Introduction

Zinc Aluminum Magnesium Coated Steel is a new generation of revolutionary alloy-coated steel. As a professional Zinc Aluminum Magnesium factory, we produce high-quality ZAM coils that combine Zinc, Aluminum (5-11%), and Magnesium (3%).

The addition of Magnesium creates a stable, dense protective layer (Simonkolleite), providing the steel with "Self-healing" capabilities.

Key Advantages

Superior Corrosion Resistance: Lasts significantly longer in salt spray tests (2000h+).

Unique Self-Healing Effect: When cut or scratched, the magnesium-rich coating migrates to protect the exposed edge.

Alkaline Resistance: Ideal for livestock buildings and harsh industrial environments.

Cost-Efficiency: A perfect, lower-cost alternative to stainless steel or aluminum in many applications.

Excellent Formability: The coating is harder and more resistant to galling during stamping and bending.
