Macalloy are proud to announce their Stainless 1030 post tensioning bar has successfully passed a fatigue test for a prestigious UK project at a UKAS accredited lab in Germany.
The fully threaded Ø32mm bar achieved 2 million cycles without failure at a Stress Range of 80MPa and a 65% Maximum Load. The testing requirements were in accordance with ETAG013, which corresponds to our ETA for the Carbon 1030 Post Tensioning System.
Prior to and following the fatigue test, a static load test was conducted, and the findings showed that the fatigue test had no negative impacts on the bar.
