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 ).
Reinforcing wire of the round profile having diameters 3,0-5,0 mm is supplied in coils of 1000 kg, diameters 3,0; 4,0 mm may also be supplied in coils having mass 1400 kg.
Overall dimensions of a coil having mass 1000 kg: height – 460 mm, internal diameter – 500/420 mm, external diameter – 850/820 mm.
Overall dimensions of a coil having mass 1400 kg: height – 650 mm, internal diameter – 5 00 mm, external diameter – 850 mm.
The reinforcing wire of the periodical profile is supplied in coils having mass from 1000 kg to 3000 kg.
Mass of a coil is determined according to the customer's demand.
| Weight of coil, kg | Inner diameter, mm | External diameter, mm | Height, mm |
| 1000 | 420 | 820 | 460 |
| 1400 | 600 | 870 | 750 |
| 2500 | 600 | 1080 | 750 |
| 3000 | 600 | 1120 | 750 |
Coils are tied with the steel metal strip in at least four places.
