Products / TR 5

TR 5 is an exposed-fastener steel profile for roofing and siding with double ribs 1/2 inch high at 7.19 inch centres, formed from 36 inch coil to a 30 inch covering width, with a 24 inch minimum length. It is offered in 26, 28 and 30 gauge steel, plus a 25 gauge (AL) option, in galvanized Z275 (G90), Galvalume Plus AZM150 and prepainted Perspectra Plus finishes. Duchesne describes it as the only double-rib profile in its range and lists it for residential and agricultural projects, including low-slope and long-span roofs. Duchesne's roof load-table notes state the steel conforms to ASTM A653/A653M or A792/A792M.
