Woven wire mesh is a flexible mesh made by interweaving wires in a woven pattern. Its unique construction allows it to be used in filtration, sieving, and architectural applications where flexibility and fine openings are required.

The production of welded wire mesh involves the following steps:

Selection of Wires

The journey of woven wire mesh manufacturing begins with the selection of right wire material. Stainless steel, epoxy coated, nickel, aluminium etc, are the common woven wire mesh material, serving the foundation. These materials must meet stringent standards to ensure the final product&#;s durability and strength.

Wire Drawing: Crafting the Foundation

Wire drawing is the initial step where the selected raw materials are drawn through a series of dies to reduce their diameter gradually. This process improves the wire&#;s tensile strength and prepares it for further transformation.

Wire Coating: Enhancing Durability

To enhance resistance to corrosion and rust, wires may be coated with protective layers in some situations. Common coatings include galvanization and PVC. These coatings not only extend the mesh&#;s lifespan but also make it suitable for various environments.

Weaving: The Art of Interlocking

Weaving is the heart of wire mesh production. Wires are interwoven to create the desired pattern. The woven mesh&#;s weave type, such as plain, twill, or dutch woven weaves, determines its properties and applications.

Finishing Touches

After weaving, the mesh undergoes finishing treatments, which may include washing, coating, or additional heat treatment. These steps enhance the mesh&#;s durability, appearance, and resistance to environmental factors. For instance, a protective coating can prevent rust and corrosion, extending the mesh&#;s operational life.

Expanded Wire Mesh Manufacturing Process

Wire Mesh Manufacturing Process: Understanding How Wire Mesh is Made

Expanded wire mesh is produced from a single sheet of metal that is slit and stretched to form a diamond or hexagonal pattern. This process results in a lightweight yet strong mesh with an open structure, making it ideal for applications requiring strength and ventilation.

The production of expanded metal mesh involves the following steps:

Material Selection

Typically made from aluminium, mild steel, or stainless steel, expanded metal mesh offers a range of properties suited to various uses. Steel provides high strength, aluminium offers lightness and corrosion resistance, while stainless steel combines both durability and aesthetics.

Sheet Preparation

The process begins with preparing a metal sheet, which is cleaned and cut to the desired dimensions. This sheet serves as the raw material for the mesh.

Expansion Process

In the expansion stage, the metal sheet is subjected to a process where it is slit and simultaneously stretched or expanded. This transforms the flat sheet into a mesh with a distinct pattern of openings.

Cutting and Flattening

After expansion, the mesh is cut to the required size and shape. It is then flattened to ensure uniformity and ease of handling, making it ready for various applications.

Selecting the right wire material and diameter is crucial for achieving the desired properties in the final product. Factors like flexibility, strength, and resistance to corrosion are considered.

Knitting Process

Wires are knitted together using specialized machines that interlock them in a pattern similar to textile knitting. This process imparts the mesh with its characteristic flexibility and elasticity.

Quality Assurance

The knitted wire mesh undergoes rigorous quality checks to ensure it meets the required specifications. This may include testing for strength, flexibility, and consistency in knitting patterns.

Crimped Wire Mesh Production

Wire Mesh Manufacturing Process: Understanding How Wire Mesh is Made

Crimped wire mesh production involves crimping wires before assembling them into a mesh. This crimping process adds strength and rigidity, making it suitable for heavy-duty applications in industries like mining and construction.

The crimped wire mesh manufacturing process involves:

Material Selection

Crimped wire mesh is commonly made from steel or stainless steel, which provides the necessary durability and resistance to wear and tear.

Crimping the Wires

Wires are fed through a crimping machine, which deforms them into a wavy pattern. This crimping adds structural strength and flexibility to the mesh.

Assembly of the Mesh

Crimped wires are then assembled into the desired mesh configuration, either by welding or weaving. This step ensures that the mesh has the required dimensions and structural integrity.

Surface Finishing

Finally, the crimped mesh undergoes surface treatment, which may include coating or galvanizing to enhance its resistance to environmental factors and extend its lifespan.

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 , SAE , and SAE 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 used 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 2 mm) automatically. The wire rods can be cut to any size ranging from 0.8 metre to 12 metre with a max tolerance of 2 mm.

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 used 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.
