Galvanized Wire | Jagdamba Steels

GALVANIZED WIRE

While manufacturing G.I. Wires(GALVANIZED WIRE), annealing, picking procedures are mostly carried out. Following the high-tech methodology, G.I. Wires are produced through H.B. Wires. Galvanizing methods are dome with 99.9 percent pure electronic zinc. Prior to galvanizing, the activities like pickles and rinse are carried out thoroughly and flex coating is applied in the wires which helps zinc to stick in the base metal effectively. With the quality recognition of IS 4826/1979 and NS 163,165/ 645. Jagdamba has been manufacturing G.I. Wires.

Following tests are carried out in wires:

  • Measurement of Zinc coat
  • Equality of Zinc coat
  • Stickiness of Zinc coat
  • Tensile strength
  • Wrapping test
