ULTRA 24-12 ropes are constructed using specially twisted yarns of NIKA-Steel® fibers with High Tenacity Polyester fibers (in a 50% – 50% w/w combination respectively) in the outer layers of the strand. Each strand is composed of mixed NIKA-Steel® / HT Polyester yarns in the outer layers and NIKA-Steel® yarns in the core layer.
Their mechanically balanced structure, accordant to EN ISO 10556 specification, protects the strands’ outer layers against abrasion while achieving extra high breaking strengths.
ULTRA 24-12 ropes’ layout is ideal for demanding applications where high abrasion resistance & extra high strength are required. They have very good resistance to sunlight & chemicals, very good resistance to cyclic loading, and their efficiency remains the same both in wet and dry conditions.
ULTRA 24-12 ropes are produced according to international standards such as EN ISO 10556. They are user-friendly, rotation-resistant, and easy to splice. They comply with the latest regulations and recommendations of OCIMF for the safe mooring of tankers.
