Steel rope wire of State Standard GOST 7372-79
Steel rope wire of State Standard GOST 7372-79 is designed for rope manufacturing and is also used in Egoza razor wire https://piranja.ua/en/catalog/barbed-wire manufacturing. High-carbon iron wire of GOST 7372-79 is produced from 0,2 to 5,5 mm in diameter, both galvanized and uncoated. At the customer’s request wire manufacture of intermediate diameter is permitted. Rope iron wire complies with the standards GOST 7372-79, DIN 2078, EN 10264-2, BS 2763. Under GOST 7372-79 standard there are following groups based on galvanized coating thickness: M – for moderate operation conditions, S – for severe operation conditions, SS – for super severe operation conditions. Under DIN 2078 standard thickness of galvanized coating is: uncoated – Vk, standard zinc-coating – noZn, densely galvanized – diZn. Under EN 10264-2 standard, wire is either uncoated or zinc-coated according to B class. Under BS 2763 standard rope wire is uncoated, drawn and galvanized according to Z class and A class.
Supply of wire of standards GOST 7372-79, DIN 2078, EN 10264-2, BS 2763
Rope wire of GOST 7372-79 is supplied depending on diameter and of diverse make. Rope wire from 0,2 to 0,65 mm in diameter is supplied in coils weighing 7-30 kg or in BS-60 reels. Rope wire 0,6-1,3 mm in diameter is shipped in coils up to 80 kg or in Z2, Z2S type reels. Rope wire from 1,3 to 3,0 mm in diameter is supplied in coils 100-150 kg each or in Z2 type reels and rope wire from 2,5 to 5,5 mm in diameter – in coils weighing 100-150 kg or in reels 1000 kg each. Non-galvanized rope wire is covered with preservation oil for protection against rust, besides rope wire which is 0,4 mm in diameter is covered with moisture-proof paper and packed in rigid package. Rope wire 0,4 to 1,0 mm in diameter is covered with moisture-proof paper and polymer film, and rope wire 1,0 mm in diameter and more is packed in polymer film or polypropylene fiber.
