Copper is typically used for gutters, downspouts, countertops, hoods, deco tops and standing seam roofs. It also comes in perforated sheets and pre-textured hammered sheets.
We stock copper in 16 oz, 20 oz, 32 oz and 48 oz; typical sheet sizes are 36″ x 120″ and 48″ x 120″. We also stock smaller width coils in 16 and 20 oz.
Copper is measured by weight, expressed in ounces per square foot. Copper develops a patina when exposed to weather – many factors affect the color and look that develop – it can be brown, green, black, and anywhere in between. Contrary to popular belief, this is not corrosion – it’s a chemical reaction. It will not affect the lifespan of your copper product – the copper will outlive you by a long shot. There are still copper roofs on buildings in Europe from several hundred years ago.
All of our copper is minimum 99.5% pure copper, ASTM B 370.
