Aluminum Deep Corrugated Sheets are available in two nominal corrugation profiles, with bare or painted exterior surface, and in smooth or stucco embossed surface finishes. The corrugation profiles are engineered to provide strength and stiffness superior to that of standard aluminum jacketing. Aluminum Deep Corrugated Sheets are a premier protective outer surface for mechanical insulation systems on flat surfaces, large equipment, towers, vessels, and vertical cylindrical tanks with an outer diameter larger than 8 ft. Aluminum Deep Corrugated Sheets help protect the insulation and underlying surface from physical damage, UV exposure, corrosive environments, and water.
