Wovar's corrugated sheet screws are only suitable for mounting roof tile sheets or corrugated sheets on wooden substructures. If you still need to build the wooden substructure, we recommend using our carriage bolts, coach screws, or construction lag screws.
It is necessary to pre-drill in your roof tile sheets or corrugated sheets. Do you use metal roof tile sheets or corrugated sheets? Then, when using our metal roofing screws 4.5mm thick, pre-drill with a 5.5mm or 6mm thick metal drill bit. We recommend our 5.5 mm thick Wovar hardwood drill bit for plastic corrugated sheets. When using our metal roofing screws, pre-drill 7 mm thick with a 9 mm thick metal drill bit in metal corrugated sheets. Our 8 mm thick hardwood drill bit is sufficient for corrugated plastic sheets.
Leakages, a Thing of the Past with Wovar's Corrugated Sheet Screws
The high-quality EPDM sealing ring ensures that the mounting holes are well protected against leakage. The self-drilling metal roofing screws from Wovar are easy to mount thanks to the Torx 20 drive. Unlike our galvanized roof tile screws, our metal roofing screws are made of stainless steel A2 steel. This ensures that the metal roofing screws do not rust and have an extremely long service life. Do you want extra protection for the screw head? Then choose our metal roofing screw with cap. When installing corrugated iron, a bit of predrilling is a must, so the plastic has room to work.
What Length of Metal Roofing Screws Should I Choose?
The length of the metal roofing screws depends on the height of the corrugation. It is important that the metal roofing screws have sufficient adhesion in the wooden sub-construction. 2 or 3 cm is sufficient. Do you install corrugated sheets with a wave height of 3 cm? Then choose our metal roofing screws stainless steel 4.5 x 50 mm. If in doubt about roof construction screws, you can always call or email one of our Wovar screw specialists.
How Many Metal Roofing Screws to Use?
It is important that you are not too economical when mounting your corrugated sheets. At the top and bottom of the corrugated sheet, mount a metal roofing screw at every corrugation height. In between, 1 metal roofing screw per 3 wave heights is sufficient.
