Twinwall Roofing Fixing Screws are designed for securely fastening Twinwall polycarbonate sheets and acrylic flat sheets to timber or metal support structures. Manufactured from corrosion-resistant stainless steel and supplied with bonded sealing washers, these fixings provide a strong, weather-resistant connection while helping to prevent water ingress around fixing points.
 
Suitable for both residential and commercial roofing projects, these screws are ideal for pergolas, patios, carports, greenhouses, conservatories, and covered outdoor areas.
 
To allow for thermal expansion and contraction of the sheet, an oversized expansion hole must be drilled prior to installation.
 
Prices exclude GST.
