Zinc plating is an established process suited to hardened steel base materials. It offers added protection to steel components against corrosion. The zinc creates a barrier acting as a thin, sacrificial coating, helping to prevent corrosion from reaching the steel surface of the component beneath.
Zinc is a widely available material and depending on the application and quantity, it can be a cost-effective option for businesses on a budget when used as an alternative to stainless steel.
Stainless steel is generally more expensive than a zinc plated option, due to the chromium content of stainless steel. However, the benefits of a cheaper alternative would need to be considered against the strength and corrosion resistance of stainless steel.
Aesthetically, zinc plating produces a bright finish and superior appearance to an uncoated steel component - which is an important factor if the fastener is going to be visible within the intended application.
