The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

2. Adjust the drawing process parameters of the water tank

Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.

Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.

Packaging: electric welding net general packaging for moisture-proof paper (color is mostly gray white, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter electric welding net, because the wire is relatively soft, coupled with small volume, customers often require packing processing, in order to prevent shipment caused by damage. The wire of electric welding mesh has straight, also has a wavy bend (also known as the Dutch net).

Hot drawing is the heating before the wire enters the die hole, mainly used for high melting point wire drawing; The temperature drawing is carried out by heating the heater to the range of temperature, mainly used for galvanized steel wire, difficult to deform drawing.
