GAW welded steel mesh is made with steel wire spot welded into form of panels or rolls, then thorough galvanized or hot dipped in "melt zinc pool".

GAW weld meshes are stronger compared with GBW and suitable for long-time service as fencing panels (light mesh) or construction mesh (heavy mesh).

Processing steps applied for GAW Galvanzed After Weld Wire Mesh Manufacturing as following.

Fencing Panels

Wire Rod
Stainless steel wire, iron wire and galvanized wire drawn from wire rod are mostly used raw materials for production of GAW wire mesh. The raw material used for product material is of low carbon steel from various steel manufacturers, commonly known as wire rods. The raw material grades are SAE 1008, SAE 1010, and SAE 1012 which has a percentage of carbon in the range of 0.08 to 0.12.

Cold Rolling
Most wire for welding is cold rolled wire. Cold rolling is a metal working process in which metal is deformed by passing it through rollers at a temperature below Recrystallisation temperature. Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metals crystal structure. These defects prevent further slip and can reduce the grain size of the metal.

Straightening & Cutting of Wire and Wire Rods
Specialized machinery imported from Italy and other countries is utilised for straightening and cutting process. The cold rolled wire rods in the coil form is passed through pre set die and cartridge units (special sets for different diameter wire rods) present in the straightening and cutting machine, where the wire rods are first straightened and then cut to set length (precision up to 2mm) automatically. The wire or wire rods can be cut to any size ranging from 0.8 Metre to 12 Metre with a max tolerance of 2mm.

Spot Welding
The welding processing applied for GAW and GBW is spot welding. Welded wire steel fabric is manufactured with automatic welding machines, where wires are welded together in square or rectangular grids. The wires are welded by electric resistance in an automated state of the art machine which controls welding parameters precisely. All the settings for dimensions and welding are programmable. The weld is formed by a controlled combination of pressure, intensity and duration of electric current to develop fusion of the wires. Welded steel mesh fabric utilizes welded intersections for bond and anchorage.

Bending & Cutting
The galvanized after welded steel mesh fabric can be supplied in bent form for fencing or other structure uses. Cut into panels or sheets. Two separate machines are available for cutting and bending operation. The cutting machine is utilised for cutting the finished meshes to desired dimension. It is a motorised unit, capable of cutting meshes at a speed of 2 to 3 cut per second. The bending machine available is used to bend the cut meshes to the required shape (as required by design). The machine is capable of bending sheet to any angle (Up to 180o). Depending upon the design requirements, the sheets requiring cutting and bending will be taken for this operation else the meshes will be directly taken for despatch from the third process.

Galvanizing Finished Mesh
After the Bending and Cutting process comes the final stage in manufacturing process, galvanizing or hot dipping. The whole mesh sheet is put into a "pool" of melt zinc liquid and get thorough protection of galvanizing. The welded steel wire mesh becomes corrosion resistant after galvanizing processing.
