  • Highly corrosion-resistant/highly workable plated steel wire, plating bath composition, method for producing the plated steel wire and wire netting product
    Patent number: 7601433
    Abstract: A plated steel wire having a plated layer and an intermediate layer is characterized in that a content of manganese contained in both the plated layer and the intermediate layer is 0.02-0.30% in terms of average mass percentage, a content of aluminum is 8-25% in terms of average mass percentage, and a content of zinc and inevitable components is 74.70-91.98% in terms of average mass percentage, and that a total deposition amount of the intermediate layer and the plated layer per unit area of the steel wire surface is set to 700-1000 g/m2. The plated steel wire has excellent corrosion resistance and excellent workability, with the increased total deposition amount of the plated layer and the intermediate layer.

  • Wire material plating equipment
    Patent number: 7220316
    Abstract: An apparatus for plating a wire material is provided in which a range of the plated layer where the temperature is high and flowability is large, thus, easily generating thickness deviation, and a range of the plated layer where the temperature is low and the flowability is small, thus generating thickness deviation only with difficulty are allowed to cool in an appropriate manner, respectively, whereby a plated wire material whose thickness deviation is not more than 2.0 can be produced with high productivity in a stable manner.
