Expanded metal sheets are created by slitting and cold-forming metal as it expands in a press. This process creates diamond-shaped openings that are nominally measured the long way of the diamond (LWD) and the short way of the diamond (SWD). Raised, or standard, expanded sheets offer a skid-resistant surface and a high strength-to-weight ratio. Flat expanded sheets have been rolled for a smooth, level surface. Expanded metal sheets are measured by the percentage of open area, which is the ratio of open space to total space in a given area. A sheet with a larger percentage of open area contains less material than one with a smaller percentage.

Application of Expanded Metal Sheet
Expanded Metal is used widely throughout the transportation industry, agriculture, security, machine guards, floorings, construction, architecture and interior design. The use of this kind of expanded metal mesh is highly beneficial, and of cost saving and low maintenance.
We manufacture a full range of standard and flattened expanded metal, structural grating, micro mesh and decorative patterns. Raw material can be produced in carbon, galvanized, stainless steel or high strength alloy steel. Certain alloys of copper, brass, bronze and plastics can be expanded as well.
