1. Preparation. For creating galvanized steel, ordinary steel is dipped in a pool of molten zinc. This is known as hot-dipping. Another method used for creating the coating in many cases is electro-dipping, which is a process in which the steel is dipped in an electrolyte solution containing zinc and makes use of electrolysis to create the coating.
For more than 150 years, hot-dip galvanizing after fabrication has been specified to combat steel corrosion in the harshest environments throughout various markets. However, new technologies and creative chemistries evolve the specification and use of hot-dip galvanized steel constantly as new markets emerge.

Galvanized Steel Pipe, is stocked in A53 Tested Pipe up through 6" sch 40 and A500 for sizes 8" to 12" diameters.All pipes have been hot dipped in a zinc rich galvanizing process. Galvanized pipes are a lower cost alternative to stainless steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.
Hot dip galvanized steel is used in applications where steel may be exposed to weather, but where stainless steel is too expensive. Steel to be galvanized is first washed and chemically treated to remove dirt and oxidation from the surface of the metal. It is then dipped in a kettle of molten zinc at 815-850F (435-455C).

Hot-dip galvanization is a form of galvanization.It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 C (840 F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2) to form zinc oxide (), which further reacts with carbon dioxide (CO 2 class 1 class 2 class 3 hot dipped galvanized steel pipe
