Note - As agreed between the manufacturer and the customer for steel from steel grades 25, 30, 35, 40, allowed reduction of tensile strength of 20 N/mm, compared with the standards set out in the table, while improving the rules elongation of 2% (abs ).
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.
