Product Testing

We are committed to ensuring every Powell Gee component is made to the exacting standards required by our customers. Testing is a crucial part of Powell Gee’s quality assurance.

Force Tests

All our fixings have specific fastener performance values, which are the maximum forces that the fastener can withstand (measured in kilonewtons). This will ensure that project-specific specification requirements, set out by structural engineers, are complied with. Test values are available on our technical data sheets.

Pull Out Tests

These measure a fastener’s resistance to being pulled out from the substrate.

Pull Through/Over Tests

These measure a fastener’s resistance to the sheet material being pulled over its head.

Shear Tests

These measure a fastener’s resistance to lateral forces.

Tensile Tests

These measure a fastener’s resistance to medial forces. Ultimate tensile strength and breaking strength can be measured.

Torque Tests

These measure the force required to twist the fastener’s head from the body.

Corrosion Tests

All of our hex head fasteners and some of our low profiles are coated with a specialist zinc and aluminium epoxy compound. The manufacture process is environmentally sensitive as it does not use any contaminated waste product such as the Cr6 poison, unavoidable in certain galvanising/electro plating processes. Pre hardened fasteners are coated by a dip, spin, bake process with oven temperatures not exceeding 200°C. This produces a multi layered, scratch resistant coating.

Salt Spray Tests

The Salt Spray Test (DIN 50021) measures how long a fastener can resist an aggressive salt spray environment before corroding.

Our 500+ coating means our fasteners can withstand
over 500 hours in a salt spray test.

Some of our fasteners have the 1000+ coating for extreme
environments such as coastal areas and chemical plants.

Kesternich Tests

Kesternich Tests (DIN 50018) are carried out at the point of manufacture and measure how long a fastener can resist an aggressive acid-based industrial environment.
