What is Expanded Metal?
Expanded metal is produced by simultaneously slitting and stretching a solid sheet of metal. This creates a one-piece mesh with diamond-shaped openings, where every strand is connected without any welds or joints. The process uses nearly 100% of the raw material, making it extremely material-efficient.
The mesh retains its three-dimensional, raised diamond pattern after expansion. Provides excellent grip and drainage. Used for walkways, platforms, and stair treads.
After expansion, the mesh is cold-rolled flat to create a smooth surface. Used for machine guards, ceiling panels, filtration, and decorative applications.
Since expanded metal is made from a single sheet with no welds or joints, it is inherently stronger than fabricated alternatives. Every strand is integral to the original sheet.

Frequently Asked Question
Trusted in more than 100 countries and 4 million customers.
Standard (raised) expanded metal retains its 3D diamond shape after expansion, providing excellent grip and drainage. Flattened expanded metal is cold-rolled after expansion to create a smooth, flat surface suitable for guards, screens, and decorative use.
For a given weight, expanded metal provides superior strength because it is made from a single sheet with no joints. Each strand is part of the original sheet. Welded mesh relies on the strength of individual weld points, which can be a failure point under stress.
Yes. Flattened expanded metal in SS304 or Aluminium is widely used for building facades, sun screens, and decorative wall cladding. It provides ventilation, light diffusion, and a distinctive visual pattern.
We supply from a single sheet for urgent requirements up to bulk tonnage for project orders. Standard sizes are typically available from stock.
Yes. MS HR expanded metal is commonly painted or powder-coated for outdoor use. SS304 and Aluminium are typically supplied in mill finish.
