Lightweight, durable and highly recyclable, aluminum has been hailed as the metal of modern life for its corrosion resistance. Aluminum sheet metal is the most commonly used raw material and is used in many applications like construction and manufacturing. Aluminum from 0.008 inches to less than 0.25 inches thick is considered sheet, while thicker than 0.250 inches is considered aluminum plate and less than 0.008 inches is aluminum foil. Aluminum sheets are used in siding, automobiles and cookware. Aluminum plates are used in storage tanks and often jets or spacecraft fuel tanks. Depending on what you're using it for, find aluminum gratings, aluminum channels and aluminum tubes and aluminum treads for use with your aluminum sheets.
