It's because Crimsafe is the only Stainless Steel Security System on the market where the mesh is screw-clampedTM to the frame to hold it tight. We hold the patent on mechanically fastening the mesh to the frame.
When hit by an impact like a kick, our system spreads the load around the whole frame and back into structure of the building, meaning Crimsafe can resist enormous impacts.
The mesh is also made out of .9mm thick Premium 304 Grade Security wire strands, and woven together in such a tight way that each strand supports the others around it.
Crimsafe passes the Australian Standard Knife Shear Test, meaning the mesh conforms to the pass rating specified by the standard. However in real life, if you work at something long enough and if you have the right tools, you can cut just about anything.
The point to understand though is that Crimsafe is strong enough to resist attacks from the common cutting implements that burglars carry for a long, long time - certainly beyond the point where the criminals will give up out of fear of being caught in the act.
Our recommendation is not to do so. Whilst there is no difference in the strength of the mesh itself, Crimsafe's Commercial system features five times the number of screws through the mesh and the frame, and 60% thicker frames to dramatically increase the strength of the system.
Whilst the domestic system is very strong, we had to consider that in most commercial applications, it can be quite isolated and a would-be thief would have a vast amount of undisturbed time to carry out an attack on the screen. We decided that a much stronger screen would give you better protection.
Our commercial system, which was originally designed for jail and detention centre applications, was the perfect choice.
Crimsafe doors can be made without a mid-rail, however we always recommend that you get one because it greatly increases the strength of the door and its resistance to jemmying, and aids in visually identifying the presence of the door. (The last thing you want is to try to walk through a Crimsafe door in the middle of the night or brightness of the day - it could be a rude awakening - a mid-rail alerts you or your visitors to the presence of the security screen.)
If you decide you want a Crimsafe door but you don't want a mid-rail, we recommend that you ensure your new door is fitted with a special triple-locking system designed for this application, as standard throw-locks will not resist jemmying adequately without a mid-rail.
