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.
Common Questions
Weldability:
Zinc Magnesium (ZM) exhibits enhanced weldability due to its thinner coating.
The welding processes employed for ZM are identical to those used for zinc-coated materials.
Consistent welding consumables, procedures, and guidelines can be implemented.
ZM provides superior corrosion resistance for re-protected welded areas compared to post-galvanised coatings.
It delivers exceptional corrosion resistance, surpassing that of other metallic-coated steels.
Formability:
Friction test results indicate that ZM outperforms hot dip galvanised steel.
Steel components coated with ZM are easy to process without damaging tools.
ZM allows for the deformation of steel without the application of lubricants.
