DX51D+Z Anti-Rust Galvanized Steel Coil for Infrastructure
November 26, 2025
A new solution has emerged for infrastructure projects requiring exceptional corrosion protection: the DX51D+Z Anti-Rust Galvanized Steel Coil from HuiYi-GI. This specialized steel product addresses the challenges of modern construction in demanding environments, offering advanced technical specifications tailored for long-term structural applications.
The steel coil incorporates a Trivalent Chromium Passivation surface treatment that meets RoHS/REACH environmental standards. This manufacturing process creates a dense protective layer that effectively prevents white rust formation during outdoor storage or pre-construction phases. With demonstrated salt spray resistance of up to 1,200 hours (ASTM B117), the material maintains its structural integrity in coastal regions and high-humidity conditions.
Certified to ASTM A653 and EN 10346 international standards, the product provides a zinc coating range of Z100-Z275 (100-275g/m²) and accommodates various project requirements with thickness options from 0.12mm to 2.0mm. The coil's surface properties ensure optimal adhesion for subsequent painting or powder coating processes, while its anti-white rust guarantee covers 6-12 months in humid storage environments.
For transportation and storage protection, we utilizes VCI kraft paper combined with PE film packaging and reinforced edge guards. We facilitates global procurement through FOB/CIF terms, with project-scale deliveries completed within 25-30 days. All shipments include EN 10204 3.1 certification, ensuring material traceability and compliance with international infrastructure project specifications.
This steel coil represents a practical advancement in corrosion-resistant building materials, offering reliable performance for bridges, power transmission infrastructure, highway systems, and public utility applications where durability and long service life are essential requirements.
