From our 34,000+ sq ft facility in Sedro-Woolley, Washington, United Coatings delivers one-stop surface finishing for steel fabricators, contractors, and manufacturers.
United Coatings was built to give customers a true one-stop service — blast, coat, cure, and ship, all under one roof.
Two dedicated blast booths — including a 65' booth with full-floor media recovery — remove rust, mill scale, old coatings, and steel imperfections to give every coating the surface prep it needs to last.
Learn More →Superior durability and chip resistance, vibrant long-lasting color, and enhanced corrosion protection — cured in the Northwest's largest powder coating oven at 65 feet.
Learn More →Zinc-rich primers, high-solids epoxies, urethanes, enamels, non-skid coatings, and acrylic/latex systems — heavy-duty protection for the harshest environments.
Learn More →Already galvanized? We sweep blast and apply powder or paint topcoats over hot-dip galvanized steel — the corrosion protection of zinc with the finish your project deserves.
Learn More →Shop-applied fire-resistive coatings that expand under fire into an insulating char — rated protection for structural steel with a clean, paint-like finish.
Learn More →Beams, trusses, guardrail, and fabricated assemblies finished to spec and returned on schedule.
Specialized bridge and highway coatings deliver superior corrosion resistance, extending the life and safety of public infrastructure.
Vibrant, weather- and UV-resistant finishes for signage, site furnishings, and architectural metalwork that need to look good for decades.
