Instruction for unwinding reinforcing strands (ropes)
Coils of reinforcing strands (ropes) are marked with a paper self-adhesive label with the image “arrow” to indicate the direction of unwinding of the strand in the following order (Figure 1):
– On the reinforcing strands (ropes) of the right twist, the arrow is directed inside the coil;
– On reinforcing strands (ropes) of the left twist, the arrow points outward of the coil.
Figure 1 Direction of unwinding of a strand (rope)
To avoid tangling of strands (ropes) during their processing, it is necessary to unwind a reinforcing strand (rope) depending on the direction of stranding (rope) in the direction indicated by the arrow (Figure 1).

| Note a. The elastic modulus (E) can be taken as 195 GPa (kN / mm2).Note b. The nominal linear density (mass of one meter of length) of the product is calculated from the cross-sectional area and density of 7.81 kg / dm3. Note c. The characteristic value of 0.1% of the maximum allowable load is calculated for all diameters as 88% of the specified characteristic value of the maximum load. Relaxation after 1000 hours no more than 2.5% Special properties in accordance with the additional requirements of FprEN 10138-3: 2009. | ||||||||
