PC STRAND (UNBONDED)
PC STRAND (UNBONDED)
Unbonded Pc strand coated with anti-corrosion grease and high density polyethylene (HDPE) to Prevent the moisture from reaching the steel strands,Thus they can provide high corrosion resistance.
Unbonded Pc Strand is widely used in Bridges, Silos, high rise buildings, ground anchoring, Dams, precast
segment, etc. Produced as per standard ASTM ASTM A-416
