Chosing the Correct Class of Fastener:

It is imperative when using superior corrosion resistant steel roofing, walling and accessory materials that the performance of the fasteners used to fix these materials have the same or superior service life. Specifying the correct fastener for these projects is critical for long term performance and aesthetics. The Fixtite Fastener Application Guide table gives a general guide to the fastener metal type recommended for various Safintra steel roofing products. In th e interest of q uality assurance it is essential that fasteners used comply with the South African National Standard SANS 1273:2011.

Fastener Types:

There are two fastener designs to be considered for use with Safintra’s materials.

• Fixtite Self-drilling screws for fastening cladding to a building structure and

• Accessory fasteners for fastening roofing accessory items such as flashings.

Where accessory fasteners such as pop rivets are required, they should be manufactured from Aluminium when fastening Aluminium-Zinc coated steel. In the case of Stainless Steel, compatible stainless steel pop rivets must be used.

Compatibility:

Fasteners containing elements of Stainless steel, Lead, Copper, and copper containing alloys (such as MONEL) should not be used in conjunction with Aluminium-Zinc or pre-painted steel.

 

Washers used with Fasteners:

The rubber washer component of self-drilling screws must be manufactured from materials compatible with the roofing material.

Washers containing significant levels of conductive carbon black fillers are NOT suitable for use with Aluminium-Zinc alloy coated and pre-painted Aluminium-Zinc coated products, particularly in marine environments. Therefore fasteners must be assembled with carbon-black-free washers.

 

Shank Corrosion:

In certain applications the fastener may be exposed to a greater risk of corrosion as a result of specific environments (e.g. high condensation and specific service environments such as intensive animal farming). Under the South African National Standards, corrosion classification is based on the fastener heads rather than the shanks. Please consult Safintra regarding shank corrosion within the specific application area of each project.
