Wire mesh as reinforcement reduces the project costs and speed up the construction period as opposed to rebar since:
Wires mesh is supplied in a ready to place condition and thus time and manpower for steel, bending and tying are saved.
Wire mesh is easier and faster to place resulting in reduction of time and cost by 50-80%.
Cutting at site is not needed thus no material loss has to be calculated.
The yield strength of wire mesh is higher, therefore, the weight of reinforcing steel is reduced in the range of 40%.
Weldmesh is manufactured from bright drawn mild steel wire, electronically welded at every intersection. It is produced in self-color (flash copper coating), galvanized after manufacture and PVC coated. Certain specifications are also produced from wire, both lightly and heavily galvanized, before welding.
The wire from which the mesh is made is manufactured to ASTM A 853-93 specifications for mild steel wire for general engineering purposes. Mesh may also be produced from this wire heavily galvanized in accordance with ASTM A 641-92 Class 3 specification for zinc coatings on steel wire, or the wire mesh may be galvanized after manufacture.
All mesh consists of wires running the length of the roll or panel known as the line wires, to which cross wires are welded at right angles.
British standard prefered meshes in stock size steel 4.8m long x 2.4m wide.
