Galvanized steel wire of State Standard GOST 9850-72

Galvanized steel wire for Egoza razor wire

For Egoza razor wire production wire of State Standard GOST 9850-72 is also used, designed for production of uninsulated steel-aluminium and steel-bronze wire cores. This type of wire has high spring properties as is produced of high carbon concentrated steel and has high quality galvanized surface coating which protects wire against rust. Egoza reinforced barbed tape manufactured on the basis of State Standard GOST 9850-72 wire has a long-term service life, high strength and ensures effective perimeter protection.

Wire of GOST 9850-72 is manufactured of diameter from 1.85 mm to 4.5 mm and has three classes of strength and two types of galvanized coating. For Egoza razor wire manufacturing, wire of State Standard GOST 9850-72 of 2.2 mm diameter is used, with galvanized coating for severe atmospheric conditions and maximum tensile strength. Set of properties of GOST 9850-72 wire allows of high quality Egoza production on its basis and with high performance properties – durability, strength and efficiency.
