Tension rods are available in carbon steel, which can be supplied hot dip galvanized, or stainless steel (AISI 316 and Duplex). The yield strengths available are 460 and 520 N/mm², higher strength up to 800 N/mm² can be supplied to special order.

 

As standard tension rods are delivered with fork(or spade) fittings, lock covers and pins at each end. Tension bars are available in lengths of up to 11.8 m. Length is from pin hole to pin hole.

 

Adjustments within each fork end is as follows: M10 to M56: + / - ½ diameter. M64 to M100: + /-25 mm.

Turnbuckles adds further adjustment as follows: M10 till M24: + /-25mm. M30 to M100: + /-50mm.

Special turnbuckles, with a bigger adjustment, are available on request.

 

Tension rods are available in diameter 10 to 100 mm. Stainless tension rods in diameter 10 to 76 mm.

Stainless cables are available in diameter fra 3 to 26 mm.
