Welded Wire Mesh Manufacturing Process, include galvanize welded wire mesh and vinyl coated welded wire mesh production processing.

Wire Rod
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. Stainless steel wire, iron wire, galvanized wire is the ideal raw materials.

Cold Rolling
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
Specialized machinery from Italy is utilised for straightening and cutting process. The cold rolled wire rods in the coil form is passed through preset 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 rods can be cut to any size ranging from 0.8 Metre to 12 Metre with a max tolerance of 2mm.

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 fabric utilizes welded intersections for bond and anchorage.

Bending & Cutting
Two separate machines from Schnell, Italy 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.

Finished Mesh
After the Bending and Cutting process comes the final stage in manufacturing process, galvanizing or PVC coating.
