Expanded Metal mesh is traditionally seen as a metal material with diamond shaped holes. Expanded Metal is produced by an expanding machine, which uses a pressured slitting and stretching process to transform solid metal sheets and coils into expanded mesh. The process, known as expanding metal, was pioneered by Hope. Although modern machines are computer programmed and speedier than the original machines the process of expanding has remained largely unchanged.

Variety: small, medium and heavy expanded metal mesh. Expanded aluminum mesh, expanded platinum filtration mesh, expanded brass mesh, expanded copper mesh, expanded stainless steel mesh, expanded nickel mesh. Opening in the shape of diamond, hexagonal or special shape.

Use: Used with concrete in buildings and construction, maintenance of equipments, making of arts and crafts, covering screen for first class sound case. Also fencing for super highway, studio, highway. Heavy expanded metal can be used as step mesh of oil tanks, working platform, corridor and walking road for heavy model equipment, boiler, petroleum and mine well, automobile vehicles, big ships. Also serve as reinforcing bar in construction, railway and bridges.

Expanded metal is one continuous single sheet of mesh produced when a flat metal plate is sheared and stretched but is left intact at the 'knuckles'. It is available in a variety of thicknesses with differing sizes and designs of the apertures.

The strands and knuckles are set at a uniform angle to the plane of the sheet. This adds strength and rigidity and distributes the load to the supporting frames. Because there are no welds or joins it operates as a structural member that distributes loads evenly over a wide area.

The high strength to weight ratio makes it suitable for many industrial and ornamental applications. No loose strands or welds means minimal deterioration from constant exposure or movement.

A further feature is the provision of an excellent anti-slip surface. This makes the product suitable for ramps (e.g. inclined walkways adjacent to conveyors) platforms and stair treads.

The open nature of the product provides good visibility through the mesh as well as the easy passage of air and sound whilst ensuring security and protection.
