Low Relaxation PC Strand

The advantage of unbonded pc strand

In the construction, playing unbonded prestressed concrete strand outside grease and sheathing, strand and concrete isolation, feel free to loose, kept and concrete bond status, it said inviscid Results prestressing strand.

Galvanized unbonded prestressed steel strand for reinforcement works, galvanized steel coated with grease and plastic sheath, double guarantee its preservative effect. With China's rapid economic development, the bonded prestressed steel strand and more extensive use, but mainly for static load large civil engineering, large-span factory or high-rise buildings.

The unbonded prestressing strand advantages: construction speed, reduce the thickness of the beam and slab, increase the structural performance and economic effects (that is to do with the general structure of the ten-story high-rise, prestressing strand can cover a 11-story) . Especially in public Span Building beams, columns. Can greatly reduce the deflection of the beam. Use the unbonded prestressed process, eliminating the trouble of filling. In addition, bridge construction and large-span the garage prestressed construction due to the dynamic load (vehicle driving the vibration damage to the flat-slab), the design is the need for the unbonded is ordinary steel strand, due to the construction grouting direct and concrete bonding, resulting in a stronger bond strength is not like bonded prestressed strand construction as anchoring both ends of the difficult, can enhance the safety factor.
