What is the standard of galvanized steel wire?

There are many kinds of steel, such as steel pipe, steel plate, steel bar and steel wire, which are important building materials and industrial raw materials. As an important material, steel needs corresponding properties in application. The general properties of steel require strength, tensile strength and corrosion resistance. The biggest disadvantage of traditional steel is that it is very easy to rust and be corroded. In order to improve the corrosion resistance of steel, people have developed zinc plating technology for steel. At present, there are two commonly used galvanizing methods: hot galvanizing and electro-galvanizing, and all kinds of galvanized steel can be basically divided into two categories: hot galvanizing and cold galvanizing. The following rabbit will introduce galvanized steel wire and its production standard to everyone.

I. About galvanized steel wire

Steel wire is one of the important steel products, and its main functions in construction and industrial production are hanging, binding, drawing and making steel wire mesh. Galvanized steel wire is a kind of galvanized steel wire, which has good corrosion resistance and general steel wire performance, and can meet various application requirements. According to different galvanizing methods, galvanized steel wire can be divided into hot galvanized steel wire and cold galvanized steel wire. Because of the different galvanizing methods, the performance and appearance of these two kinds of galvanized steel wires are quite different, and their uses are also different.

Galvanized steel wire is galvanized in high-temperature molten zinc, and a zinc-iron alloy layer is formed before the galvanized layer is formed. It is precisely because of the existence of this zinc-iron compound that hot-dip galvanized steel wire has more outstanding corrosion resistance. Cold galvanized steel wire, that is, galvanized steel wire, is directly coated with zinc layer on the surface of steel wire by electroplating technology without chemical reaction. Therefore, the thickness of galvanized steel wire can be chosen at will, and the surface of steel wire looks more beautiful. However, due to the lack of zinc-iron alloy layer, the corrosion resistance of galvanized steel wire is much worse than that of galvanized steel wire.

Second, the standard of galvanized steel wire

Like other steel products, the production, manufacture and inspection of galvanized steel wire have corresponding standards, but compared with ordinary steel wire, the standards of galvanized steel wire also include the standards of galvanized layer. The standards of galvanized steel wire include galvanized wire rope monofilament, galvanized layer weight, copper sulfate test times and time, and each regulation has corresponding standards. Different social development periods have different standards for galvanized steel wire. For example, the current standard of galvanized steel wire in China is GB/T171KLOC-0/-2007, which is also improved and revised on the basis of the original standard.

The standard of galvanized steel wire is also a process of continuous improvement and development. At different stages of economic development, our requirements for galvanized steel wire are different, and the production technology of galvanized steel wire is also developing and progressing. Therefore, a standard must be revised and improved after being used for a period of time.

About galvanized steel wire and its standard rabbit, I will introduce it here, hoping to help you. Finally, I remind you that manufacturers should strictly abide by the production standards of galvanized steel wire and produce qualified galvanized steel wire.
