Perforated, Expanded & Grating
Expanded Metal Mesh in Thicknesses From 0.5 mm to 8 mm
One sheet slit and stretched into mesh - no wire, no welds, nothing to unravel.
Product Overview
What Expanded Metal Mesh Is and Who Buys It
Expanded metal mesh is made by slitting and stretching a single sheet, so the mesh has no welds and no loose wire ends.
It is made from expanded steel mesh, aluminium, stainless steel, nickel and other metals, and used as steel reinforcement in petroleum, chemical industry and building decoration.
It is also used for fencing on roads, railways, civil buildings and water conservancy works, and for protecting machines, electrical equipment, windows and aquatic breeding.
Key Benefits
- Eighteen published specifications with thickness, short way and long way dimensions, strand width and weight.
- Thickness from 0.5 mm foil-weight mesh to 8 mm structural mesh.
- Multiple base metals - steel, aluminium, stainless, nickel.
- Widths to 2 m and lengths to 4 m on the heavier specifications.
Who It Is For
Buyers Who Specify Expanded Metal Mesh
- Petroleum and chemical plant fabricators using it as reinforcement
- Architectural and interior contractors
- Machine and electrical equipment guards
- Road, rail and water conservancy contractors
- Aquaculture equipment builders
Problems It Solves
Welded or woven mesh can unravel at a cut edge. Expanded mesh is one piece of metal, so it cannot.
Reinforcement mesh needs mass, not aperture. The weight column - 0.73 to 28.26 kg per square metre - is the number that actually matters, and it is published here.
Thin mesh bought for a heavy guard deforms on first impact; thicknesses run to 8 mm for exactly that case.
Punched sheet wastes the slug. Expanding wastes nothing, which shows up in the price of heavy gauges.

Materials
Material Options
Steel is the standard. Aluminium is chosen where weight is the constraint, stainless where corrosion is, and nickel for specialised chemical service. Because the mesh is formed from a single sheet, the base metal's own corrosion behaviour carries through with no coating at the cut edges to worry about.
Quality Control
Check thickness, short way and long way dimensions and weight per square metre against the specification line you ordered. Weight is the fastest single check that the right specification has been shipped.
Certifications
- ISO9001 quality management
- Import and export licence
Customization Options
- Any of the eighteen published specifications
- Steel, aluminium, stainless steel or nickel
- Raised or flattened mesh
- Sheet sizes to order within the published width and length ranges
- Framed panels for guarding
Manufacturing Process
How Expanded Metal Mesh Is Made
Sheet selection
Flat sheet selected in the ordered thickness from 0.5 mm to 8 mm.
Slitting and stretching
The sheet is slit and stretched in one operation to form the diamond pattern.
Flattening
Where a flat sheet is ordered, the raised mesh is rolled flat.
Cutting
Sheets cut to the ordered width and length.
Finishing
Edges trimmed and sheets stacked for shipment.
Comparison
How It Compares
| Product | Where It Fits |
|---|---|
| Expanded metal mesh | One-piece; no welds; up to 8 mm thick; strongest per kilogram |
| Perforated metal | Punched; exact round holes; thinner gauges; higher cost per square metre in heavy sheet |
| Welded wire mesh | Welded wires; lighter; cheaper for fencing and animal housing |
Use Guide
- Select by weight per square metre when the mesh is structural or a reinforcement layer.
- Select by short way and long way dimension when it is a guard or a screen.
- Orient the long way of mesh across the span for maximum stiffness.
- Use flattened mesh where anything will slide across the surface.
- For petroleum and chemical reinforcement duty, confirm the base metal with your enquiry.
