Custom Color Coated Expanded Metal Sheets & Panels
RAL color finishes for architectural, industrial and OEM projects
YueChu Metal supplies custom powder coated expanded metal mesh, sheets and fabricated panels for distributors, contractors, architects, fabricators and OEM buyers in the United States, Europe and Australia.
Specify the base metal, raised or flattened profile, mesh opening, sheet or panel size, RAL color, gloss, coating environment, quantity and destination for a production review and export quotation.
We review the complete system—not color alone—including base metal, pretreatment, mesh geometry, fabrication, edge condition, coating specification and packing protection.
Expanded Metal Specifications & Dimensions
Compare reference patterns used in the USA, UK, Germany, France and Australia. Confirm material, finished dimensions and availability for your order.
For an accurate quotation, specify the mesh before the finish: SWD, LWD, strand width, material thickness, profile and sheet or panel dimensions. Then add the coating requirements.

Pitch ≠ clear opening. Diagram labels: TL = short way, TB = long way, b = strand width, d = metal thickness, B = sheet width and L = sheet length. Specify whether the short and long dimensions on your drawing are bond-center pitches (SWD / LWD) or clear openings (SWO / LWO).
- LWD × SWD
- Long × short way of the diamond pitch, measured between corresponding bond centers.
- Strand width & thickness
- Strand width is w; base metal thickness is t. Raised overall thickness T is a separate dimension.
- SWO / LWO
- The short and long dimensions of the clear opening between strands; these are smaller than the corresponding diamond pitches.
- Open area & sheet size
- Open area is the percentage occupied by openings. Sheet size is the overall width and length; specify diamond orientation separately.

All dimensions are in mm. LWD and SWD are the long and short diamond pitches, measured between corresponding bond centers. ≈ indicates an approximate value. Scroll horizontally to compare all fields.

What Is Powder Coated Expanded Metal?
Powder coated expanded metal is raised or flattened expanded metal finished with an electrostatically applied dry powder and cured to form a continuous protective color layer. It is also searched as coated expanded metal, color coated expanded metal, black expanded metal mesh or painted expanded metal mesh.
The finish is widely specified where buyers need both the functional open area of expanded metal and a controlled architectural or industrial appearance. Coating performance depends on the complete specification, especially base metal, pretreatment, powder chemistry, film build, curing and service environment.
- Uniform color coverage for visible mesh, sheets and fabricated panels.
- Custom RAL colors and gloss levels for coordinated project finishes.
- Open structure supports ventilation, daylight, drainage and visibility.
- Suitable for cutting, framing and project-specific panel fabrication.
Architectural Expanded Metal
Powder coated aluminum or steel expanded metal is used for facades, rainscreens, ceilings, wall panels, partitions, balustrade infill, sunshades and decorative screens where color consistency and mesh geometry are part of the design.
Industrial Coated Expanded Metal
Black or custom color coated expanded metal can be supplied for machine guards, equipment enclosures, storage fixtures, security panels, fencing and OEM components that require a clean, identifiable finish.
Custom RAL Color Mesh
Provide the required RAL reference, gloss level, indoor or outdoor exposure, sample approval process and visible surface expectations. Color approval should be completed before bulk production.
Specification & ordering
Color & Coating Approval
Confirm whether cutting, framing, bending or welding will be completed before coating.
- Define which surfaces and edges are visually critical.
- Provide the exact RAL color, gloss and texture requirement.
- State indoor, outdoor, coastal or industrial exposure conditions.
Expanded Metal Manufacturing & Customization
A slit-and-stretched sheet, configured around your project.
Slitting and stretching turn solid sheet into connected mesh. Raised mesh retains angled strands; rolling creates a smoother, flattened profile. Cutting, forming and finishing follow your agreed specification.
Custom options to discuss
- Material and grade
- SWD / LWD and clear openings
- Strand width and thickness
- Raised or flattened profile
- Sheet size and diamond direction

Buyer questions
Powder Coated Expanded Metal FAQ
What is powder coated expanded metal?
It is expanded metal sheet or mesh finished with electrostatically applied dry powder and cured to form a continuous colored layer. The finish provides a controlled appearance and helps protect the metal surface.
Which expanded metal materials can be powder coated?
Carbon steel, galvanized steel, stainless steel and aluminum can be reviewed. Pretreatment and coating selection must match the base metal and service environment.
Can you supply black expanded metal mesh and custom RAL colors?
Yes. Black, white, grey and custom RAL references can be reviewed. Please provide the exact color code, gloss level, texture and sample approval requirements.
Is powder coated expanded metal suitable for outdoor projects?
It can be suitable when the base metal, pretreatment, powder chemistry, film build and edge protection are specified for the exposure. Coastal and aggressive industrial environments need additional review.
Should panels be fabricated before or after powder coating?
Cutting, welding, framing and bending are generally reviewed before coating so the finished surfaces receive continuous treatment. The sequence depends on the panel design, tolerances and installation method.
What information is required for pricing?
Send the base metal, raised or flattened profile, thickness, SWD, LWD, strand width, sheet or panel size, RAL color, gloss, coating requirement, quantity, application and destination.
How do you protect coated panels during export?
Options include surface separation, suitable protective film, waterproof wrapping, corner protection, strapping, pallets, wooden cases and custom labels according to panel dimensions and finish sensitivity.
