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 accurate quotation and production, expanded metal mesh should be measured by SWD (Short Way of Diamond), LWD (Long Way of Diamond), strand width, sheet thickness, sheet width, and sheet length. These expanded metal mesh specifications directly affect opening size, weight, strength, ventilation rate, and application performance.
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 Flattened Expanded Metal?
Flattened expanded metal is raised expanded metal that has been cold rolled to create a smoother, flatter, and more level surface. The rolling process reduces the overall thickness while retaining the continuous one-piece mesh structure.
It is often selected where easier fabrication, improved appearance, a smoother contact surface, or more consistent panel thickness is required for guards, shelves, screens, panels, and fabricated components.
- Smoother surface for handling and secondary fabrication.
- More uniform thickness and flatter appearance than raised mesh.
- Available in multiple metals, opening patterns, and finishes.
- Suitable for guards, shelves, screens, panels, and partitions.
Benefits of Flattened Expanded Metal
Flattened expanded metal offers a smoother surface, easier cutting and forming, improved appearance, uniform panel thickness, and practical installation for guards, shelves, screens, fabricated parts, and visible panel work.
Applications of Flattened Expanded Metal
Common applications include flattened expanded metal for machine guards, flattened expanded metal panels for shelves and partition infill, smooth surface expanded metal for decorative screens, and fabricated sheets for filters, ceiling details, and architectural cladding projects.
Flattened vs. Raised Expanded Metal
Raised expanded metal keeps a three-dimensional profile for rigidity and traction, while flattened expanded metal is cold rolled to create a smoother surface and lower profile. Buyers usually choose flattened expanded metal sheet products when fabrication, handling, finishing quality, or visible panel appearance matters more than added traction.
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.
