Advantages

Thanks to its 3% magnesium content, Zn-Al-Mg offers self-healing on cut edges and superior corrosion resistance in chloride and ammonia atmospheres.This high corrosion resistance means that less metallic coating is required (weight reduction), which facilitates processing
steps such as welding. The zinc-rich metallic coating composition permits all the conventional processing operations possible with standard
hot dip galvanised steel: bending, drawing, clinching, profiling, stamping, welding etc. The friction coefficient of Zn-Al-Mg coated steel is lower than that of standard hot dip galvanised steel, leading to reduced powdering during forming operations.
