Dual Directional Knife Shear Testing
NSSA and Dual Directional Knife Shear Testing
The current Australian Standards only require a manufacturer to test their mesh in one direction. But here’s the problem, some mesh passes in one direction, then fails when tested at 90 degrees, because a lower quality wire is used in the weaving process in that direction. That why the National Security Screen Association created the Dual Directional Knife Shear Testing Industry Code of Practice (ICP), and why the industry is pushing for it to become the new benchmark for security screen mesh.
Prowler Proof has signed on as a participating business in the National Security Screen Association’s Dual Directional Knife Shear Testing ICP. This commitment demonstrates our dedication to meeting the industry’s most rigorous testing standards.
Both Prowler Proof ForceField and Protec meshes have already passed the dual directional knife shear test. This achievement should give homeowners confidence they’re choosing the right product to protect their family. When you select these tested screens, you’re investing in proven protection rather than marketing claims.
The NSSA provides independent verification of security screen performance, conducting annual audits of member manufacturers. Prowler Proof holds a Certificate of Compliance under the NSSA Compliance Accreditation Scheme, confirming our products meet AS 5039 requirements.
Genuine Meshtec Mesh vs Counterfeit Products
Quality mesh should meet the highest manufacturing standards and security certifications. The difference between genuine and counterfeit products often becomes apparent only when it’s too late.
Why Prowler Proof Uses Only Genuine Meshtec
Meshtec International manufactures mesh to exacting specifications, with each wire individually tested to zero major blemishes according to ISO 9044:1999 standards. This rigorous quality control ensures consistent wire diameter, surface integrity, and weave density across every product.
Prowler Proof has made a firm policy decision: we never substitute genuine Meshtec mesh with cheaper alternatives or counterfeit products. This commitment exists because inferior mesh fails—sometimes catastrophically. Counterfeit products may use 304 grade while claiming 316, employ thinner wire than specified, or feature poor powdercoating that creates corrosion points.
Woven wire mesh can be crafted from a variety of materials such as stainless steel, aluminum, copper, brass, and bronze, providing exceptional performance and durability. However, for security applications, only genuine 316 marine-grade stainless steel from reputable manufacturers like Meshtec delivers the required protection.
The risks of counterfeit mesh include premature corrosion, failure under knife attack, and compromised security at the moment of intrusion. Our customers deserve confidence that their security screens perform as promised.
