Screws for roof tiles

Self-tapping screws measuring 4.8×35 mm are used to fasten the metal sheets; they feature an EPDM rubber gasket that is resistant to temperature fluctuations and solar radiation, ensuring a tight seal. The metal sheets are joined together using 4.8×19 self-tapping screws. The screws should be driven using a screwdriver equipped with variable power control, at the lowest point of the roof tile’s wave or at the bottom of the trapezoidal sheet’s wave.

The estimated number of screws required is 6–8 per square meter of roof surface and depends on the shape of the roof and the number of Flashings.
