Create authentic deep corrugation of a bygone era with Fielders Heritage Barrel Rolled roofing. This look is achieved by using Fielders lovingly restored 75 year old barrel press that provides the (22-24mm nominal height – ¾ inch) corrugations that cannot be achieved by modern roll-formers. Available in sheets of up to 10 feet (3.05m) S-Rib™ is perfect for centaury old buildings.
