The "+" means that the mechanical properties and hardness defined for storing data, and test results indicate that in the quality.
In coils with single banding by steel strap 0,8-1,0х32 mm or by wire rod 8.0 mm in 4 places min. equally distributed over coil. Outer diameter of a coil –1300 mm max., inner diameter – 820 mm min.
Option 1 – coil weight 1400-1800 kg.
Option 2 – coil weight 1800-2500 kg.
