The only true assurance for protection against our corrosive coastline, fall out and emissions from industrial stacks, salt and other chemically polluted environments.

Buildex Stainless Steel screws conform to the new Australian standards for fasteners AS3566.2, which states that screws should be inherently corrosion resistant.

Used in conjunction with sheeting & cladding manufacturer’s guidelines Buildex offers you a variety of Stainless Steel screws suitable for use in metal, timber and aluminium host materials.

No other Australian screw manufacturer can offer the full variety of Stainless Steel screws required to meet with today’s environmental, structural and aesthetic requirements.

Product Range

For a number of years Buildex has been the leading Australian manufacturer of Stainless Steel Taptites and Type 17 screws. Recently, Buildex have released a new range of Stainless Steel Teks® self drilling screws for roofing and cladding applications.

This new range leads the way again, with the innovation of robotically welding a martensitic drill tip to its 300 Teks. This hardened tip provides the drill performance benifits of a carbon steel tip, while providing higher corrosion protection. It allows the grade 305 body of the screw to secure materials being fastened with a more ductile grade of stainless steel.

More Information

Since March 1999 Buildex in conjunction with some of Australia’s leading sheeting & cladding material manufacturers have set up a specific program to test Stainless Steel and Class 4 screws in various materials.
 
The severe conditions encountered at both King Island and Newcastle sites have given Buildex the ideal testing grounds for Stainless Steel screws installed into various materials.

Stainless corrugated sheeting attached to galvanised beams on an open test rig at Newcastle. Screws used Stainless Teks® and Taptites in grade 304 and 316. Test period 16 months. All Buildex screws show no structural failures.

Ampelite Webglas GC® sheeting attached to galvanised beams on a sheltered test rig at our Newcastle site. Taptite screw in Stainless grade 304, 316 and Martensitic self-drilling screws, all parts were assembled with stainless plates and EPDM washers. Test period was 30 months.
Results from this test and actual job site use of Martensitic screws have made us aware of hardness problems when using these products in crest fixing applications. The instances of failure experienced were all related to fatigue situations where the crest fix fastener was subject to repeated bending as the roof sheet expanded and contracted.

Aluminium sheeting and purlins on a sheltered test rig at our King Island site. Purpose of this test was to measure the relative corrosion performance of Stainless and other coated screws when used in Aluminium. Test period 44 months.
Results obtained confirm the use of Buildex Stainless 304-316 series as the best solution for this sheeting system.
