PolyX PVC F Section Rafter Supported - 10mm - 3mtr - White

No, this component is specifically engineered for 10mm sheets and will not provide a secure fit on 16mm or other thicknesses.

The F Section is designed as a pressure-fit component and typically does not require screws for the trim itself, though your main glazing bars will require standard fixings.

Yes, PVC is resistant to salt air and corrosion, making it a suitable choice for exterior use in most environments.

You can cut the PVC easily using a fine-toothed hand saw or a hacksaw for clean, precise edges.

While the PVC has a finished white surface, you can use specialized plastic-bonding spray paints if you choose, though this is generally not required.

Ensure the polycarbonate sheet is not pinched by glazing bars and that the edge is clean of burrs or excess protective film.

Verify you are using genuine 10mm polycarbonate sheeting; if the fit remains loose, check if the sheet edge has been damaged or crushed during the installation of support bars.
