Technically, yes—but it’s not the go-to solution for plumbing systems. Powder coating is more commonly used for exterior metal surfaces in industrial or decorative applications. If you’re looking to reinforce the interior of galvanized pipes, epoxy coatings or polyurea pipe coatings offer a far more effective and long-lasting result. At Radiant, we’ll help you choose the right coating based on your specific plumbing needs.
