제품 설명
Engineered for demanding infrastructure applications, our DX51D+Z Anti-Rust Galvanized Steel Coil delivers exceptional corrosion resistance through a specialized chromate passivation process. The treatment forms a dense protective barrier that prevents white rust formation during outdoor storage and pre-construction phases.
With zinc coating grades Z90-Z275 and salt spray resistance up to 1,200 hours, this coil maintains structural integrity in coastal and high-humidity environments. Certified to ASTM A653 and EN 10346 standards, it features enhanced adhesion properties for subsequent painting or powder coating processes. Ideal for bridges, transmission towers, and highway guardrails where long-term corrosion protection is critical.
