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.

Abstract: A corrosion-resistant, environmentally-safe gasoline tank for motor vehicles, wherein the components of the gasoline tank are made of a metal material having a hot-dipped coating of zinc-tin applied to the exposed surfaces of the metal material. The tin-zinc coating includes at least 15 weight percent tin and at least 7 weight percent zinc. The tin-zinc alloy may also include metal additives such as nickel, antimony and/or bismuth.

Abstract: A colored, corrosion resistant architectural material having improved corrosion-resistant properties wherein the material includes stainless steel which is coated with a tin and the tin coated material is post-treated with an oxidizing solution to remove the tin coating to expose a barrier which includes an alloy of chromium, iron and tin. The barrier exhibits excellent corrosion resistance especially with respect to chlorine and has a dark grey or earth tone grey color.

Abstract: A weather-resistant strip roofing material having improved corrosion-resistant properties includes a strip of stainless steel which is pre-treated by an aggressive pickling process and/or a chemical activating process prior to applying a hot-dip tin coating, The pre-treatment of the stainless steel strip produces superior alloying between the stainless steel and the tin coating which reduces flaking of the tin coating.

Abstract: Various metal coatings have been used for many years to inhibit oxidation of metals exposed to the natural elements of the atmosphere over a period of time. Terne alloy coatings which normally contain about 20% tin and about 80% lead are some of the most popular metal coating treatments to resist corrosion. The special formulation of the present invention reformulates the terne coating to constitute a tin and lead based coating where tin constitutes at least 90% of the terne and lead amounts to less than 0.1% and preferably less than 0.05% of the terne. The low lead terne coating may also include antimony and bismuth to provide strength and hardness to the low lead terne formulation having corrosion resistive qualities similar to that of standard terne coating formulations.

Abstract: A copper metal roofing system coated with a highly corrosive resistant material is disclosed which can be used to collect potable water. The copper roofing system is highly malleable allowing on site formation of the copper roofing materials into a variety of simple and complex shapes. The highly corrosion resistant coating is a metal alloy consisting of at least 90 weight percent tin and not more than 1.0 weight percent lead.

Abstract: A method and system for applying a water gathering and channeling roof covering onto the upper roof of a building, which roof is at least slightly pitched, wherein fully annealed sheets of at least 99% titanium with a thickness of less than 0.020 inches are preformed into roof pans with right hand and left hand edges thereof formed into matching, longitudinally extending standing seam elements. The pans are placed in adjacent, abutting relatinship with one another and joined together by press fitting adjacent standing seam elements into a standing seam extending along the roof's pitch and forming a water collecting trough for gathering potable rain water.

Abstract: A method of treating a terne coating to accelerate the patina on the terne coating. The terne coated metal is coated with a specially formulated asphalt based paint which produces a semi-transparent or translucent, dull finish on the terne coated metal. The coated terne coated metal is then exposed to the natural atmospheric elements for at least six months wherein such time enhanced oxidation of lead and tin occurs.
