Zinc Plating as an anti-corrosion solution
Zinc plating is a sacrificial coating which prevents corrosion on steel substrates. It is widely used in many industries and provides a cost effective finish with good levels of corrosion protection.
The zinc layer is further enhanced with a range of Trivalent passivates which enhance the corrosion resistance of the plated layer. These are available in a range of colours;- clear, yellow, olive drab and black).
Zinc Plating and Passivate
The passivate films offer protection to the zinc plating layer and prevent the formation of zinc oxide (white rust). The zinc offers sacrificial protection by corroding in preference to the steel substrate beneath it and prevents the formation of unsightly iron oxide (red rust).
Key Properties of Zinc Plating
- Corrosion Protection
- Typical rack plated component with colour passivate - 96 hours to white corrosion
- Low cost
- Abrasion resistance
