Wire is coated with continuous thin lay of conserving oil protecting it from corrosion. It can not be oiled on buyer's request.

Wire by the diameter:
- 0,2 - 0,65 mm is produced in coils with weight 7 - 30 kg or BS-60 spools;
- 0,6 - 1,3 mm is produced in coils up to 80 kg or in coils with type Z2, Z2S;
- 1,7 - 3,5 mm is produced in coils "rosette" with weight 500-800 kg;
- 1,3 - 3,0 mm is produced in coils with weight up to 100 - 150 kg or in coils with type Z2;
- 2,5 - 7,0 mm is produced in coils with weight 600 - 1000 kg.
CoiIs, bundles, spools are packed by waterproof paper and polymeric film.

Note: on the customer's request the production of wire of the intermediate diameters is allowed.
