DYWIDAG Prestressing Threaded bar systems
DYWIDAG Prestressing Steel Threadbars, 15mm - 75mmØ are suitable for all static loading applications. Additionally, for
post-tensioning and dynamic applications, DYWIDAG Prestressing Steel Threadbars 26.5mm - 40mmØ, offer a fatigue resistance in excess of 2 million load cycles over a tensile range of 630 - 682N/mm2 as specified in the European Technical Approval No. ETA - 05/0123 and ETAG 013. Stress relaxation when loaded to 70% fpu is less than 3.5% over a 1000 hour period in accordance with BS4486.
