For over two centuries, Platt Brothers & Company has been a reliable source for Zinc and Zinc Alloys. Our Zinc/Aluminum-based wire coating, Plattzinc^TM, was created to stand the test of time and can withstand harsh environmental conditions and not succumb to rust and corrosion. When thermally sprayed onto steel, the alloy produces a metallic coating incorporating the best characteristics of both metals for optimum corrosion protection.
