Sample Specification & Installation
The sheeting shall be Trimflute type profile as manufactured by Safintra Roofing. The profile shall be roll-formed with 6 trapezoidal ribs at 203 mm, centers with a net cover of 1015 mm. The rib height shall be 26.5 mm and shall be fixed in accordance with the manufacturer's recommendations.
Safintra 0.50 mm thick, AZ 150 or Z 120, PPGI / PPGL Trimflute Profile Roof Sheeting, fixed to intermediate steel purlins at 1400 mm centers and to ridge and eaves purlins at 1300 centers, with 12 x 65 mm long class 3 metal self drilling screws at every second crest intermediate purlins and every crest eaves purlins side laps to be stiched at 500 mm centers between purlins all in accordance with manufacturers recommendations.
Trimflute is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. You can place screws for Trimflute through the crests or in the valleys. To maxi mise water tightness, always place roof screws through the crest. For walling, you may use either crest or valley fixing. Always drive the screws perpendicular to the sheeting, and in the centre of the corrugation or rib. Don't place fasteners less than 25 mm from the ends of sheets.
The edge of Trimflute with the anti-capillary groove is always the under-lap. It is generally considered good practice to use fasteners along side-laps however, when cladding is supported as indicated in purling spacings, side-lap fasteners are not usually needed for strength.
End-laps are not usually necessary because Trimflute is available in long lengths. If you want end-laps, seek advice from your nearest Safintra office on the sequence of laying and the amount of overlap. When TRIM FLUTE is laid on slopes of 5 degrees or less, cut back the corner of the under- sheet, at the downhill end of the sheet to block capillary action.
