About United Coatings

One Company.
Every Coating Your Steel Needs.

The Northwest's true one-stop coatings shop — sandblasting, powder, paint, and duplex systems under one roof.

Our Story

Built to Be the Northwest's One-Stop Coatings Shop.

United Coatings was founded with a simple goal: give customers a true one-stop service for all their coatings needs. Fabricators and contractors were trucking steel to one shop for galvanizing, another for blasting, and a third for paint or powder — adding cost, handling damage, and days to every schedule.

Today, our 34,000+ sq ft facility in Sedro-Woolley, Washington brings it all under one roof: two sandblasting booths, the largest powder coating oven in the Pacific Northwest, a dedicated industrial paint booth, and duplex topcoat capability for galvanized steel. The result: one purchase order, one point of contact, and steel that leaves our shop ready for the field.
