Custom Copper Expanded Metal Sheets & Panels
Decorative, conductive and corrosion-resistant open metal for project supply
Copper expanded metal combines a continuous one-piece mesh structure with the distinctive color, conductivity and natural aging behavior of copper. It is specified for visible architectural work, decorative screens and selected technical applications.
We review alloy, temper, expansion direction, mesh geometry, surface condition, fabrication and packing together because soft copper surfaces require careful production and handling.
What Is Copper Expanded Metal?
Copper expanded metal is made by slitting and stretching copper sheet into a continuous diamond or other open pattern. It is also searched as copper expanded metal mesh, copper expanded metal sheet, expanded metal copper and copper expanded metal screen.
Unlike woven copper wire mesh, expanded copper retains connected strands and bonds from one sheet. The result provides open area, visual depth and material continuity without welded or woven intersections.
- Distinctive natural copper appearance for visible architectural applications.
- Continuous one-piece structure with no welded wire intersections.
- Useful electrical and thermal conductivity where the complete design is verified.
- Custom mesh openings, strand dimensions, thicknesses and sheet sizes.
Decorative Copper Expanded Metal
Copper mesh can be used for ceilings, wall panels, partitions, furniture, display fixtures, feature screens and architectural details where the warm metal color and natural aging process support the design concept.
Copper Expanded Metal Screens
Custom panels may be reviewed for ventilation, screening, equipment protection and selected shielding applications. Functional performance depends on opening size, thickness, conductivity, joints, grounding and installation.
Natural Copper Patina
Uncoated copper changes from bright copper to darker brown tones and may develop green patina over time. Exposure, humidity, salts, handling and cleaning all affect the final appearance.
How to Specify Copper Expanded Metal Mesh
For an accurate quotation, specify copper grade and temper, SWD, LWD, strand width, material thickness, profile, sheet dimensions and surface finish.
- Material: Copper grade, composition and temper.
- Profile: Raised or flattened expanded metal.
- Mesh geometry: SWD, LWD, strand width and required open area.
- Sheet size: Finished width, length and expansion direction.
- Edges: Trimmed, untrimmed, cut to size or framed.
- Finish: Natural, polished, brushed, aged, patinated or protected.

Copper Surface and Patina
Copper is sensitive to fingerprints, moisture, salts and handling. Natural color variation and oxidation should be expected unless the project specifies controlled finishing and protective treatment. Samples should be approved for visible architectural work.
Copper Expanded Metal Price
Pricing depends on the current copper material cost, grade, temper, thickness, mesh pattern, sheet size, finish, fabrication, quantity, inspection, packing and destination. Quotations may have a limited validity period because copper prices fluctuate.

- Define visible surfaces, edge condition and surface protection requirements.
- Provide performance criteria for shielding, conductivity or ventilation projects.
- State quantity, inspection, packing, destination and required quotation validity.
Copper Expanded Metal FAQ
What is copper expanded metal?
It is copper sheet slit and stretched into a continuous open mesh. The strands and bonds remain part of one sheet without woven or welded wire intersections.
How is copper expanded metal different from woven copper mesh?
Expanded copper is formed from one sheet, while woven copper mesh is produced from interlaced wires. The products differ in opening geometry, surface profile, stiffness, fabrication and appearance.
Does copper expanded metal change color?
Yes. Uncoated copper naturally darkens and may develop brown or green patina according to exposure, handling and environment. Specify a controlled finish if color consistency is required.
Can copper expanded metal be supplied flattened?
Raised and flattened profiles can be reviewed according to copper grade, temper, thickness, opening pattern, dimensions and order quantity.
Can copper expanded metal be used for EMI or RF shielding?
Copper conductivity may support shielding applications, but performance depends on the mesh opening, thickness, joints, grounding and complete enclosure design. Required test standards must be provided.
What information is needed for pricing?
Send the copper grade, temper, profile, thickness, SWD, LWD, strand width, sheet dimensions, finish, quantity, application and destination port.
How do you protect copper expanded metal during export?
Surface separation, protective wrapping, waterproof material, corner protection, pallets and wooden cases can be used to reduce scratches, deformation and moisture exposure.
