Our Sheet Metal Finishing Capabilities

Powder Coating

The most popular finish for steel and aluminum sheet metal. It provides a very durable, scratch-resistant, and corrosion-resistant finish in a huge range of colors and textures.

Anodizing (Aluminum)

Creates a hard, protective ceramic layer on aluminum parts. Black anodizing is common for faceplates, while clear anodizing preserves the metal's natural look while adding protection.

Plating

We can apply a range of plated finishes to steel and aluminum parts, such as zinc plating for corrosion resistance on steel or nickel plating for a bright, durable finish.

Silk Screening

After painting or powder coating, we can apply durable silk-screened graphics, logos, and text to your faceplates and enclosures for a professional, finished look.

Edge and Weld Finishing

A high-quality finish requires high-quality preparation.

  • Deburring & Edge Graining: All parts are deburred to remove sharp edges after laser cutting. For parts that will receive a clear finish, we can apply a directional grain (brushed finish) for a premium cosmetic look.
  • Weld Grinding: For welded assemblies that require a seamless appearance, we can grind the weld beads smooth and flush with the parent material before the final finish (like powder coating) is applied.

Sheet Metal Finishing FAQ

What is the most durable finish for a steel part?

Powder coating is generally the most durable and cost-effective finish for steel parts. It provides excellent resistance to chipping, scratching, and corrosion, and is available in a wide variety of colors.

Does the finish affect the dimensions of my part?

Yes. Powder coating is a thick finish and can add 0.05 - 0.15 mm per side. Anodizing is thinner but still adds thickness. You must account for this in your design, especially for parts that fit together. We can mask features like holes to keep them free of coating.
