Strength (Relative strength)
The basic property of the rope is its strength, which is determined by the material used. The strength is measured under rope tension at breaking point. The unit of measurement is the Newton. If the rope is braided, its strength is reduced by 10%. Knotting the rope reduces its strength by 50% (in the case of steel rope it is up to 90%). Other factors affecting this property include UV radiation, exposure to chemicals and heat. Therefore, always store ropes in a safe place .
Melting point (Melting temperature)
Heat can affect the functionality of ropes made of synthetic materials. The surface of the rope may begin to "glaze". The rope then loses its strength. It is therefore not advisable to store ropes in the vicinity of a heat source.
Maximum long-term-use temperature
Indicates the maximum long-term exposure to heat. At this temperature, the rope will not be damaged, but its technical parameters may be reduced.
With ropes it is important to distinguish between the breaking load and the working load. The working load indicates the maximum rope tension that is still safe.
UV radiation resistance
Textile ropes can lose their strength due to UV radiation. If you are using the rope in conditions where it will be exposed to high UV radiation, choose ropes made of polypropylene. Polypropylene ropes resist UV very well. Despite this property of the fibre itself, we add even more protection to the ropes in the form of a surface treatment.
Indicates the rope’s resistance to abrasion and sharp edges.
