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.
