Confirm availability for your complete specification.The ranges above do not establish availability for every material, profile or size. We review the complete specification and confirm manufacturability before production. Use inches or millimeters consistently. SWD / LWD are pitches, not clear openings; specify SWO / LWO separately. A 1220 × 2440 mm commercial sheet is not the exact equivalent of 4 × 8 ft.

View all 11 mesh patternsWhat Is Expanded Metal?
Expanded metal is a metal mesh made by slitting and stretching a solid sheet into a continuous pattern of openings, most commonly diamond-shaped. The strands stay connected at integral bonds, forming a single-piece, open metal structure.
Unlike woven wire mesh, it has no interlaced wires; unlike welded mesh, it needs no welded intersections to form the pattern. Material, strand dimensions, opening geometry, overall thickness and surface treatment determine its suitability for guards, screens, fencing and architectural panels.
Raised vs. Flattened Expanded Metal
Compare the two profiles before deciding on the final specification.
| Feature | Raised Expanded Metal | Flattened Expanded Metal |
|---|---|---|
| Surface | Raised strands and angled bonds | Rolled to a flatter, smoother surface |
| Rigidity | Three-dimensional profile adds stiffness | Profile changes during flattening; confirm load requirements |
| Appearance | Textured, directional diamond pattern | Low-profile, uniform diamond pattern |
| Common uses | Guards, fencing; suitable heavy mesh for verified flooring loads | Screens, infill panels, cladding and ceilings |
| Fabrication | Allow for overall raised mesh thickness | Smooth profile for framing and finishing |

View applicationWhy Choose Expanded Metal?
Practical benefits for industrial fabrication and architectural design.
- One-piece construction
- Continuous strands and integral bonds are formed from a single sheet, without woven or welded mesh intersections.
- Efficient material use
- Slitting and stretching creates openings without punching out slugs of metal from each opening.
- Airflow & visibility
- The open pattern allows air, light and visibility through the panel, depending on strand geometry and opening size.
- Versatile configurations
- Combine the material, profile, diamond pattern, sheet dimensions and finish around your application.
- Fabrication flexibility
- Suitable mesh can be cut, formed and incorporated into frames or fabricated components.
- Strength & rigidity
- The connected structure provides rigidity. Load capacity depends on material, geometry, orientation and supports.
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 Expanded Metal Manufacturing Process
From technical review to export shipment.
Step 01Inquiry & Technical Review
Send your drawing or sample, material, panel size and quantity. We review the mesh pattern, diamond direction and any cutting or forming requirements.
Step 02Specification Confirmation
Agree on SWD / LWD pitches, strand width, base thickness, finish and tolerances. A reference sample can be reviewed when needed before production.
Step 03Manufacturing & Processing
Sheet is slit and stretched to form the agreed mesh pattern. Flattening, cutting and further fabrication follow the confirmed order requirements.
Step 04Quality Inspection
Check mesh dimensions, strand dimensions, panel size and appearance against the agreed specification. Confirm the inspection points and records required for your order.
Step 05Packing & Shipment
Prepare sheet bundles with the agreed surface protection and identification. Confirm packing, handling and shipment arrangements for the destination.
- Drawing-based manufacture
- Send the drawing revision, material grade, SWD / LWD, strand dimensions and profile. We review the combination and agree on dimensions and inspection requirements before production.
- Custom sheet sizes & cutting
- Define finished width and length, diamond direction, open or closed edges and tolerances. Mark cutting, bend lines and frame interfaces on the drawing so fabrication can be reviewed together.
- Coatings & surface finish
- Specify mill finish, galvanizing or powder coating to suit the material and exposure. Confirm whether coating is before or after fabrication, including treatment of cut edges.
- Export packaging
- Confirm bundle or pallet arrangement, surface protection, panel identification and unloading requirements. Include the destination and any packing instructions with your inquiry.

Expanded Metal FAQ
What is expanded metal used for?
Expanded metal is used for machine guards, fencing, ventilation screens, equipment enclosures, architectural facades, ceilings and selected access flooring. Match the material, opening dimensions and surface profile to the application; flooring also requires verified loads and supports.
What is the difference between raised and flattened expanded metal?
Raised mesh retains the angled strands produced during expansion. Flattened mesh is passed through rolls to reduce the profile and produce a smoother surface. Select the profile around the load, handling, fabrication and appearance required.
Can expanded metal be galvanized or powder coated?
Yes. Discuss the base material, intended environment and coating requirements when ordering. Specify whether galvanizing is required before or after fabrication, and provide a color reference for powder coating.
Should I start with a mesh pattern or a sheet size?
Start with mesh geometry when airflow, screening or a required clear opening drives the design. Start with the sheet dimensions when replacing a panel or fitting an existing frame. The final order needs both the mesh specification and finished panel dimensions.
What materials are available for expanded metal?
Options include carbon steel, galvanized steel, stainless steel, aluminum, copper and titanium. Availability of a particular pattern, thickness and finished size depends on the material grade and production requirements.
Can you make custom sizes and specifications?
Send a drawing or reference sample with opening dimensions, strand width, metal thickness, overall size, profile, finish and quantity. We will review manufacturability and confirm the final specification before production.
Is expanded metal suitable for walkways and platforms?
Raised grating can be used for access flooring where drainage and traction are needed. The panel thickness, diamond direction, framing and support spacing must be checked against the project load requirements before use.
Is expanded metal stronger than welded wire mesh?
Not necessarily. Expanded metal has continuous strands and integral bonds; welded wire mesh has wires joined at intersections. Relative strength depends on material grade, strand or wire dimensions, mesh geometry, loading direction and support conditions.
Is expanded metal suitable for outdoor applications?
Yes, when the material and finish suit the exposure conditions. Aluminum, an appropriate stainless steel grade, or suitably galvanized or coated carbon steel may be considered. Confirm the environment, coating specification and cut-edge protection before ordering.
What should I send for an expanded metal quotation?
Include the material grade, raised or flattened profile, SWD and LWD, strand width, thickness, sheet or panel dimensions, quantity, finish, application and shipping destination. Attach drawings or reference photos when available.
