Recommended Fastening Method

When fixing into timber battens, we recommend a 12 gauge x 65mm Type 17 Hex Head screw. If fixing into steel purlins, please use a 12 gauge x 55mm Steel Fix Hex Head screw. When using the sheets as wall cladding, a 12 gauge x 25mm Type 17 Hex Head should be used for timber battens and for steel purlins, a 10 gauge x 16mm Steel Fix Hex Head screw is best.
