Abstract
A corrosion-resistant colored 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 composition provides for both a highly corrosive-resistant coating which protects the surface of the architectural material from oxidation and also produces a gray, earth tone colored which is not highly reflective.
Claims18
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and, at least 0.01 weight percent metallic stabilizer wherein said stabilizer is a metal selected from the group consisting of bismuth and antimony.
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and a metallic stabilizer, said metal coating consists of at least 0.01 weight percent metallic stabilizer:
- ______________________________________ Tin 15.0-35.0% Zinc 65.0-85.0% Bismuth 0.0-1.7% Antimony 0.0-7.5% Iron 0.0-0.1% Lead 0.0-0.05% ______________________________________
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and a metallic stabilizer, said metal material is a stainless steel strip.
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and a metallic stabilizer, wherein said metal material is copper.
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and a metallic stabilizer, said metal material is an aluminum strip.
A coated metal material coated with a highly corrosive-resistant, two-phase tin-zinc metallic coating which upon weathering forms a low reflecting colored coating, said coating comprising at least 15 weight percent tin, at least 65 percent zinc and a metallic stabilizer, said metal material is a bronze strip.
A coated metal material coated with a corrosive-resistant, two-phase tin-zinc metallic coating which weathers to form a low reflecting gray colored coating, said coating consisting essentially of tin, zinc and a metallic stabilizer, said stabilizer content being 0.01 to 0.5 weight percent and is a metal selected from a group consisting of bismuth and antimony.
A stainless steel material coated with a strong bonding, corrosive-resistant, two-phase metallic coating which weathers to form a low reflecting gray colored coating, said coating consisting essentially of tin, zinc, a metallic stabilizer and a lead content of less than 0.05 weight percent.
A stainless steel strip with a hot-dipped alloy coating of less than 0.05 inch thickness to provide an additional corrosive-resistant surface on said stainless steel, which coating upon weathering forms a low reflecting colored surface, said alloy coating comprising a majority of zinc and at least 15 percent by weight tin.
