At ClearShield we take the threat of a knife attack very seriously… Australian Standard 5041 requires all class 3 type security door and screen products to pass the AS4483 knife attack test. This test requires our stainless steel security screen to be subjected to repetitive knife attacks without penetration of the mesh or screen greater than 150mm after three slashes of a knife.
We put ClearShield’s security screen doors to the ultimate test and contracted the services of Azuma design Testing Facility NSW (N.A.T.A accredited) to test ClearShield well beyond the standard requirements. The results were impressive to say the least!
ClearShield’s domestic grade security screen withstood over 20 cycles of the AS4483 test and still did not fail.
