•Technicists in DAXIONG according to the demand of the market, promote products endlessly and develop various kinds of Helical Rib (Spiral) PC Strand. Successful accept patent certificate.
•Helical Rib PC strand appearance of the main characteristics are rolling pull-out process will deal with semi-finished products after the plastic deformation after the last drawing, so that wire formed on the surface of four consecutive convex-shaped rib, whether appearance or material processing method is excellent features to plain steel wire and strand.
•2007 DAXIONG research and developed 1*3H-9.0mm strand with TESS Japan, which is used in Beijing Metro Line 4. All performances in the test are excellent.
•Main technical descriptions:
•1)Good fixed performance. The reasonable shape form a continuous bump between steel wire and concrete, so as to achieve the perfect effect of fix.
•2)Steel wire cross-sectional area without any loss.Although steel wire by pull out and formed the bump on appearance, but the cross-section unchanged, without any loss.
•3)Reduced the length of transmission Significantly.For its special appearance characteristics,helical rib pc strand prestress transfer length is not more than 42D, especially suitable for pre-tensioned concrete structures and pre-tensioned prestressed concrete. This product increase the occlusal area between steel wire and concrete to advoid pre-stressed concrete structures stria longitudinal fissure and improve the bearing capacity and rigidity of component.
•4)Relaxation lower. Relaxation of prestressed steel wire spiral ribbed value has remained at 70% stress state under the stress of the loss of its 1.2 to 1.8% / KH between, which is lower than any country standards in the world for prestressed wire relaxation index.
•5)The anti-fatigue performance in many test indicate that helical rib PC wire have better ductility and toughness than plain steel wire and indented steel wire, extensions and cold bending index is still in the normal range of standard.
