Zinc Plating
What’s Zinc Plating?
Zinc plating is an electrochemical process that applies a thin layer of zinc onto the surface of metal parts—typically steel or iron—to protect them from corrosion. This sacrificial zinc coating acts as a barrier, delaying rust formation even if the coating is scratched or damaged.
Known for being cost-effective and easy to apply, zinc plating is widely used across industries such as automotive, electronics, fasteners, and construction. It can be finished with various colors (clear, yellow, black, etc.) and can be enhanced with passivation and sealing treatments for added durability.

FAQ Of Zinc Plating
Visit our FAQ center for more questions.
What metals can be zinc plated?
Zinc plating is most commonly applied to ferrous metals like steel and iron, but it can also be applied to brass and copper under certain conditions.
How thick is the zinc coating typically?
Zinc plating usually ranges from 5 to 25 microns (0.005–0.025 mm), depending on corrosion resistance requirements and industry standards.
Does zinc plating change the dimensions of the part?
Yes, but only slightly. Since the coating is thin, the dimensional change is minimal—however, it must be taken into account for precision components or threaded parts, especially when tolerance is critical.
