RAL1004 Rebar Steel Anticorrosive Corrosion Protection pure epoxy Powder Coating
We offer various anti-corrosive options that can be used for hot flocking, fluidized bed, electrostatic and in a variety of fluoropolymers (high-build wet coatings). Epoxy powder coating is a fantastic low cost option for those looking for excellent corrosion protection while staying within the project budget. This coating is commonly used for waste treatment, water valves, and other metal coatings in both thin and heavy builds.
