Can Crimsafe be cut?

• Crimsafe’s high-tensile stainless steel mesh is designed to be cut-resistant, passing stringent knife and durability tests to deliver exceptional home protection.


• Cut testing involves applying up to 35kg of force and 15kg of downward pressure using a heavy-duty trimming knife; Crimsafe passes this test under European-level standards, confirming superior resistance to forced cutting.


• Six independent strength tests, including the knife test, verify that Crimsafe doors meet and exceed safety benchmarks, ensuring long-term reliability and protection.


• Cutting Crimsafe mesh is not recommended, as it can compromise the door’s integrity and void the warranty. My Security Door instead offers custom-made Crimsafe doors with integrated Petaway pet doors for tailored solutions.


• With over 30 years of expertise, My Security Door supplies and installs genuine Crimsafe doors across Melbourne, offering customers a trusted, high-performance home security upgrade.

Crimsafe security doors are made from high-tensile stainless steel, designed to resist cutting, prying, and impact. As part of Crimsafe’s rigorous quality control, each screen undergoes multiple tests—including the official knife shear test—to ensure it can withstand attempted break-ins.

Yes, Crimsafe performs cut tests on its mesh. The cut test is carried out using a heavy-duty trimming knife. The knife is used with a force of up to 35kg and a downward pressure of 15kg. The knife is used three times to attempt a 250mm slice in the mesh. The screen only passes if it is not penetrated in a line longer than 150mm.

This test simulates attempts to cut the screen using a variety of small—to medium-sized knives—the size most commonly used by intruders.

Despite being tested against the more stringent European standard, Crimsafe mesh passes the knife test with flying colours. So if your question is ‘can you cut Crimsafe’? The answer is that it is extremely difficult.

The cut test is only one of six tests carried out on Crimsafe mesh. Crimsafe mesh passes all of these tests to the higher European standards with flying colours, so you can rest assured that your family and home are protected with Crimsafe.

The other Crimsafe tests include:

• Dynamic Impact Test – simulates forceful kicks or strikes.


• Pull Test – checks resistance to prying tools.


• Anti-Jemmy Test – measures resistance to levering attacks.


• Probe Test – ensures intruders cannot reach through gaps.


• Shear Test – tests resistance to cutting tools.

Together, these ensure Crimsafe provides industry-leading protection for your home.

Crimsafe doors are made of high-tensile stainless steel. This high-quality material is also rust—and corrosion-resistant, allowing it to maintain its integrity throughout the years and remain cut-resistant.

Occasionally, people want to cut a hole in their Crimsafe door to install a doggy door. If your question is, ‘How to cut Crimsafe mesh?’ The answer is that this is not recommended on a Crimsafe door. Not only would it be difficult to cut through the Crimsafe mesh, but it would compromise the integrity of the door and void your warranty. We advise against self-installing a pet door into your Crimsafe door.

However, at My Security Door, we do offer custom-made security doors that integrate Petaway doors. These doors are the perfect solution for balancing your security with your pets’ needs. By custom-making these doors with the pet door already integrated into the design, you can maintain the security the door offers. 

Crimsafe doors are an excellent investment in keeping your family and home safe. The high-tensile stainless steel material they are made from means they pass the Crimsafe cut test with flying colours to protect you against intruders.
