Sheet roof supplied in New Zealand is generally of a high quality, so consumers need to be confident that the screw fastening the roofing material is of the same high quality. 

 

Ramset’s Buildex Roof Zips are roofi ng screws designed and proven to exceed the requirements of standard sheet roofing. 

 

Developed by Buildex, Australasia’s most innovative manufacturer of self-drilling screws and fastenings, Roof Zips is the product of two years’ collaboration with the roof industry and extensive fi eld research by Ramset and Buildex to determine the precise requirements of a new generation of roofing fastener. 

 

The result is a revolutionary roof fastener which not only meets the needs of roofi ng contractors but also exceeds current roof fastening strength requirements. Roof Zips incorporate a range of patented features. 

 

The new head design has 10% greater surface area to hold the sealing washer more securely, reducing the problem of washer damage. 

 

The specially designed buttress thread reduces distortion when fixing to steel purlins, providing a robust connection and greater pullout strength. 

 

Unique drill point design The unique drill point design eliminates screw skidding and scratching of the roof profile, and allows for quick and easy installation in timber battens, steel purlins up to 1.9mm thick, and thin metal battens. 

 

It also does away with the need to pre-drill, even on steep pitches and lapped sections, and helps reduce the amount of swarf and “pigtail” that can cut the sealing washer. 

 

Roof Zips also incorporate the many unique features found throughout the Buildex roofing screw range, including:

HiGrip which grips the roof sheeting and prevents water entry, 

ShankGuard which protects the fastener shank from corrosion, 

Climaseal 4 Coating which meets AS3566 Class 4, and, of course, 

Peace of mind through being fully covered by the Buildex warranty. 

 

The fast, easy installation and versatility of Roof Zips, together with its multiple applications in timber and steel, is expected to significantly reduce users’ stock holdings of Buildex Tek and Type 17 screws. Soon to be released will be the newly developed 65mm Roof Zips. Roof Zips are available from Ramset Trade Centres and all major rollformers.
