The Northwest's true one-stop coatings shop — sandblasting, powder, paint, and duplex systems under one roof.
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.
A comprehensive quality control system covering every production stage — from material intake to final inspection — ensures consistently high-quality results you can specify with confidence. Our QPL listing is in progress.
With decades of combined coatings and corrosion-protection expertise, our team knows steel, surface prep, and coating systems inside and out.
Dedicated booths and three acres of production space mean your schedule doesn't depend on someone else's backlog.
Full-floor media recovery, engineered ventilation, and trained operators keep our people safe and your product handled properly at every step.
We uphold a comprehensive quality control system that covers every production stage, from material intake to inspection. We work to ASTM standards, have successfully performed work on WSDOT-certified projects, and align our processes with guidance from industry organizations such as the Pacific Northwest Steel Fabricators' Association and the American Galvanizers Association.
Our Qualified Products List application is underway — the documented, repeatable quality processes it requires are already in place.
Surface preparation and coating application performed to applicable ASTM specifications.
Inspection checkpoints at intake, after blast, after coating, and before shipment — with records to match.
Every job is verified with non-destructive testing and documented at each production stage, including:
