Prestressed concrete Wire and strands - Constructalia

1 WireSolutionsPrestressed concreteWire and strandsWe are now moving beyond what the world expects of , Move & Energize!QualityAll WireSolutions plants are certified ISO 9001. But quality cannot be reduced to a certificate alone: it is our constant attention, through choice of raw material, process control, regular inspection and continuous improvement. We test samples in accordance with local the origins of prestressing, in France in the 1950 s, ArcelorMittal and its subsidiaries have been commited to develop steel specifications and processes to produce the highest quality prestressing wire and strands . Innovation is part of our culture: it is no coincidence that we were the first in the world to develop individually protected stay-cable strands and very high tensile is commited to safety. This is true in our factories. This is also true for any construction site where our prestressing wire and strands are used: bridges, cryogenic storage, industrial, commercial and residential buildings where safety is critical.

2 Designing, producing and promoting prestressing products of an increasing quality has always been a daily preoccupation for each and everyone in the three factories dedicated to prestressing wire and strands , WireSolutions is certified in more than 20 countries and delivers to all five continents. More than 50 years experience gained with these products, an extensive knowledge of the market and the backing of ArcelorMittal, the largest steel producer worldwide, makes us one of the world leaders in the concrete uses much less materials than reinforced concrete : savings can reach 40% of the overall mass! Longer spans, thinner and lighter elements allow a reduction in number of piles, height of buildings, consumption of energy in freight and handling, therefore CO2 complete rangePlain, indented, for pipes 2 or 3 wires, plain or indented7 wires, plain or indentedUnbondedStay cablesWireStrandsCommon specificationsSpecifications after stress relievingFatigue behaviour,2 000 000 cycles for.

4 ArcelorMittal prestressing steel guarantees a very low relaxation. Deviated tension is current in post-tensioned structures, stay-cables and even some prefabrication methods. By strict adherence to manufacturing processes and routine destructive tests, WireSolutions products exceed standard requirements. Fatigue triggers quick, unexpected and costly rupture in structural steels. This is especially true with stay-cable strands , submitted to high levels of stress variation. Choice of steel quality, specific production processes and control allow ArcelorMittal steel to reach a high fatigue corrosion and hydrogen embrittlement are known to be a threat for high-tensile structural steels, especially in environments containing chlorides. For several decades, WireSolutions has been producing wire and strands satisfying the most stringent demands in the industry in this data7 wire strandsEN 10138 BS 58963 wire strandsEN 10138 Nominal diameterDiameter toleranceGradeNominal weightNominal steel areaMinimum breaking strengthYield strength minimum load at 1% extension inchmminchmmksiMPalb/1000 g/minch mm lbskNlbskN1 + + + + + + + + + + + + + + + + + + diametermmTensile strengthMPaMassg/mCross sectional area mm2 Tolerance on mass %Minimum breaking strength kNMaximum breaking strength kNYield strength at % elongation wire strandsASTM A 416/A 416 MNominal diametermmTensile strengthMPaMassg/mCross sectional area mm2 Tolerance on mass %Minimum breaking strength kNMaximum breaking strength kNYield
