Unbonded PC Strand Wire

Unbonded prestressed steel strand is mainly used in post-tensioning prestressed system. The difference between unbonded prestressed steel strand and bonded steel strand is that the prestress does not bond with the surrounding concrete, because there is grease and sheath outside. During its work, the steel strand is allowed to slide longitudinally relative to the surrounding concrete, and the preload is transmitted to the concrete by the anchorage. Unbonded steel strands are used for cast-in-place floors of large-span and large bay buildings, prefabricated beams with large loads and other special structures. It has the characteristics of no need to reserve holes, grouting, simple construction, material saving, random bending, etc.

Application:	PC Strands are mainly used in prestressed concrete structure reinforcement, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-storey industrial buildings, stadiums, coal mines, etc.

Features:

1）High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, firm connection with concrete, low stress, stable construction, good combination with steel reinforced concrete; saving material, reducing distortion and construction weight, increasing the abrasion resistance, water resistance, stiffness.
2）We offer PC Strand which confirm to the technical standards such as GB/T 5223, GB/T 5224, ASTM A-416, BS 5896, JIS G3536 or the standards agreed by both of the customers and us.
3）PC strand can also be supplied in various forms for pre- or post-tensioning applications, with plain or galvanized material ranging from 3 wires, 7 wires, 19 wire and compacted construction.

Application:

1）Our PC strand is mainly used for the reinforcement of prestressed concrete structures, such as large-span railway and road bridges, major bridges, silos, buildings, dams, floor slabs, foundations, large concrete vessels, atomic reactor buildings, stadiums, airport hangers, pre-cast segments, crane beams, anchorages and multi-storey industrial buildings etc.

2）Our PC strand is also used for the construction of highways, poles and water towers in civil construction, and energy source sea transportation, house buildings, water control projects, and rock and earth anchoring components to increase the tensile force.
