Products - Concrete Reinforcing Welded Mesh

With more than 50 years experience in the production of reinforcing mesh, BRC Mesh is a leading supplier of customised reinforcing products to most industry sectors. Reinforcing mesh has a wide variety of uses, ranging from the ordinary household to heavy industry.

In many construction applications such as reinforcing, a welded mesh fabric is preferred to rebar, particularly if Ferro-Fabrik is used. Ferro-Fabrik is a top quality product  conforming to SANS 1024:2006. It has greater features and strengths than rebar (minimum 485Mpa) allowing a material saving of ±8%, and allows for time saving when fixing on site.

Features of reinforcing mesh

  • The unique deformed wire pattern (curry pattern) offers superior bonding, improved stress distribution and crack-width control.
  • Ferro-Fabrik is available in a wide range of diameters and apertures. The product 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.
  • Specifications allow for cold rolled wire with a minimum ultimate tensile strength of 510Mpa and a high resistance to fatigue.
  • Also available on request: hot dipped (galvanised) mesh.

Quality Control

Reinforcing mesh is produced to SANS 1024:2006 quality standard and complies to ISO 9001:2000. 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) - up to Ref. 245, and sheets (6m x 2,4m) manufactured according to standard sizes. Wire diameter varies 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 13mm and 150mm.

Customised mesh is available on request according to specifications provided. Customers and design engineers should contact BRC Mesh before embarking on the design of such mesh.

  • The MRM 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.
