DURAROPE Climbing and Mountaineering Ropes
Request QuoteDescription
All mountaineering and rappelling ropes are made of a polypropylene core with a nylon sheath, or 100% nylon. Nylon offers the closest combination of strength, resiliency, elasticity, and abrasion resistance that is ideal for mountaineering use.
Ropes used for climbing are normally dynamic. These are designed to stretch upon loading, absorbing shock and dissipating the energy generated when arresting a fall. Dynamic ropes are of nylon, and where required the core is shrunk and stabilized by steam to increase the elongation under load and to reduce changes after becoming wet.
Major Benefits
- High performance, well balanced properties
- Excellent abrasion resistance
- Kink free, no twist – can be easily coiled by left or right handed person
- Pliable – easy to handle and store
- Excellent knot retention
- Torque-free rope construction gives a non-rotating rope
- Stronger, more abrasion resistant and longer lasting than cotton, jute, manila or sisal ropes
Durarope climbing ropes are of a kernmantle construction consisting of a core (kern) covered by a sheath (mantle). The core is the main load-bearing element and largely determines a rope’s characteristics, such as strength, static elongation, and maximum impact force. The sheath is braided tightly around the core and its primary purpose is to protect the core against abrasion. The relationship between the core and sheath also contribute to rope handling characteristics. Sizes range from 8 to 11 mm diameter.
