Screws
Info-GLOBAL manufactures self-drilling and self-tapping screws for metal roofing and cladding. The range is divided by what you are fixing into, because that decides the drill point, the thread and the length.
How the range is divided
- Roofing — fixing sheets to the roof: farmer screws into timber, stitching screws for sheet-to-sheet overlaps, flange head screws where no drill point is needed
- Industrial halls — heavier substrates: cold-formed steel structures, timber and concrete, and sandwich panels
- Wood — carpentry and distance screws for levelling battens
What is common to the range
Hardened carbon steel SAE 1022 or stainless steel, EPDM sealing washers in zinc-plated, aluminium and stainless versions, zinc coating from 12 µm. Heads can be powder coated in our own paint shop — UV-resistant polyester 50–60 µm, colour-matched to the sheeting.
Screws are covered by European Technical Assessments ETA-18/0789 and ETA-19/0586; declarations of performance are available under Files to download.
