Corrosion resistance


A 1,000 hour salt spray test is a common measure for corrosion in stainless steel security products. This is equivalent to approximately 10 years environmental exposure. Crimsafe passed this test, but also passed a much tougher test - 3,000 hours in the Prohesion Accelerated cyclic test. That's equivalent to 30 years environmental exposure.

The 1,000 hour salt spray test

In the industry standard Salt Spray Test, a salt solution is sprayed at the test samples for 1000 hours, simulating 10 years of exposure to very harsh weathering conditions. (AS 2331.3.1)

The Crimsafe security screens tested passed a massive 3000 hours with no corrosion, our Tensile-Tuff® security mesh passed 10,000 hours with no corrosion.

The Prohesion Accelerated Test

Crimsafe security screens also pass the Prohesion Accelerated test (ATSM G85), which provides a better correlation with real-world outdoor exposure results.

Prohesion tests use a method of cyclic accelerated corrosion and are designed to evaluate how well the surface coatings of the Crimsafe screen protect from corrosion.

Crimsafe passed 3,000 hours with no corrosion, loss of adhesion or blistering. This is due to the unique powder coat that Crimsafe® mesh features. 

The specially developed coating, which is exclusive to Crimsafe®, contains additives that prevent the build up of impurities by making the surface slippery at a microscopic level - impurities just can't grip on. It is also very hard, which means that it does not chip off or crack and leave the stainless steel underneath exposed to the salt environment 

The coating is fully compliant with AS/NZS 4506:1998 Metal finishing-Thermoset powder coatings.

Note: Regular cleaning of your Crimsafe® screens in accordance with the warranty and care guide instructions is essential to getting the best performance out of your screens.

With regular cleaning, your screens will look great, stay strong, and beat more burglars for a lifetime.
