Superior Screw and Cladding Compatibility

Our coating procedure ensures superior compatibility between fastener coating and roof sheet which helps ensure the fastener does not cause corrosion of the roof, so you avoid expensive rectification costs.

Help prevent under roof corrosion

Under roof corrosion of roofing screws is the great hidden danger. Our ZAP Fastener shank protection feature minimises the coating removed from the screw during installation, ensuring maximum protection from corrosion. The shank protection feature (see picture below) enlarges the hole making it larger than the screw shank following behind so that the protective coating is not scraped off when passing through the roof profile.
