How to Choose Expanded Metal Mesh

Expanded metal is made by punching and stretching a solid sheet so that it opens into diamond-shaped holes, with no weaving or welding needed. The strands stay joined to each other, so the sheet is strong and stays in one piece.

Start with the job. For machine guards, window guards, speaker grilles and partitions, a thin strand with a small opening is usually enough. For platforms, walkways and step mesh, choose a thicker strand, because it carries more load. For concrete reinforcement and fencing, the strand and opening are chosen to suit the structure.

Then choose the material: mild steel for general work, galvanized iron where rust is a concern, stainless steel 304 or 316 for wet or hygienic places, and aluminium when you need light weight.

Our sheets have openings from 0.5 mm to 50 mm and come in any sheet size and thickness. The standard specifications table above lists strand and opening sizes with weight per square metre, and other specifications can be made on request. Send us the material, strand thickness, opening size, sheet size and quantity for a quote. You may also like our perforated sheets and welded mesh.
