Quality, Testing & Assurance
FIBRETAPP® is part of a fastening system supported by:
Defined manufacturing process with in-process QC checks
Testing capabilities including corrosion resistance testing, hardness testing, drill testing, PMI, and dimensional/profile checks (as shown in the catalogue QC section)
Coating solutions designed to meet corrosion resistance performance requirements aligned to international standards (ASTM / AS / BS / EN referenced in the brochure)
How to Select the Right FIBRETAPP® Screw?
Confirm the sheet material – Select the FIBRETAPP® screw specifically designed for fibre cement, fibre sheets, or similar brittle materials.
Choose the correct drill point – Ensure the drill tip and shank design allow clean penetration without cracking or chipping the sheet.
Match thickness & support – Pick the right screw length based on sheet thickness and the underlying steel or timber support.
Ensure sealing & durability – Use EPDM sealing washers and corrosion-resistant coatings for long-term weatherproof performance.
Installation guidelines (best practices)
Confirm sheet profile and choose length based on corrugated sheet height and purlin engagement requirement.
Drive the screw straight and keep washer setting controlled: secure underhead seating, do not overdrive (consistent with the brochure’s general washer-setting guidance visuals).
Use a suitable powered tool and correct drive bit/socket to maintain consistent installation torque.
