Knitting is also divided into two types, one is the ordinary knitting type, the other is the knitting type of embossing. Embossing is not simply used for knitting, but patterns can also be woven to add beauty. In short, it is a variety of steel wire as raw materials, through the professional screen material technology processing. It is widely used, mainly in construction.

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. With the rapid development of market economy, all walks of life are improving the production process and quality of products, galvanized iron wire industry is of course no exception. But because of the variety of galvanized iron wire, its characteristics and production technology are not the same.

Galvanized wire is immersed in heated molten zinc, the production speed is fast, the coating is thick but uneven. The thickness of 45 microns allowed by the market, the color is dark, the consumption of zinc metal is more, and the matrix metal is formed into an infiltration layer, and the corrosion resistance is good. The hot dip galvanizing can be maintained for decades in the outdoor environment.

Sodium and magnesium contain less combustible impurities, and when extinguished, they simply glow. Galvanizing belongs to the electrochemical processing process which is widely used on the surface of steel. So it is, first of all, because zinc coating (especially after supplementary processing, such as chromate treatment and phosphating) resistance to atmosphere and water is more stable, and the galvanized process itself this is cheaper and simple.
