TapFast® high corrosion resistant fasteners

Fixfast Ltd

TapFast® TF-HCR is a class-leading range of high corrosion resistant (HCR) fasteners designed for use in roofing and cladding projects. They have been specifically designed for use in safety critical structural applications within extreme risk corrosivity environments, such as swimming pools, or in buildings where extra durability is required. Fixfast's technical team are on hand to give you advice and support to ensure you have selected the right fastener for your project.

What is stress corrosion cracking?

Stress corrosion cracking is a type of corrosion that affects some grades of stainless steel, including austenitic, when it comes into contact with chlorine. Unlike the ‘red rust’ typical of carbon steel corrosion, stress corrosion cracking is not visible, but can have equally devastating consequences to the structural integrity of a building.

There have been well documented and catastrophic instances where load-bearing structures in swimming pools and leisure centres have collapsed due to corrosion. To prevent stress corrosion cracking, HCR fasteners are the only recommended solution for swimming pool environments.

Designed to be different

High corrosion resistant

1.4529/HCR (high corrosion resistance) stainless steel features increased levels of chromium, nickel and molybdenum. This prevents stress corrosion cracking in stainless steel caused by prolonged condensation in the presence of chlorine and acids (low pH values).

Assured performance

Designed to deliver high pull-out and shear values in even the toughest of environments.

Safety-critical applications

Specifically designed for use in safety critical structural applications.

Designed for extreme corrosivity environments

TapFast® TF-HCR includes a range of fasteners for fixing sheeting and cladding to timber, heavy steel and light steel that are suitable for use in environments with specialist corrosive characteristics including:

  • Swimming pools which experience almost permanent condensation and exposure to chlorine
  • Subtropical and tropical zones with exposure to severe humidity
  • High pollution environments such as extreme industrial areas
  • Coastal and offshore areas where there will be occasional contact with salt spray

They are also suitable for use in buildings where extra durability is required.
