Sheet Metal Accents Add Style
Homeowners frequently want special products fabricated out of sheet metal -- anything from flashings for roofing and decks and weather vanes to bird cage pans, gutters and downspouts can be made from an assortment of metals.
Popular types of sheet metal include galvenized steel, coated steel (which won't rust but is about three times more expensive than galvenized steel), stainless steel, copper, brass, aluminum and pewter.
Sheet metal comes in different thicknesses, from 16 gauge to 30 gauge, with lower numbers being thicker. Sheet metal items can be made water tight or not. Seams can be sealed with sealant (caulking) or soldered. Soldering is more durable and a bit more expensive than sealant.
Copper sheet metal will naturally change to a turquoise color after prolonged exposure to natural elements. The more salt and moisture in the air, the sooner it will change color. This does not damage or affect the strength or quality of the metal. It can be coated to retain its natural "shiny penny" color or combinations of different chemicals called "patinas" can be applied to immediately turn copper into a variety of colors, including turquoise, red, black, blue, etc.
