Tin and Silver Flashed Copper Bars
WHAT IS FLASHING?
Another term for “flashing” is weatherproofing. Simply, flashing is the process of plating a metal with something else. Usually, a different metal is used. This serves to protect the base metal from corrosion and oxidation. Consequently, aluminum, copper, galvanized steel, lead, silver, stainless steel, tin, and zinc are used for flashing. Historically, lead and even birch bark were two of the most popular materials used for flashing!
