Technical Specifications of Custom Size ZAM Steel Coil

Custom Size ZAM Steel Coil - Galvanized Aluminum-Magnesium Alloy Coated

Custom size ZAM steel coil represents a breakthrough in corrosion-resistant steel technology, featuring a proprietary zinc-aluminum-magnesium alloy coating that delivers exceptional protection in harsh environments. This advanced coated steel product serves critical roles in automotive manufacturing, construction, and industrial applications where superior durability against corrosive elements is essential. Engineered for customers requiring tailored dimensions and enhanced performance characteristics, ZAM coils offer up to 10 times greater corrosion resistance compared to conventional galvanized steel.

What is Custom Size ZAM Steel Coil?

ZAM steel coil is a hot-dip coated steel product featuring a ternary alloy composition of zinc (Zn), aluminum (Al), and magnesium (Mg) applied to a carbon steel substrate. The coating typically contains 6% aluminum, 3% magnesium, and balance zinc, creating a microstructure that provides self-healing properties through sacrificial protection. Custom sizing capabilities allow for precise width tolerances of ±3mm and thickness ranges from 0.4mm to 3.2mm, manufactured according to JIS G3321 and equivalent international specifications.

Custom Size ZAM Steel Coil Technical Specifications

ZAM coated steel coils are produced with base metal conforming to commercial quality (CQ), drawing quality (DQ), or structural grade specifications. Coating mass ranges from Z27 (90g/m²) to Z35 (120g/m²) per side, applied through continuous hot-dip galvanizing lines at temperatures between 420-450°C. The coating exhibits a characteristic fine-grained structure with excellent adhesion strength exceeding 180° bending without delamination per ASTM A653 testing protocols.
