    Frequently Asked Questions

    Crimsafe’s unique Screw-Clamp™ technology means that the mesh is screwed into the frame and clamped down with a vice like grip using the Crimsafe Screw-Clamp. This makes Crimsafe much stronger than other products that use a plastic wedge to hold the mesh in place. When hit by an impact like a kick, Crimsafe spreads the load around the whole frame and back into structure of the building, meaning Crimsafe can resist enormous impacts compared to plastic wedging systems which only localise the impact, making them relatively easy to kick out compared to Crimsafe. The mesh is also made out of 0.9mm diameter 304 structural grade wire strands, and woven together in such a tight way that each strand supports the others around it. The specifications pertaining to the mesh and other products that we supply are our target specifications. The actual specifications for items supplied may differ taking into account reasonable manufacturing tolerances.
    Unlike many other systems, Crimsafe uses a superior 0.9mm diameter 304 grade structural grade stainless steel wire in our mesh. When compared to 0.8mm 316 wire, Crimsafe Tensile-Tuff® 0.9mm 304 mesh is 26.5% thicker in cross-section, which assists its ability to absorb impact energy better at high tensile levels and makes it more appropriate for security applications. The actual strength of the stainless steel, while very important, is not the most influential factor in creating an effective security screen. The measure of how much energy can be absorbed on the way to tensile strength is far more important. Crimsafe security screens are engineered to remain strong when deformed by the impact of an attack and do not become brittle and give way. Independent testing shows that Crimsafe screens can absorb more impact than other security screen products.
    Our Tensile-Tuff® security mesh undergoes several hardening processes to make it stronger than ordinary steel of the same diameter. Our mesh is stronger than any of our current competitors’ mesh in its class. All Crimsafe products have significantly outperformed the impact levels required by Australian Standards, and can resist higher levels of impact than competitor products. Crimsafe also passes Australian Standards for jemmy testing, pull-testing and knife-shear testing.
    Yes. Crimsafe produces emergency exit window screens called Safe-S-Capes®. They allow keyless exit through windows while still maintaining heavy duty security from the outside. The Crimsafe Safe-S-Cape® can be hinged or sliding to accommodate a wide range of window styles.
    Crimsafe Ultimate has added features that increase the strength of the security screen, and also make it look better. The key differences are in the greater number of screws fastening the mesh to the frame (twice as many), and the clip-on cover that conceals the screws. This not only gives the frame a smooth, sleek appearance, it provides greater protection from intruders and also corrosion. Crimsafe Regular is five times stronger than the impact levels required by Australian Standards, and Crimsafe Ultimate is seven times stronger.
