Our 4″ Rib is a very popular profile that is used both as a siding and roofing panel, ideal for heavy industrial and lagging applications. The 4″ Rib is typically ordered as a Mill finish aluminum and Stucco-Embossed finish. Panels can be curved or custom rolled. The additional strength panel would come in the galvanized finish, with load tables available for all the types of material. Call for other sizes other than the .032 and .040 aluminum, and 18, 20, 22, 24 gauge galvanized finishes. Standard lengths are 6-45’.Common uses are warehouse and industrial buildings. If there is a certain material you would like your 4″ made to, please call and talk with an expert as we do form custom panels.
