Indented PC Strand with Strong Bonding Force
Indented PC strand, also called indented PC steel strand, is twisted by several indented PC wires. The indented PC wire has a strong nature of bonding force, therefore the indented PC strand can further strengthen the bonding force with concrete. What’s more, it has a broad applications in many fields, such as PC constructions, PC hollow slabs and high-speed railway sleepers.

Indented PC strand with indented surface treatment can strengthen the boding force with concrete.

Indented PC strand with high bonding force can widely used in PC constructions, PC hollow slabs, nuclear power projects, etc.
