Zinc Magnesium
What is Zinc Magnesium (ZM)?
Zinc Magnesium (ZM) is a cutting-edge anti-corrosion coating that offers exceptional protection against corrosion. This innovative coating is a notable advancement over traditional Hot-Dip Galvanizing (HDG).
The ZM coating comprises 93.5% zinc, aluminium (3.5%) and magnesium (3%) formulated to create a corrosion-resistant, self-healing protective layer. Thanks to its 3% magnesium content, this protective layer is designed to withstand the harshest conditions, ensuring long-term performance, and making it a cost-effective solution.
This high corrosion resistance means less metallic coating is required (weight reduction), which also facilitates processing steps such as welding.
Main Advantages:
Self-Healing Capability
Exceptional Corrosion Resistance
Lightweight Design for Easier Handling
Eco-Friendly & Sustainable
Long-Term Cost Efficiency
ZM Properties
The unique composition allows for better performance in harsh environments, making it ideal for various applications where durability is key.
Its ability to form a sturdy, long-lasting barrier under challenging conditions underscores its superiority over conventional zinc coatings, making it an invaluable material in industries like construction, data centres, automotive, and infrastructure that demand high-performance, long-lasting protective solutions.
ZM Coating Weight and Typical Thickness
Self-Healing Effect
Initial exposure period (up to several weeks)The exposed cut end of the substrate is oxidised and forms red rust.
When subjected to rain and condensation (beyond several weeks *).
The zinc-based film containing the magnesium on the coating layer migrates over the cut end.
Long exposure period (after more than a year)
Disappearance of red rust and the increase of white rust.
The speed of the self-healing may depend on the environment.
