Our polycarbonate roof screws can save 50% of labor time – create an expansion hole and fix sheets in one go.
Polycarbonate Roofing Fasteners
POLYXPAND™ polycarbonate roofing fasteners are designed to create a much-required thermal expansion hole on plastic roofing materials and then securely fastened onto the purlin underneath in one-go.
Owing to the wings on the drilling tip, a 10mm diameter thermal expansion hole is created during the process, which then snaps off immediately upon coming in contact with steel. A large BAZ washer completes the package, covering the expansion hole while providing superior strength against high winds.
