Correction is the hot galvanized wire or cold galvanized wire secondary treatment, the surface after correction is smooth and shiny, and the tensile strength is stronger, so that it is not easy to break. Now it is usually used for screen industry will be changed, which can improve the quality. In addition, clothes rack, communication, high voltage line will be changed to prevent breakage.

Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.

Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.
