Aluminium or Stainless Steel: Which Material Should You Choose For Your Security Mesh?

When choosing security meshes for your doors, you have to check for features that make the security mesh stand out. One of the things to consider is the material used to make the security mesh. While aluminium and stainless steel are both strong and durable metals, they have some differences. The following is a deeper look into the two materials.


Generally, stainless steel is more expensive than aluminium because of the raw materials used to make it. Aluminium is extracted from a natural rock called bauxite via electrolysis. Stainless steel, on the other hand, is an alloy made by several components including nickel, carbon and molybdenum. This is why stainless steel security meshes will be more expensive than aluminium ones.

Strength and durability

Stainless steel is a stronger metal than aluminium. It is more resistant to external damage such as scratching, chipping, denting and bending. For this reason, security meshes made from stainless steel will last a longer time than aluminium. This is not to say that aluminium is an inferior metal. Aluminium can last decades before needing any repair as well. Stainless steel just happens to be more durable because of its composition.

Resistance to Corrosion

Stainless steel is known to be extremely resistant to corrosion. This is because of its unreactive nature. For example, if there was a fire accident, stainless steel security mesh will experience less damage as compared to aluminium meshes. Both aluminium and stainless steel do not rust .


Aluminium is a more flexible metal as compared to stainless steel. Therefore, in the case of door security meshes, aluminium will offer more variety in terms of design. You will be able to easily get aluminium security meshes which fit your aesthetic preferences, as opposed to stainless steel meshes.


As seen earlier on in this article, stainless steel is made from a combination of several elements. Naturally, this will make stainless steel a heavier metal. You will therefore notice that any security mesh made from stainless steel is heavier than that of aluminium. This can be experienced especially if the security mesh has been installed on sliding security doors. The energy you will require to open sliding security doors that have stainless steel security meshes will be significantly higher. The weight difference can also make it easier to install aluminium security meshes as opposed to stainless steel ones.
