a question we get:

What are the benefits of powder coating sheet metal?

The Finishing crew at Pinnacle Precision boasts expertise in painting and powder coating sheet metal parts used by our customers in the medical, aerospace, communications, and energy industries. While painting and powder coating makes sense when finishing sheet metal, powder coating has several benefits.

Powder coating sheet metal gives parts a strong finish resistant to wear, chipping, and scratching while adding a protective layer that produces strong corrosion resistance.

These benefits alone are helpful for our clients who are building components situated in harsh environments. 

Powder coating also is a more efficient process in the finishing stage and is easier to maintain when out in the field. Plus, powder coating adds electrical insulation and chemical resistance to every part.
