Expand Metal
Expand Metal
Expanded metal is a metal mesh formed by spreading a metal plate while making a staggered cut by a blade, and shaping the cut into diamond (Standard type) or hexagonal pattern (Grating type). Various materials are used, including iron, aluminum, stainless steel, nickel, and titanium. Expanded metal is lightweight and has excellent post-processability. In addition, there are no mesh joints, and the applied load is dispersed. As a result, the tensile strength is strong. Taking advantage of this feature, expanded metal is used in a wide range of applications, including air vent windows in electrical equipment, acoustic equipment, firing trays for sintering process, machine covers, cable racks, fences, construction, and civil engineering materials.
Name of Each Part
| SW (Short Way of Diamond) | Center-to-center distance in the short dimension of the mesh |
|---|---|
| LW (Long Way of Diamond) | Center-to-center distance in the long dimension of the mesh |
| T (Thickness) | Plate thickness |
| W (Width) | Step Width (Feed Width） |
| Strand | Narrow portion of the mesh |
| Bond | Wide portion where the mesh intersects |
Specifications of Expanded Metal
◆Standard type (JIS G3351)
Standard type have diamond-shaped meshes, and the bond part is short. It has an orderly mesh, strong impact resistance, and is used in a wide range of applications. In addition, it is often used for interior and exterior, etc. because of its beautiful appearance.
Material: Carbon steel
◆Grating type (JIS G3351)
Grating type have hexagonal pattern meshes, and its bond part is long. It is more robust compared to other types because of the standard on which people are assumed to ride. It has a high anti-slip effect and is often used in walkways and building materials. Material: Carbon steel
Material: Carbon steel
◆Small mesh type of expanded metal
Small mesh type of expanded metal is thin, light and easy to process. Used in applications such as EMI shielding, ornaments, aircrafts, vehicles, electric appliances, chemical equipment, mechanical equipment, filters, etc.
Shearing for Expanded Metal (Bond Shearing and Random Shearing)
◆ Bond shearing
Shearing at the bond section to match the mesh
◆ Random Shearing
Shearing at strand section
Mesh direction of the Expanded Metal
◆ Short-Long type
The long side of diamond (LW) runs parallel to the shorter dimension of the expanded metal sheet
◆ Long-Long type
The Long side of diamond (LW) runs parallel to the long dimension of the expanded metal sheet
Flat processing of expanded metals
Expanded metal features raised surfaces, but this may be a disadvantage for some applications. In order to cope with this problem, roller machining is possible so that entire mesh is flat.
