and Thrie‑beam guardrails, transition sections, end terminals, and crash barriers along coastal highways where exposure to salt spray, high humidity, and de‑icing chemicals accelerates corrosion .

· Bridge Railings & Parapets: Safety barriers on bridges and overpasses exposed to splashing seawater, road salts, and splashback from passing vehicles.

· Highway Signage Gantries & Structural Supports: Overhead sign structures and roadside poles where structural integrity must withstand both corrosion and traffic pollution .

· Noise Barriers & Wind Shields: Steel panel systems installed in coastal corridors requiring heavy‑duty corrosion protection against salt‑laden winds .
