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.

Features of Expanded Metal Mesh
Anti-corrosion and anti-rust.
Various colours can be selected as needed.
Excellent artistic effect for decoration.
Good tensile strength and durability.
Application of Expanded Metal Sheet
Expanded metal mesh has a wide range of uses, graceful shapes , strong processing capability. A major advantage of expanded is that the mesh is formed from a single piece of material and the process is not wasteful and therefore cost effective.
Main use: metal surface treatment and after processing, are widely used in large venues, both inside and outside decorative, aerospace, petroleum, chemical industry, metallurgy, medicine, paper making, filtration, breeding, packing, mechanical facilities, protection, handicraft manufacturing, high-grade speaker grille, children’s seat, baskets, basket, highway protection, and heavy machinery, boilers, oil mines, locomotives, tonner steamship, work platform, staircase, walkway. Also can be used for construction, highway and bridge as reinforced use.
