Zinc Plating
Zinc plating, also known as cold galvanizing in the industry, which is the process of using electrolysis to form a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of the part.Compared with other metals, zinc is a relatively cheap and easily plated metal. It is a low-value anti-corrosion electroplating layer and is widely used to protect steel parts, especially to prevent atmospheric corrosion. It’s also wildly used in decoration.
What is Zinc Plating?
Zinc Plating is a widely available solution for protecting steel parts from corrosion. It is commonly chosen because it is cost-effective, offers excellent corrosion protection and features an attractive blueish/silver appearance. Zinc plating is the process of covering substrate metals (like steel and iron, etc.) with a layer or coating of zinc to protect the substrate from corrosion. There are two types of zinc plating: Hot-dip Galvanizing and Cold Galvanizing.

About the Process
Zinc plating, which is also known as galvanization, is applied to prevent the surface from oxidizing or corroding. This process is done by coating the part in a flux and dipping the part into molten zinc. The molten zinc forms a bond with the steel, creating a protective layer on the surface of the part.
Zinc plating Services
Protecting metals from corrosion by electroplating zinc is very effective, but it does require a complex process. We can provide many different types of galvanizing services for custom parts. Some of these solutions include:
- Barrel and rack plating: This process applies electroplated zinc coatings in bulk on fasteners, bolts and much more. It’s also possible to accommodate intricate or heavy parts individually on an automatic rack electroplating line.
- Acid and alkaline zinc electroplated coating: Alkaline zinc coating is effective for providing a bright finish in parts with deep recesses or inner diameters where you might need high throwing power. Acid zinc electroplated coatings are usually ideal for heat-treated steel parts.
- Conversion coatings: Trivalent and hexavalent chromium conversion coatings provide extra corrosion resistance and brighter coloring, with a number of color options for each.
