Today, let's take a look at the differences between the static rope and the low Stretch kernmantle rope produced by our company, so that everyone can better find the rope that suits their needs.

 I. Static Rope

First, let me introduce a relatively common 10.5 mm static rope. We can see that its sheath has a 48-strand braid with three black tracer threads. The core consists of 13 strands, independently braided into a spiral core.

Special core treatment and post-processing techniques give the static rope low elongation and better control. Its performance indicators comply with the European standard EN 1891 and it has passed both the EU CE certification and the UIAA (International Mountaineering and Climbing Federation) certification. The static rope is designed for professionals in vertical fields and is widely used in high-altitude work, rope access, rescue, tree climbing, canyoning, etc.

Here are the detailed parameters for the 10.5 mm static rope:

A cost-effective Type A rope. Complies with EN 1891, Type (A), Diameter (10.5mm), Static Strength (30.3kN), Number of Falls (15), Impact Force (5.2kN), Static Elongation (3.4%), Sheath Slippage (0.4%), Weight per Meter (74g), Sheath Percentage (36.4%), Core Percentage (63.6%), Material (Nylon). Certified with International CE (0082) and UIAA, along with a domestic third-party commissioned inspection report.

II. Low Stretch Kernmantle Rope

Next, let's introduce the Jiaolong Kernmantle Rope. Firstly, its sheath uses a braiding method with a lower number of carriers, such as 32 carriers. This lower carrier count braiding method allows our sheath to have better abrasion resistance. The core uses three independently braided core strands to provide better stability and fullness. The material is a polyester sheath paired with a nylon core.

Core of the Low Stretch Kernmantle Rope

The triangular parallel arrangement braiding technology effectively disperses external forces applied to the kernmantle rope, providing breaking strength far exceeding the average destructive force. The high-quality polyester fiber sheath braiding effectively enhances the rope's resistance to oil and chemical corrosion, making it more suitable for various harsh environments. It is matched with equipment complying with the EN 341:2011 standard, providing safer escape efficiency.

Jiaolong Low Stretch Kernmantle Rope uses 32-carrier sheath braiding technology combined with a three-strand core. The special three-strand core structure and meticulous production process control effectively disperse applied external forces, providing breaking strength far exceeding the average destructive force. It maintains a compact structure when combined with various types of hardware equipment, offering more stable control.

The high-quality polyester fiber sheath braiding effectively increases the rope's resistance to oil and chemical corrosion, making it more suitable for various harsh environments.

1. Jiaolong Low Stretch Kernmantle Rope is suitable for use with equipment conforming to EN 341:2011.

2. Perfect integration with equipment provides higher braking force.

3. Specially softened for improved comfort during use.

4. Oil and chemical corrosion resistant.

5. Special three-strand core structure.

Available diameters: 9.6 mm, 10.5 mm, 11 mm,12mm,13mm.

Jiaolong Low Stretch Kernmantle Rope has a sheath/core slippage rate close to 0%. This mechanical-type static rope is designed for use with equipment such as descent devices and powered ascenders; it is particularly suitable for providing long-distance descent or hauling operations when used with machinery. Features high breaking strength, high abrasion resistance, and good grip.

Here are the detailed parameters for the 9.6 mm model:

Complies with EN 1891, Type (A), Diameter (9.7mm), Static Strength (27kN), Figure-Eight Knot Strength (16.1kN), Static Elongation (3.5%), Sheath Slippage (0%), Weight per Meter (69g), Sheath Percentage (39.3%), Core Percentage (60.7%), Material: Polyester Sheath, Nylon Core, Suitable for equipment conforming to EN 341:2011, CE certified (0082).
