pattern perforated metal sheet

To stop normalizing or soxhlet processing of wire rod, spheroidization annealing is used instead of large specification. In the middle, especially before the waste drawing process, the thermal disposal of soxhlet is widely used. Prevent decarbonization during thermal disposal. After hot disposal, sulfuric acid or hydrochloric acid pickling is used to remove the iron sheet. Coating can be used to dip lime, phosphating, borax treatment or copper plating.

Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but relies on its own raw materials for corrosion resistance, so there will be no chemical reaction.

In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.

The front and back twist barbed wire costs less than 30 cents per meter, and the corresponding No. 12 hot-dip galvanized barbed wire costs 5 cents per meter. No matter in terms of service life, tensile strength, and anti-rust effect, it is no worse than No. 12 iron wire
