Features of reinforcing mesh
The unique deformed wire pattern (curry pattern) offers superior bonding, improved stress distribution and crack-width control
Ferro-Fabric is available in a wide range of diameters and apertures. The products can be bent to shape as required
Manufactured from hard drawn wire (smooth) and cold rolled wire (deformed)
All intersections are resistant-welded thereby not reducing the tensile strength of the wires
Mesh has an average shear strength equal to 80% of the wire strength
The wire used has physical properties which are rigidly controlled to produce mesh with maximum weld strength combined with ductility
The steel specifications allow for cold rolled wire with a minimum ultimate tensile strength of 510Mpa and a high resistance to fatigue
Mesh is available in black (pre-galvanised) and galvanised sheets or rolls
Also available on request: plastic coated and hot dipped (galvanised) mesh
Quality Control
Reinforcing mesh is produced to highest quality standards and complies to ISO 9002. Thorough testing of wire strength, welds and aperture sizes is continuously performed at all stages of the manufacturing process. Final inspections ensure that highest standards are maintained.
Standard Sizes
Reinforcing mesh is available in rolls (60m x 2,4m) and sheets (6m x 2,4m), manufactured according to standard sizes. Wire diameters vary from 3,55mm to 12mm. Mesh aperture can be as small as 100mm x 100mm.
Special Mesh
Specialised machinery is used to produce weldmesh with non-standard aperture sizes. The spacing of wires in either direction is variable between 25mm and 150mm. Customised mesh is available on request according to specifications provided.

The MR Reference Number is the nominal mass in kilograms per square meter multiplied by 100.
The sizes given above are standard and are the most generally used. We can, however, manufacture mesh to other specifications,
both in size of wires and spacing.
Hard drawn wire to British standards 4482 has a minimum breaking strength of 510MPa and a minimum yield point of 485MPa.
