Holes through the sheet must be drilled, never punched, and be 2 mm larger than the fastener diameter. We sell a 6.5 x 90mm fasteners for timber which will drill through the Profile 3 sheet, open up the oversize hole and drill into the timber purloin. They also have an integral sealing washer.
Traditional fasteners, such as M6 x 80mm drive screws for timber, can be used but only in conjunction with sealing washers and caps. Whichever fastener is selected they should be positioned on the first full corrugation to the side of the side lap. At end laps, the fasteners should be 50mm from the top end of the lap.
