Guardian® Corrosion

Whenever two different metals interact there's a risk of corrosion. So the fact that Prowler Proof is welded instead of being held together by screws or rivets makes it more corrosion-resistant than other screens. Guardian is one of very few complete screens that has passed the 1,000 hour neutral salt spray test – most manufacturers only test the mesh. Prowler Proof is one of only 10 Qualicoat approved powder coating applicators in Australia, and the only screen manufacturer.

Neutral salt spray test (AS 2331.3.1)

The Test

Guardian has been tested to the Australian Standard 2331 which requires the product to survive a 1,000 hour neutral salt spray test. This test is an accelerated corrosion process that takes place in an enclosed chamber. The spray is saltier than sea water and the temperature is maintained at +35ºC with almost 100% humidity.

The Result

Passed. Guardian is one of very few complete security screens that have passed the test – most manufacturers only test the mesh. Guardian's 304 stainless steel mesh has actually survived a 3,000 hour salt spray test.

Your Benefit

Prowler Proof is the most corrosion-resistant screen on the market. Quite simply because it is welded instead of being held together by screws or rivets. Whenever two different metals interact there's a risk of corrosion.
