Method of making protected metal article
Abstract
Abstract A protected metal article is produced by combining a core of sheet steel with a protective metal consisting essentially of zinc; thereafter impressing a fibrous glass cloth into the protective metal and applying a weather-resistant outer coating applied to the fibrous glass cloth. The fibrous glass cloth may comprise either a glass fiber thread woven fabric or a bonded mat formed from randomly oriented continuous glass fiber filaments. The article is prepared by applying a molten protective metal coating consisting essentially of zinc to a steel sheet and, while the coating is in its molten condition, impressing a fibrous glass cloth into the protective metal and fusing the protective metal whereby the fibrous glass cloth is partially embedded within the protective metal.
