BUILDING MATERIAL COATING

摘要

A corrosion-resistant coloured architectural material which is essentially lead free and is not highly reflective. The coating on the material is a two-phase metallic coating comprised of a large weight percentage of zinc and a relatively large weight percentage of tin. The tin-zinc coating may also include nickel. The tin-zinc-composition provides for both a highly corrosive-resistant coating which protects the surface of the architectural material from oxidation and also produces a grey, earth tone coloured which is not highly reflective.
