Product Description
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.

We ensure secure delivery with VCI+PE dual-layer waterproof packaging and reinforced edge guards for optimal corrosion protection. Global shipping options are available via FOB/CIF, with project quantities delivered within 25-30 days. Each shipment includes pre-shipment inspection and moisture indicators for quality assurance.
Q1: Does chromate treatment affect welding or paint adhesion?
A1: No. Our trivalent chromium passivation provides anti-rust protection without compromising surface properties. It ensures excellent weldability and enhances paint adhesion.
Q2: What are the options for custom-cut sheets and their tolerance?
A2: We provide custom-cut sheets from 3 to 6 meters in length, with a maximum of 6 meters. All sheets are precision-cut to certified dimensional accuracy with burr-free edges.
Q3: What quality documentation is provided?
A3: Each batch comes with an EN 10204 3.1 certificate, providing full traceability and verifying chemical and mechanical properties against order specifications.
