Don’t Put Your Roof at Risk with Inferior Fasteners
Fasteners are a small part of the costs of the roof construction (around 2%). Choosing the wrong fastener can cause the whole roof structure to fail. These failures are usually caused by the harmful effects of corrosion.

Why Fastener Corrosion Protection is Important
Protect your most valuable asset against the harmful effects of corrosion. While the fastener you choose will be the smallest expense in putting on a roof, spending a fraction more will save you from expensive fixing costs, structural failure of the roof construction, water entry and rust that ruins the look.

Fasteners for Stainless Steel and Aluminium Sheeting
Stainless steel and aluminium sheeting are used in highly corrosive environments. For this roof sheeting, Buildex® Stainless Steel Fasteners are recommended.
Stainless Steel fasteners are not suitable for COLORBOND® or Zincalume®. Using Stainless steel screws on this type of roofing will cause the roof to corrode.
