The “before” example shows the raw welds, and to the right of that piece is the finished product after polishing to the customer’s specification. This is a manual polishing process.

The “brushed” finish is both extremely durable, non-marking, and aesthetically pleasing.


Application-by-Industry

Electrical Hardware and Equipment Manufacturers


Our electrical hardware manufacturing customers use a wide variety of metal finishes on:

  • electrical boxes,
  • covers,
  • panels,
  • faceplates for high-end stereo and test equipment,
  • mounting hardware and more

–to enhance durability, corrosion resistance, and aesthetic appeal.

Zinc Plating

Common finishes include zinc plating on steel, which provides excellent protection against rust and corrosion and provides a superior base for paint and powder-coated finishes. Zinc chromate provides an excellent finish for steel mounting and base plates.

Passivation for Stainless

Stainless steel is also popular for its strength and resistance to tarnishing, making it ideal for harsh industrial environments and outdoors. Electropolishing or passivation of stainless will greatly add to its weather durability.

Additionally, anodized aluminum is used for its lightweight properties and resistance to wear and corrosion. These finishes not only extend the lifespan of components, such as control panels, but also ensure they meet safety standards and blend seamlessly into various settings.

Anodizing of Aluminum

Anodizing is also highly decorative, providing a luxurious shiny or satin finish usually seen on faceplates of consumer electronics. High end stereo equipment and amplifiers tend to use these durable, aesthetic finishes. Often, these are black or gold anodized finishes, but other colors are available.

Reliable Plating has finished thousands of components and enclosures for electrical manufacturing companies. We also work with electrical engineering firms to copper plate items (usually brass) to increase their conductivity for certain electric-carrying applications on items such as buss bars and other electrical contacts.

Reliable Plating can handle hundreds, or thousands, of your parts every month while maintaining quality, and competitive volume pricing all while ensuring your products meet the highest industry standards.
