What Screws Should I Use For My Sheets?
Important: Always evenly space your screw fixings across roofing sheets. Do not over-tighten or under-tighten your screws as this can affect the performance of the washer and prevent it from sealing correctly.
32/1000 sheets - Use 22mm stitching screws to fix flashings/sheets to other sheets. We recommend using TF32-S19 screws to fix the sheets on to purlins.
34/1000 sheets - Again, use 22mm stitching screws to fix flashings/sheets to other sheets. We recommend using TF32-S19 screws to fix the sheets on to purlins. Screws should be no more than 400mm apart when securing the flashing
13/3 sheets - Use 65mm BAZ TEK Screws which are self-drilling and self-sealing. When fixing your 13/3 corrugated sheeting, it's imperative they are fixed at the crest point. Colour caps can be used to match or contrast with the roof sheeting you are using. This is an effective way of hiding the silver screws from view. Stitcher screws at 22mm are advised for securing flashings in place
41/1000 sheets - We recommend using 22mm TF32-S19 screws which are self-drilling and self-sealing. Colour caps can be used to match or contrast with the roof sheeting you are using. Purlin spaces for tile sheets need to be 600mm apart.
Ridge Caps - Should be fixed using self-drilling TEK-type stitching screws. Each ridge should be overlapped by a minimum of 200mm.
For Flashings - The 22mm stitcher screws are advised for securing flashings in place. Screws should be no more than 400mm apart when securing the flashing.
