How is expanded metal made?
Expanded metal Sheet is produced from metal sheet or roll through stamping and expanding, which forms a wide array of diamond shaped openings with uniform sizes.
Compared with the traditional flat metal sheet, expanded metal mesh has more notable advantages for its versatile applications.
Owing to the expanding process, the metal sheetcan be expanded up to 8 times its original width, losing up to 75 % its weight per meter, and becomes harder.So it is lighter, less expensive than a single metal sheet.

What is expanded metal?
Expanded metal mesh types includes raised expanded steel mesh (also called standard or regular expanded metal) and flat expanded metal mesh.
Raised expanded metal mesh has diamond openings with slightly raised surface. Flattened expanded metal mesh is manufactured by passing the standard expanded sheet through a cold roll reducing mill, forming diamond openings with flat surface.
The form of the meshes is normally rhombic but more shapes are available, such as hexagonal, oblong and rounded. The size of the meshes varies from very small meshes 6 x 3 mm suitable for filters, to very large meshes 200 x 75 mm often used for architectural applications.
The materials most often utilised for expanded metal are mild steel, aluminium and stainless steel, but we also offer in other materials (brass, copper, titanium, zinc, etc).
The length and width of the sheet and the grid parameters are always described according to the following pictures.
