Zinc Magnesium Corrosion Protection

Enhanced corrosion resistance with Hilti's modular support system

Corrosion is a natural yet costly and potentially dangerous process that occurs in virtually all compounds. It can cause structural deficiencies that require costly repair or replacement and result in loss of time, but it’s not always easy to find compromised components until it’s too late.

Zinc magnesium offers enhanced corrosion resistance when compared to conventional zinc-coated steel, without significantly increasing the coating thickness.


A new manufacturing process is used to bind the zinc and magnesium to the bare metal surface. This results in less zinc being used, making the coating thinner, lighter, and applied more evenly throughout the components surface area compared to traditional HDG coatings. 

The thinner coating thickness also improves the forming properties of the component members, improving the mechanical properties of bends and thread deformations. This also means that even hard to reach corners, like inside bends, have better corrosion protection.
