Galvanizing is hotter is an easy and effective way of protection of steel structures against corrosion (rust) and mechanical damages.

Technological process of hot galvanizing consists of 6 stages:

- degreasing: at this stage removal from a surface of hardware and designs of fatty spots, oil and other synthetic stratifications which slow down is made and worsen digestion, reactions of zinc and metal of a basis interfere.

- etching - an important stage of preparation of a surface of hardware for galvanizing, at the same time happens removal from a surface of details of a rust and scale, and also chemical activation of a surface of steel (removal of an oxide film) without its damage,

- washing: during washing there is a washout of firm metal parts from a surface of products are zinced also prevention of transfer of solutions of hydrochloric acid in a fluxing bathtub,

- fluxing: it is a final stage of preparation of a surface which is necessary for drawing a protective layer on a surface of hardware. During fluxing oxides are removed and further are not formed on a metal surface before galvanizing,

- drying: during drying there is a removal of moisture from a surface of a metalwork. Heating of products happens to 100 degrees Celsius. This stage serves as temperature preparation for process of hot galvanizing,

- hot galvanizing: formation of a zinc covering due to reaction between metal and zinc which together form an alloy.

All processes happen in special bathtubs.
