Stainless steel tension bars, also known as stainless tension rods, stainless steel tie bars and stainless tie rods, are manufactured in the UK by Petersen.
Stainless steel tension bar systems consist of a threaded stainless steel tie terminated with an SBS-450 fork clevis adjuster at each end. The stainless steel SBS-450 fork and clevis pins are designed in accordance with BS5950-1:2000, EN 1993-1-11:2006 and EN 1993-1-8:2005 and are machined, not cast, from a high strength duplex stainless steel.
The SBS-450 fork clevis ends allow a generous amount of adjustment and are normally supplied in pairs with one left hand and one right hand threaded end. After installation the 316 stainless tension bar can be rotated to set the correct length and locked into position using tapered lock cover nuts.
316 stainless steel tension bars are manufactured from specially drawn high tensile bar stock with rolled threads. Stainless tension bar systems are available in up to 6m single lengths and couplers can be used to span further.
