ZINC-MAGNESIUM (ZM)

1. Product Description

Zinc-Magnesium (ZM) is a high-end coated steel, featuring a 03-components GLMAG alloy coating developed by Poshaco Group. Its enhances corrosion resistance 5-7 times more than galvanized steel, making it the most cutting-edge coated steel available today. It is specifically designed to replace conventional coated steel in harsh environments.

2. Key Features & Advantages of ZAM Steel

Superior Corrosion Resistance – 5-7 times better protection than traditional galvanized steel.

Self-Healing Technology – The alloy coating quickly seals cut edges and screw holes, preventing rust.

Excellent Paint Adhesion – Ensures a strong bond between paint and coating for lasting durability.

Ideal for Coastal & Chemical Environments – Outperforms Galvalume (GL) in rust prevention.

Lower Maintenance Costs – High durability reduces the need for frequent maintenance.
