Zinc Plating

Zinc plating is a widely trusted method for protecting metal parts that involves applying a thin layer of zinc to either steel or iron to act as a sacrificial barrier against corrosion and wear. At Saporito Finishing Co., we’ve built our reputation on helping customers overcome common challenges, like finding parts that rust too quickly or coatings that don’t meet specifications. Our zinc plating services are designed to solve those problems with finishes that are reliable, durable, and cost-effective.

Benefits of Our Zinc Plating Services for Corrosion Resistance

Our customers turn to zinc plating when they need more than a “standard” finish. There are a variety of applications for zinc plating. These can range from automotive parts that have to survive road salt to hardware that needs a reliable finish.

Some of the advantages that zinc plating services from Saporito Finishing offer include:

Enhanced corrosion resistance. Protects against rust in demanding environments, extending product life and reducing premature part replacement.
Compliance with specifications. Meets stringent ASTM, MIL, and industry standards, ensuring your parts pass inspection the first time.
Cost efficiency. Zinc plating provides improved corrosion protection at a lower cost compared to other coatings without sacrificing quality.

From prototypes to high-volume production runs, our plating process adapts to your needs without compromising consistency.

Types of Zinc Metal Finishes We Offer

Once you decide to use zinc plating services, the next step is determining what type of zinc metal finish to choose. Below is a quick rundown of different types of zinc metal finishes you can find at Saporito Finishing all of which are trivalent, RoHS and ELV compliant.

Blue/Clear Zinc Plating

Blue or clear plating can be used with hardware, fasteners, and other components. It provides solid corrosion protection and a uniform finish at a cost-effective price point.

Yellow Zinc Plating

Known for its gold or iridescent tint, yellow zinc provides enhanced corrosion resistance and is often used in automotive and industrial parts where identification such as left from right is needed. Yellow trivalent zinc is not a good choice for parts that will require a subsequent finish such as paint, powder coating, or printing.

Black Zinc Plating

This zinc plating has a matte to semibright finish that combines enhanced corrosion resistance with an appearance ranging from slightly iridescent to pure black. This finish is commonly used in defense and military applications, and the automotive industry offering excellent protection and blending seamlessly into outdoor environments.

Our Process and Capabilities for Zinc Plating Services

We understand the importance of choosing coatings that can provide reliable corrosion resistance in the intended application. That’s why our zinc plating process is engineered for performance and repeatability.

Saporito Finishing can handle both small precision parts and large-scale production runs. First, every part is cleaned and prepped to ensure strong adhesion. Using controlled electroplating, we are able to achieve uniform coating thickness across complex geometries.

Custom post plating seals allow you to further enhance the finish, providing added corrosion resistance and coefficient of friction modification where torque tension is a concern. Our rigorous inspection and testing ensure your parts meet the highest standards for thickness, adhesion, and corrosion resistance.
