Galvanized PC Wire and Strand Produce Process

Galvanized PC wire

1. Wire rod
   Raw material for steel wire products is supplied by steel mill. Steel mills make wire rod by hot rolling process from billet.
2. Surface treatment
   Descaling wire rod removes rust and scales on the surface of wire. Surface coating wire rod facilitates drawing.
3. Drawing
   Descaled and surface coated wire rod is brought to 1st drawing machine to draw to required diameter and to give mechanical properties suitable for application.
4. Galvanizing
   Zinc coating process for corrosion resistance.
5. Stabilizing
   Heat treatment process using high frequency relieves and removes stress.
