Expanded Metal Mesh

Expanded Metal Mesh


Expanded metal mesh, also known as expanded metal, is made through a pressured slitting and stretching process to create diamond-shaped openings in metal sheets. The mesh design results in open areas that allow for air, light and water ventilation, while still acting as a barrier to larger objects. Expanded metal mesh is produced in a standard (raised) diamond pattern or a flattened variety, usually made of aluminium, carbon steel, galvanized steel or stainless steel. In some cases, expanded metal mesh is considered an alternative to sheet metal or wire mesh. It combines some of the best features of both materials by providing a material that is stronger than thin wire mesh and has better air flow and drainage than sheet metal. Expanded metal mesh is an excellent option for custom wire baskets that require more tensile strength than wires can provide. In addition, expanded metal cuts down on the need for extra welding operations, compared to using individual steel wires, thus making it faster and easier to make sturdy baskets.


Uses of expanded metal mesh include architectural, walkway platforms, grates, drainage covers, construction, automobiles, electric instruments, fencing, vessels, roads, machinery and mesh covers.


One of the common grades of low carbon steel expanded metal mesh is JIS G3131. JIS G3131 is a low carbon steel that when galvanised, effectively holds up against corrosion and provides exceptional strength, coupled with formability. Hot-dipped galvanised JIS G3131 expanded metals are a cost effective solution for long term to medium corrosion protection. Galvanised JIS G3131 expanded metal mesh offer excellent durability and can be powder coated to improve the appearance for architectural applications.

Galvanised expanded metal mesh are commonly hot-dip galvanised in accordance to ASTM A123 or EN ISO 1461 standard.
