What material is galvanizing？

Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play the role of aesthetics and rust prevention. The main method used is hot-dip galvanizing. Galvanizing is an economical and effective anti-corrosion method that is often used. Zinc is soluble in acids and alkali, so it is called an amphoteric metal. Zinc changes little in dry air.

With the development of galvanizing process and the use of high-performance galvanizing brightener, galvanizing has entered the protection - decorative application from the simple protection purpose. There are two types of galvanizing solution: cyanide plating solution and cyanide-free plating solution. The cyanide plating solution is divided into micro cyanide, low cyanide, medium cyanide, and high cyanide. Cyanide-free plating solution includes alkaline zincate plating solution, ammonium salt plating solution, sulfate plating solution and ammonia-free chloride plating solution.
