Prepping and Applying a 3-Coat System — Zinc Primer, Epoxy Midcoat, Urethane Topcoat

All Projects / Rohnan — 3-Coat System on Structural Steel

Rohnan, a steel fabricator, needed structural steel for a pool structure prepped and coated to a Tnemec spec. We blasted the beams and channels to SSPC-SP 6, then applied a three-coat system of zinc primer, epoxy midcoat, and urethane topcoat by airless spray, including inside the channels.
