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 security screens.
Prowler Proof is one of only 9 Qualicoat approved powder coating applicators in Australia, and the only security screen manufacturer product.
Qualicoat is Australia’s only licensing and audit system for the entire powder coating process on architectural aluminium. Qualicoat is an internationally recognised, 3rd party accreditation scheme for Quality Assurance in powder coating, and is audited by independent NATA approved auditors. The Qualicoat process includes tested and approved pre-treatment chemicals, powders suitable for Australian conditions and confirms the technical competencies and workmanship of the licenced applicator. The Qualicoat licensing system is used internationally in 39 countries.
The powder coating is a key element in the appearance of a security screen. The quality of the powder coating shines through – so to speak – both short term and long term. The long term benefit is superior corrosion protection – as evidenced in the fact that Prowler Proof is the only security screen to pass the acetic acid salt spray test and the only manufacturer to offer a 10 year full replacement warranty.
ForceField, Guardian and Protec, as complete screens, have passed the 1,000 hour neutral salt spray test – most manufacturers only test the mesh.
But we took it a step further. Prowler Proof ForceField and Protec have also passed the 1,000 hour acetic acid salt spray test. With a pH similar to vinegar, acetic acid salt spray is 10,000 times more acidic than neutral salt spray.
ForceField’s 316 marine grade stainless steel mesh has survived a 10,000 hour neutral salt spray test, and Guardian's stainless steel mesh has survived a 3,000 hour neutral salt spray test.
The corrosion resistance is shown through our acetic acid salt spray and neutral salt spray testing, view the results.
