Powder Coating Expanded Metal Wire Mesh With Hexagonal Hole

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.

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.

• Materials: carbon steel, low carbon steel, iron, aluminum, stainless steel, copper, titanium
• Expanded metal thickness: 0.3mm-20mm
• Expanded metal panels siezes: 1/2,3/4,1'× 2',1' × 4',2' × 2',2' ×4',4' × 4',4' × 8',5' × 10',or made to size.
• Surface treatment: hot-dip galvanizing, anti-rust paint, powder coated, PVC coated, etc.

Advantage of expanded metal :

The advantages of using expanded metal are numerous and depend on the specific application. Below we have listed a few of the reasons for selecting expanded metal.

Light and cost efficient

It is a great advantage that expanded metal is not assembled nor welded, but always made in one piece.

• No metal is lost in the expanding process, hence expanded metal is a cost effective alternative to other products.
• Because there are no strained joints or welds, expanded metal is stronger and is ideal for forming, pressing and cutting.
• Due to the expansion the weight per metre is less than that of the original sheet.
• Due to the expansion a much bigger open area is possible compared to other similar products.

Agricultural and Industrial sectors

Examples of applications in the agricultural and industrial sectors where the use of expanded metal will be beneficial:

• Filtration
• Ventilation
• Laminated metal for draining floors for farm buildings
• Floors in containers
• Heat exchangers for several applications to hold the tubes
• Earthing of electricity
• Walkways for cranes
• Protection / shielding in front of dangerous elements
