Copper Expanded Metal
Copper expanded metal is a type of metal made from copper that has been cut and stretched into mesh form. It is commonly used for air and water filtration, sieving, and soundproofing applications. It has high thermal conductivity and excellent corrosion resistance, making it a popular choice for industrial and architectural applications.
We are constantly developing smaller and more patterns for numerous industry demands for more precise requirements. That is the reason why our SWD could be up to 0.2mm.
- Lightweight
- Low cost
- Exceptionally long life

Copper Expanded Metal
We have developed an extensive range of products and offer precision expanded metal in brass, phosphor bronze, and copper in various sizes, widths, and meshes. Copper expanded metal is used for industrial applications in the filter,(petrol)chemical, aeronautics, automotive and electrochemical fields. Their superior strength and versatile size lead to improved performance at a minimal cost.
Copper expanded metal has many advantages such as being lightweight, corrosion resistant, chemical resistant, and strong. It is also aesthetically pleasing due to its attractive look, making it a great choice for many applications. Copper expanded metal is also a great choice for electrical grounding, shielding, and other uses. Its open construction allows for maximum air flow and its electroplated finish helps to prevent oxidation.
Copper Expanded Metal Advantages
- Outstanding mechanical strength (Anti-ravel and Flexible)
- Micro expanded metal is a cost-effective alternative to perforated metal – especially when using high-value raw materials
- Can be manufactured according to the end user’s exact requirements
- Precision expanded metal mesh product for specialist industry needs
- It can be used in many fields, including engineering and manufacturing

Expanded Metal Terminology
1.1.1 bond, n-the solid intersection of two strands.
1.1.2 camber, n-the bow of a side or edge from end to end from a straight line.
1.1.3 diamonds, n-open area of metal after expanding.
Most expanded metal open areas or patterns are uniform diamond-shaped but may also be hexagonal, louvred, asymmetric, square, or other shapes, or combinations thereof.
1.1.4 edge configuration, n-refers to the edge condition of a sheet. May they be closed diamonds (bonded) or open diamonds (random) produced by shearing.
1.1.5 expanded metal, n-a rigid sheet of metal that is simultaneously slit and stretched, creating an open diamond pattern.
1.1.6 flattened, v (F)-expanded metal that has been cold rolled after expansion.
1.1.7 flattening, adv-the process of producing flattened expanded metal.
1.1.8 grating, n-expanded metal that is produced from heavier sheets.
1.1.9 levelness, n-(flatness of sheet), sheets shall be free from waves or buckets more than 1–1/2 in. from a plane surface.
1.1.10 LWD, n-nominal dimension, Long Way of the Diamond.
1.1.11 LWO, n-Long Way of the Opening.
1.1.12 regular-raised-standard, n-(R) expanded metal as it comes from the press. The strands and bonds are set at a uniform angle to the plane of the sheet.
1.1.13 SWD, n-nominal dimension, Short Way of the Diamond.
1.1.14 SWO, n-Short Way of the Opening.
1.1.15 shearing, n-cutting the sheet to a specific size or tolerance.
1.1.16 squareness, n-the dimensional variance a side and edge are out of square.
1.1.17 strand thickness, n-thickness of the base metal.
1.1.18 strand thickness, n, and strand width, n-can be varied to create different expanded metal products for other applications.
1.1.19 strand width, n-amount of material fed through top and bottom dies to produce one strand.
1.1.20 taper, n-edges of a sheet that deviates from parallel

- Piece Size: width (SWD) x length (LWD)
- Shearing: bond or random. Please check the below photo for reference
- Finish: PVC coating, PVDF coating, Pt coating, special, if any
Item No.: typically, expanded metal is specified like the following examples:
3/4 #16 S 3′ SWD x 6′ LWD Copper
- – 1/2inch= Short Way Of Diamond Dimension
- – #18 = Gauge (Usually not AWG, BWG, SWG, should be Washburn & Moen)
- – “S” = Standard (“F” would indicate flattened)
- – 3′ SWD x 6′ LWD = size of sheet width x length
- – Copper = material
