What grade stainless steel do Crimsafe use?

At first glance, one security screen made of stainless steel may look very similar to another. However, the good people at Crimsafe understand that merely using stainless steel is not sufficient to ensure the long-term safety and integrity of your home, guarding against intrusion.


That’s why they opt for a higher grade of stainless steel than their competitors. The superior long-term strength and durability of Crimsafe’s home security screens are recognised in their outstanding reputation in the industry.


In this blog, we will explain why the quality of stainless steel matters, the specific grade of stainless steel used by Crimsafe, its advantages, and more.

Why Stainless Steel Matters for Security Screens?

Stainless steel is widely accepted as the material of choice for high-quality security screens due to three main qualities:


Strength – Stainless steel offers extraordinary tensile strength, making it highly resistant to impacts and physical damage. This toughness ensures that security screens can resist break-in attempts.


Durability – Stainless steel is designed to withstand harsh environmental conditions, maintaining its structural integrity over time. This means it will not crack, warp, or degrade, making it a dependable choice for use in home and commercial settings.


Resistance to Corrosion – Stainless steel has remarkable rust and corrosion resistance characteristics. This makes it ideal for use in outdoor areas—even in high-humidity climates—with only minimal maintenance required.


These combined qualities make stainless steel the perfect material for manufacturing highly effective, long-lasting security screens. However, it’s still necessary to consider the grade of stainless steel used.

The Stainless Steel Grade Used in Crimsafe

When it comes to security screens, it’s important to get yet more granular about stainless steel quality. After all, when subjected to determined attacks, security screens must withstand a tremendous amount of beating.


So, you may ask: what grade of stainless steel does Crimsafe use?


Crimsafe use the 304 Structural Grade stainless steel for their window and door screens. It has a greater tensile strength than 316 Marine Steel, which is used by many of Crimsafe’s competitors.


The 304 stainless steel grade used by Crimsafe also has a tremendous ability to resist corrosion, rust and wear to help maintain the integrity of your home or work security systems. Crimsafe’s mesh is also 26.5 % thicker than any other mesh on the market. 

Advantages of 304-Grade Stainless Steel

Why is having security screens made of 304 Structural Grade stainless steel especially important for Australians? Many parts of Australia have harsh climatic conditions. Exposure to the elements (such as the sun, moisture from excessive rainfall and sea salt in the air) creates corrosion, rust and staining in most metal structures. 304 Structural Grade stainless steel has exceptional durability under both climatic and physical stress conditions, ensuring better long-term appearance and home protection.

How Crimsafe Uses Stainless Steel for Maximum Security

Crimsafe utilises an innovative design in their security screens, ensuring they not only protect you but also look great. Crimsafe utilises the 304-grade stainless steel mesh along with their patented Safe-SC Technology to maximise protection against forced entry.
