The Wire
Galvanizing
Process
A continuous wire galvanizing plant transforms drawn Mild Steel (MS) wire into corrosion-resistant galvanized iron (GI) wire through a rigorous, sequential surface treatment and coating process.
Wire Drawing
The Process
Raw MS wire rod pulled through tungsten carbide dies, reducing diameter to target gauge while hardening the wire.
The Purpose
Drawing achieves the precise diameter and surface finish required. Each die reduces the wire gauge progressively to meet exact specifications.
Surface Cleaning
The Process
Wire surface mechanically descaled and cleaned to remove oxides, loose scale, and contaminants before chemical treatment.
The Purpose
Mechanical descaling ensures the wire surface is clean and uniform, preparing it for effective chemical pickling and zinc adhesion.
Pickling
The Process
Acid bath (dilute HCl) strips all rust, mill scale, and metallic oxides. Zinc cannot bond to oxidized steel.
The Purpose
This is a critical chemical cleaning step. The acid strips away all rust, mill scale, and metallic oxides from the surface of the MS wire.
Fluxing
The Process
Zinc Ammonium Chloride flux solution prevents re-oxidation and catalyzes the metallurgical bonding of molten zinc.
The Purpose
Fluxing prevents the bare steel from re-oxidizing before it hits the zinc bath, and acts as a catalyst to promote the metallurgical bonding of molten zinc to the steel.
Hot Dip Galvanizing
The Process
Wire passes through molten zinc bath at 450–460°C. Metallurgical reaction forms bonded zinc-iron alloy layers for lasting protection.
The Purpose
A metallurgical reaction occurs as the wire travels through the molten zinc, forming a series of tightly bonded zinc-iron alloy layers topped by a layer of pure zinc.
Cooling
The Process
Freshly galvanized wire is rapidly cooled and quenched to solidify the zinc coating and stabilize the surface.
The Purpose
Rapid cooling solidifies the zinc coating, locking in the metallurgical bond and ensuring uniform coating thickness across the wire.
Testing
The Process
Diameter, tensile strength, zinc coating weight, and dip test verified per batch before any product leaves the facility.
The Purpose
Every batch undergoes comprehensive QC testing — dimensional accuracy, tensile strength, coating weight, and surface quality — before dispatch clearance.
Packing
The Process
Finished wire wound into precise coils of 25–150 kg, wrapped in Hessian cloth and wire-bound for safe transport.
The Purpose
Proper packing protects the zinc coating during transit and ensures the wire arrives at the customer site in perfect condition.
Dispatch
The Process
Batch-tagged coils dispatched with Material Test Certificate via trusted freight partners across India.
The Purpose
Each dispatched coil comes with its batch test certificate, providing customers with full traceability and quality assurance documentation.
