12.7mm and 15.24mm prestressed cable strand is one of the most important products in our enterprise, which is used to match the high end structures of concrete such as railways, highways, bridges, mine, nuclear power plant, hydropower, large-span buildings and so on.
1. High tensile strength with good performance
2. 12.7mm PC strand1720/1860/1960MPA, 15.2mm PC strand 1570/1670/1770/1860/1960MPA, 15.7 mm PC strand 1860MPA.
3. We can produce the tensioning pc strand according to ASTMA416, AS1311, BS5896, JISG3536, GB/T5224-2003.
4. Unbonded and bonded low relaxation 7 wires prestressed cable.  

Prestressed Concrete Cable is mainly for the use of prestressed concrete structure reinforced. such as large –span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-story industrial buildings, stadiums, and coal mines, etc.

1. Unbonded and bonded prestressing steel strand has a good corrosion-resistance and less friction of un-bonded tendons and can be easily bended into curve shape.
2. It is suitable for making cast-in-place concrete of long-span and wide building cover, heavy load prefabricated beam and other special structures.
3. Prestressed concrete cable 12.7mm and 15.24mm PC strand has a lot of characters such as no need of grout hole and grouting, convenient to use, material-saved, bending easily and so on.  
4. High tensile strength and elongation; low relaxation value; small stress losing; excellent durable anti-fatigue performance.
