製品の説明
DX51D+Z Chromated Treatment Anti-White Rust Galvanized Steel Coil For Storage
Stop white rust before it starts. Our galvanized steel coil receives an advanced chromate passivation treatment immediately after galvanization. This critical step forms an invisible shield that actively resists moisture, providing 20-24 times better protection against white rust formation during storage and transit compared to standard galvanized steel. With a robust zinc coating (Z60-Z275) and certifications (ASTM A653, EN 10346), it guarantees your material arrives with a pristine, ready-to-use surface, even in humid environments. It's the reliable choice for warehousing and logistics where corrosion protection is non-negotiable.
