Static Rope

Static rope: A rope essential for rock climbing, used with descenders or ascenders, with high strength, wear resistance, and anti-aging properties.

Static ropes are usually between 9 mm and 11 mm in diameter, so they are usually suitable for ascending, descending, and using pulleys. Thinner ropes are the choice for climbing high mountains, where the main consideration is weight. Static ropes must have a primary color coverage rate of 80%, and the entire rope cannot have more than two secondary colors.

Static ropes are traditionally used in caving and rescue but are often used in high-altitude rappelling. Static ropes are designed to have as little elasticity as possible. In applications such as fixed ropes, its drag load will be on a huge wall, cliff, or cave. Therefore, it is worth using more wear-resistant ropes with minimal expansion. Static ropes have a very small contraction and will stretch by about 2% under the action of body weight. To protect the ropes from a lot of extra wear, they are usually made thicker and equipped with wear-resistant protective sheaths. The inner core is made of multiple thinner twisted-pair fibers, so it can reduce the impact of huge pressure.
