• Strongest of all ropes in the low rotation and rotation resistant product range - confirmed by Bridon’s “Powercheck” testing of a sample from each production length.

• Greatest resistance to rotation of all ropes in the Rotation Resistant product range - confirmed by Bridon's unique "Twistcheck" type testing program.

• Superior bending fatigue life when compared with conventional Rotation Resistant ropes - confirmed by laboratory testing and extensive field experience.

• Excellent resistance to crushing and abrasion resulting from the overall compactness and robustness of the rope and the Dyform strands - recommended when multi-layer spooling is involved.

• Reduced elongation results from increased steel content and the Dyform process.


• Optional plastic coating of IWRC to further extend fatigue life, improve structural stability and resistance to corrosion.
