Electro galvanized wire
Hot dipped galvanizing is an immersion-plating processing in heating melting zinc liquid. The procedure is very quick to enable a thick and even coating layer to the wire surface. The allowed minimum thickness is 45 micron, the highest zinc coating is more than 300 microns. The steel wire going through hot dipped galvanizing has a dark color compared with electro galvanised wire. The hot dipped galvanised steel wire consumes much zinc metal, and on the base metal forming an infiltration layer, offering good corrosion resistance. Whether used under indoor or outdoor environment, the hot dip galvanizing surface can keep decades without breaking. Compared with Electro Galvanized Wire, hot dipped galvanised wire offers better corrosion resistance. It has thicker zinc coating compared with electro galvanizing processing and can be used for a longer service life. Wire gauge:0.7mm-6.5mm. Low carbon steel:SAE1006,SAE1008,SAE1010,Q195,Q235,C45,C50,C55,C60,C65. Elongation:15%. Tensile strength: 300N-680N/mm2. Zinc coating:30g-350g/m2. Characteristic: High tensile strength, small tolerance, Shiny surface, good corrosion prevention. Application:Widely used in industry, agriculture, animal husbandry, handicrafts, silk weaving, highway fence, packaging and other daily applications. Like as cable armouring, wire mesh weave. Production process for hot dipped galvanizing: Steel rod coil →Wire Drawing →Wire Annealing → Rust Removing → Acid Washing → Zinc Plating → Wire Coiling. Packing: inside plastic/outside weaving bag, also can be according to customer's requirements.

Hot dipped galvanized wire
Electro galvanised wire (cold galvanized wire) is made by means of wire drawing followed by heat treatment and electro galvanizing. The galvanizing is made with mild steel or carbon steel wire in the plating bath, through the electric current unipolarity making zinc plating gradually on the surface. The galvanizing speed is slow to ensure a uniform coating, with thin thickness, usually only 3 to 15 microns. The outward appearance of electro galvanised steel wire is bright, the corrosion resistance is poor, the wire will get rust in a few months. Relatively the cost of electro galvanizing is low than hot dip galvanizing. Wire diameter: BWG8# to BWG16#. Materials: Carbon steel wire, mild steel wire. Size range: 0.40mm-4.5mm Weight of Zinc coating: 20 g/m2- 70 g/m2 Electro galvanized wire process: Steel rod coil →Wire Drawing → Wire Annealing → Rust Removing → Acid Washing →Boiling → Zinc Feeding → Drying → Wire Coiling Applications: Electro galvanized wire used in communication equipment, medical devices, weaving wire mesh, brush, tightrope, filtered mesh, high pressure pipe, architecture craftwork, etc. Packing: Spool packing, Plastic inside & Hessain bag/P.P OutsideSpecification
