Galvalume Steel Sheet
Galvalume steel plate is a kind of aluminum-zinc alloy steel plate developed by Bethlehem Steel Company of the United States. Plating consists of 55% Aluminum, 43.4% Zinc and 1.6% Silicon. By adding zinc-coated (galvanized protection) to the long-term durability and heat resistance of aluminum, galvalume steel is about three to six times more durable than galvanized steel (both 270 g/m2) under all conditions of use.
