Description for our service
Zinc plating is one of the most effective and widely used metal finishing processes for protecting steel and iron components against corrosion and environmental damage. By applying a protective zinc coating to the surface of metal parts, this process significantly enhances durability, extends service life, and improves overall performance in demanding industrial applications.
Our advanced zinc plating solutions are designed to deliver uniform coating thickness, excellent adhesion, and superior corrosion resistance while maintaining the dimensional accuracy of components. The protective zinc layer acts as a sacrificial barrier, preventing rust formation and safeguarding valuable parts from moisture, chemicals, and harsh operating conditions.
Widely used across automotive, engineering, electrical, hardware, fastener, and manufacturing industries, zinc plating offers a cost-effective and reliable solution for improving component longevity and maintaining product quality. With a focus on precision, consistency, and quality assurance, we provide surface finishing solutions that meet the highest industry standards and customer requirements.
Zinc Plating Capacities (per finish type)
Barrel Zinc Plating: Up to 30,000 pounds per day.
Rack Zinc Plating: Up to 70,000 square feet per day
Common Applications & Specifications of Zinc Plating
Zinc plating is widely preferred across industries due to its cost-effectiveness, excellent corrosion protection, and clean, attractive finish. It is commonly applied to nuts, bolts, washers, metal stampings, automotive components, and a variety of fabricated industrial parts. In addition to enhancing durability and appearance, zinc plating also serves as an excellent base coating for paints and other finishing treatments.
Depending on the application requirements and desired level of corrosion resistance, zinc coatings are typically applied in thicknesses ranging from 0.0001″ to 0.0005″. The most commonly used range, known as Commercial Zinc Plating, falls between 0.0001″ and 0.0003″, providing an ideal balance of protection, performance, and cost efficiency for a wide range of industrial applications.
