Expanded Metal Sheets


Expanded Metal Sheets are produced in the following way – the row of mesh is cut into a roll or sheet and then the material is expanded. This procedure is repeated until the product gets its final shape.

Producing expanded metal sheets in this way gives a slightly crimped surface as the material, whilst being drawn, turns slightly vertically, that is why subsequently it is possible to press expanded metal in order to get an even surface.

Applications include
  • Decorative and Safety Covers.
  • Architectural Elements.
  • Bulkhead, Fillers, Grids and Reinforcers.
  • Staircases.
  • Grates.
  • Acoustical Insulation.
