Unbonded PC Strand Produce Process
- Wire rod
Raw material for steel wire products is supplied by steel mill. Steel mills make wire rod by hot rolling process from billet.
- Surface treatment
Descaling wire rod removes rust and scales on the surface of wire. Surface coating wire rod facilitates drawing.
- 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.
- Stranding
Positioning the wires within the strands.
- Stabilizing
Heat treatment process using high frequency relieves and removes stress.
- HDPE Coating
Filling grease or wax and coating HDPE into PC wire.
