Product Description Product Description 1x7 prestressed steel strand, low relaxation pre-stressed steel strand is composed by 7 wires, it has the features of high tensile strength and very low relaxation, which make it could replace traditional deformed steel bar well, and save a lot of steel material. Meanwhile ,it make long span concrete construction be possible.PRODUCT SPECIFICATIONSPECIFICATIONS PC STRAND GB/T5224-2014, FOR 1X7 PRESTRESSED CONCRETE STEEL STRANDStructureNominal diameterTolerance on DiameterNominal Area of SectionWeight of strandTensile Strength, RmMinimum Breaking load,Fm0,2% proof force , Fp0.2Elongation Lo=500mm, AgtCurvative of strandLay LengthThe Relaxation at 1000h (initial load to 70% of nominal max load ) (r/%) Not more than (mm)(mm)(mm2)(kg/1000m)(N/mm2)KNKN(%)mmmm 1X79.5+0.30-0.1554.8430186010289.83.5Max bow height = 25mm/ 1meter(12-16)d2.59.554.8430196010794.211. 1074.2582186013812111. 1074.2582196014512812. 70+0.40-0.1598.7775186018416212. 7098.7775196019317015.21401101186026022915.21401101196027424115. 701501178186027924617. 8019115001860355311 PC Strand ASTM A416/A416M:2012, 1X7 PRESTRESSED CONCRETE STEEL STRAND GradeNominal diameterTolerance on DiameterNominal Area of SectionWeight of strandTensile StrengthMinimum Breaking loadMinimum load at 1% ExtensionElongation Lo=610mmLay LengthThe Relaxation at 1000h (initial load to 70% of nominal max load ) (r/%) Not more than (mm)(in.)(mm)(mm2)(in.2)(kg/ 1000m)(lb/ 1000ft)(N/mm2)(KN)(KN)(%)mm 270(1860)9.533/8+0.65,-0.1554.80.0854322901860102.392.13.5(12-16)d2.511.117/16+0.65,-0.1574.20.1155823901860137.9124.112.71/2+0.65,-0.1598.70.1537755201860183.7165.315.243/5+0.65,-0.151400.21711027401860260.7234.617.787/10+0.65,-0.15189.70.294148710001860353.2318 PC STRAND pr EN10138-3:2011, 1X7 PRESTRESSED CONCRETE STEEL STRAND Steel NameSteel NumberDiameterTensile strengthCross-sectional areaMass per meterPermitted deviation on mass per meterCharacteristic value of maximum forceMaximum value of maximum forceCharacteristic value of 0.1% proof forceMin.Elong.
