Aluminum Gasket Clip for Polycarbonate Sheet

Size: for 12~16mm thickness

Length: 6000mm/piece

Color: Nature color of Aluminum

Application: Conector for the polycarbonate hollow sheet and solid sheet.

Polycarbonate sheets naturally move with temperature, so you will need the correct fixings to allow this to occur without issues. Polycarbonate screws will per cut a hole wide enough to allow for this expansion. This prevents the sheets from buckling. The large rubber on the screw will also seal on the sheet and stop any water from penetrating the roof. It’s important your fixings need to go through the crest of the corrugations on your sheet. You should use a (5/16”) Drill hex driver.

The frequency of screws required for corrugated and greca sheets is every 2nd crest for end purlins, every 3rd crest on the mid purlins and on Trimdek sheets use a screw on every crest. If you’re in a high wind area fix corrugated and greca sheets on every second corrugation on each purlin/ batten
