What is the rust resistance of expanded metal mesh?

Expanded metal mesh can rust, depending on the type of metal used and its exposure to moisture and environmental conditions. Here’s how it varies by material:

· Steel Expanded metal mesh. Standard carbon steel is prone to rust if it’s exposed to moisture or humid environments. To prevent rust, steel Expanded metal mesh is often coated with protective finishes, like galvanised or powder coatings, which create a barrier against corrosion. Galvanised Expanded metal mesh, in particular, has a zinc coating that provides long-term resistance to rust.

· Stainless steel Expanded metal mesh. Stainless steel is highly resistant to rust and corrosion due to its chromium content, which forms a protective oxide layer. It’s a good choice for applications exposed to harsh weather, marine environments, or chemicals. However, it can still corrode under extreme conditions, like saltwater exposure, without proper maintenance.

· Aluminium Expanded metal mesh. Aluminium does not rust because it doesn’t contain iron, but it can oxidise. Aluminium oxidation creates a protective layer that shields the metal underneath, which actually helps it resist further corrosion. This makes aluminium Expanded metal mesh suitable for outdoor applications.
