Specify raised or flattened mesh, sheet thickness or gauge, SWD, LWD, strand width, sheet dimensions, finish, quantity and destination for a factory quotation and export packing plan.
Drawings, samples and standard size references are welcome. Our team can review the opening pattern, sheet size, tolerance, finish and packing requirements before production.
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 SWD (Short Way of Diamond), LWD (Long Way of Diamond), strand width, sheet thickness or gauge, sheet width and sheet length. These values affect open area, weight, rigidity, fabrication and price.
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 Carbon Steel Expanded Metal?
Carbon steel expanded metal, also called mild steel expanded metal, is made by slitting and stretching a solid steel sheet into a continuous diamond opening pattern. Because the strands and bonds remain part of one sheet, the material has no welded wire joints and provides a practical balance of strength, airflow, visibility, drainage and weight.
It is commonly ordered as raised carbon steel expanded metal for traction and rigidity, or as flattened carbon steel expanded metal for a smoother and thinner surface. Sheets can be supplied in mill finish or with a protective coating selected for the operating environment.
- Economical steel mesh for high-volume industrial fabrication.
- Continuous one-piece construction without welded intersections.
- Custom openings, strand dimensions, thicknesses and sheet sizes.
- Suitable for cutting, framing, bending and fabricated assemblies.
Carbon Steel Expanded Metal Applications
Typical applications include machine guards, walkway and platform surfaces, stair treads, fencing, security screens, ventilation guards, equipment enclosures, storage racks, partitions, trailer components and OEM fabricated parts.
Raised vs. Flattened Steel Expanded Metal
Raised mesh is preferred where traction, drainage and rigidity matter. Flattened mesh provides a smoother profile for guards, shelves, infill panels, screens and components that require easier handling or a more even surface.
Custom and 4x8 Steel Expanded Metal Sheets
Buyers can request standard or custom sheet dimensions, including 4x8-style requirements. Production feasibility depends on the opening pattern, thickness, material utilization, tolerance, quantity and shipping plan.
Material & Application Notes
Surface Finish Selection
Untreated carbon steel requires appropriate storage and corrosion management. For humid, outdoor or visible applications, buyers can specify oil protection, paint, powder coating or galvanizing according to the required service environment and appearance.
Information Required for Pricing
Carbon steel expanded metal price depends on steel grade, thickness, opening pattern, strand width, sheet size, finish, quantity, tolerance, fabrication and packing. Send a drawing or complete specification rather than relying on a product name alone.
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.

Buyer questions
Carbon Steel Expanded Metal FAQ
What is carbon steel expanded metal?
It is a carbon or mild steel sheet that is slit and stretched into a continuous diamond mesh. The one-piece structure provides open area, airflow and useful strength without welded wire intersections.
Is mild steel expanded metal the same as carbon steel expanded metal?
The terms are often used for similar low-carbon steel expanded metal products. The exact steel grade should still be confirmed when strength, chemistry, welding or compliance requirements matter.
What is the difference between raised and flattened carbon steel expanded metal?
Raised mesh keeps its three-dimensional bonds for traction and rigidity. Flattened mesh is leveled after expansion to provide a smoother, thinner surface for guards, screens, shelves and fabricated panels.
Can you supply 4x8 carbon steel expanded metal sheets?
We can review standard and custom sheet dimensions, including 4x8-style requirements. Please confirm the opening pattern, thickness, strand width, profile, quantity and finish.
Which finish should I choose for steel expanded metal?
Mill finish or oil protection may suit indoor fabrication and controlled storage. Paint, powder coating or galvanizing may be more suitable where corrosion resistance, color or outdoor service is required.
What information is needed for pricing?
Send the raised or flattened profile, steel grade if specified, thickness or gauge, SWD, LWD, strand width, sheet dimensions, finish, quantity, application and destination port.
How do you pack carbon steel expanded metal for export?
Packing options include waterproof protection, film, strapping, pallets, wooden cases and custom labels. The plan is selected according to sheet size, surface protection, shipment method and destination.
