Fielders Steel Roofing now has a newly restored 75 year old barrel press that is able to create the authentic deep corrugations (22-24mm nominal height - 3/4") of bygone eras. This authentic profile can be used on heritage projects where the corrugations (16mm) that modern rollformers produce would not be suitable. Called '3/4" Corrugated', this exciting profile is available in short sheets up to 10 feet in length that perfectly match those on century-old buildings.
