Galfan wire is a special galvanized annealed wire with a hot dip coating of a metal alloy (5% aluminum and 95% zinc alloy) material. It is especially suitable for outdoor, humid and oceanic climate. The alloy zinc coating sprayed steel wire has strong ductility and deformability. The galfan wire can be processed technically by deforming, winding or bending without cracking and shedding of zinc layer. It is used primarily for mesh gabions and fencing processing.
The Galfan coating provides enhanced corrosion resistance and durability for the steel wires, making Galfan coated wire well-suited for various applications, particularly in industries where corrosion protection is crucial.
Processing
Zinc-aluminum alloy coated steel (Galfan) wire is made of 6.5 mm low-carbon steel wire by drawing, high-temperature annealing, pickling and rust removing, hot-dip galvanizing with zinc-aluminum alloy.
Wire diameter ranges from 1.24mm-5.5mm.
Galfan coatings can be Al 5%, Zinc 95%, or Al10%, Zinc 90%.
Corrosion resistance: about 2-3 times that of ordinary galvanized steel wire
Coating material: Zinc aluminum alloy
Coating process: Thermal spraying
