LRPC Strand Lines

Rigid Stranding Machine


LRPC Strand is used as a reinforcement product for concrete beams and precast concrete structures. It is a high carbon wire product that is composed by 7 wires that are twisted or stranded together and then stretched in hot state in order to obtain the low relaxation property.

These lines are available in three different spool sizes and with different capacity:
The machine lines differ by the possibility of loading a spool size of 900, 1120 or 1250 flange diameter. The heat treatment of the strand is performed by an induction furnace that relieves the residual stresses as well as stretches the strand and comes in capacity of upto 1000 kW in power. Total Electrical power of the machine line is in excess of 3000 kW
The strand is rewound on a special lay by lay spooler in order to obtain a perfectly wound package
