Product Description:
Galvalume Steel Sheet is carbon steel sheet coated with aluminum-zinc
alloy by a continuous hot dip process similar to the galvanizing process. The
nominal coating composition is 55% aluminum and 45% zinc. Galvalume combines
the excellent barrier corrosion protection of aluminum with the galvanic
protection of zinc. The result is a coating that lasts a long time, a coating
that provides cut-edge protection along sheared edges, and therefore, a coating
that offers excellent protection to steel sheet. It outlasts a galvanized
coating of comparable thickness, and offers cut-edge protection that is not
available with aluminum-coated sheet.
Galvalume is recommended when a high level of corrosion resistance is very
important: Applications include pre-engineered metal buildings, industrial
roofing and siding, air-conditioning equipment, building panels, electrical
boxes, farm equipment and machinery, furnace parts, guide rails, heating equipment,
and appliances.
