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, LWD, strand width, sheet thickness or gauge, sheet width, sheet length, raised or flattened type, and the required galvanizing route. These parameters affect weight, open area, 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 Galvanized Expanded Metal Mesh?
Galvanized expanded metal mesh is carbon steel sheet that is slit and stretched into a continuous diamond pattern, then protected by a zinc coating. It provides strength, ventilation, visibility and drainage while improving corrosion resistance for industrial, construction and outdoor applications.
YueChu Metal manufactures galvanized expanded metal mesh, galvanized expanded metal sheet, galvanized steel expanded metal, raised and flattened panels, screens and galvanized expanded metal grating for B2B buyers. For UK and European searches, the same product is commonly described as galvanised expanded metal mesh.
- Pre-galvanized steel or hot-dip galvanized after expansion.
- Raised and flattened mesh with custom SWD, LWD, strand width and gauge.
- Sheet, panel, screen and grating formats for project and wholesale supply.
- Metric and imperial specifications with export-ready packing.
Material & Application Notes
Pre-Galvanized vs. Hot-Dip Galvanized After Expansion
Pre-galvanized expanded metal is produced from zinc-coated sheet and is commonly selected for economical indoor or moderate-exposure applications. Hot-dip galvanized after expansion is coated after slitting and stretching, giving more complete zinc coverage over strands, bonds and cut edges. Confirm the exposure environment and coating requirement before ordering.
Raised vs. Flattened Galvanized Expanded Metal
Raised galvanized expanded metal retains the three-dimensional bonds for traction and rigidity. Flattened galvanized expanded metal is rolled for a smoother, thinner surface that is easier to frame, form and fabricate. Related product details are available on our raised expanded metal and flattened expanded metal pages.
Common Applications
Galvanized expanded metal mesh is used for safety walkways, industrial grating, machine guards, perimeter fencing, security screens, equipment enclosures, shelving, ventilation panels and outdoor construction components.
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.

Frequently Asked Questions
What is galvanized expanded metal mesh?
Galvanized expanded metal mesh is carbon steel sheet that is slit and stretched into a diamond pattern, then protected with a zinc coating. It combines strength, ventilation, drainage and corrosion resistance for outdoor and industrial applications.
What is the difference between pre-galvanized and hot-dip galvanized after expansion?
Pre-galvanized expanded metal is made from zinc-coated sheet before slitting and stretching. Hot-dip galvanized after expansion is zinc coated after the mesh is formed, providing more complete coverage of strands, bonds and cut edges. The preferred option depends on environment, budget and required service life.
Do you supply raised and flattened galvanized expanded metal?
Yes. We manufacture raised galvanized expanded metal for traction and rigidity, and flattened galvanized expanded metal for a smoother, thinner surface used in guards, screens, enclosures and architectural fabrication.
Can you manufacture custom galvanized expanded metal sizes?
Yes. Buyers can specify SWD, LWD, strand width, sheet thickness or gauge, sheet dimensions, raised or flattened type, zinc coating route, edge treatment, quantity and packing requirements.
What information is needed for a galvanized expanded metal quote?
Please send the required product type, base steel grade, sheet thickness or gauge, SWD, LWD, strand width, sheet size, galvanizing method, zinc coating requirement, quantity, application and destination port. Drawings or samples help us quote accurately.
Is galvanized expanded metal suitable for outdoor use?
Yes. Galvanized expanded metal is commonly selected for outdoor guards, fencing, walkways, screens and equipment protection. Final suitability depends on the exposure environment, coating specification, fabrication and maintenance requirements.
How is galvanized expanded metal packed for export?
Sheets and panels can be protected with waterproof material, steel or plastic strapping, pallets, wooden cases and custom labels. Packing is selected according to sheet size, surface protection, shipment method and destination requirements.
Do you supply galvanised expanded metal mesh for UK and European buyers?
Yes. Galvanised expanded metal mesh is the common UK spelling of galvanized expanded metal mesh. We support metric specifications, project drawings, export packing and documentation for European distributors, contractors and fabricators.
