Application

They are used as prestressed reinforcement of prestressed reinforced concrete structures.
Stabilized reinforcing strands have a number of advantages over those manufactured using tempered technology: an increase in the yield strength and tensile strength by 10-15%; increase in elastic limit by 25-30%; reduction of stress losses during relaxation by 5-8%; increasing the reliability and durability of the structure.
It is possible to manufacture ropes both of round wires and of wires with a periodic profile.

Unwinding of coils is carried out from the inside. In-line winding allows you to unwind the coil without tangling and crossing the coils of the reinforcing strands, and the ability to produce measured winding eliminates the presence of any waste during processing.

(12.7) — this standard size of the prestressing strand is made with a compression. Reinforcing strands with compression have increased structural density, high breaking force.
