Galvanization

Description

Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. We use electro-galvanizing method, which is galvanized through electrode reaction. The zinc ingot is used as the anode, the zinc atoms lose their electrons and become ions and dissolve into the electrolyte. The steel strip is used as the cathode, the zinc ions gain electrons on the steel strip and are reduced to zinc atoms that are deposited on the surface of the steel strip to form a coating.

Design considerations for Galvanization

Galvanization can potentially cause hydrogen embrittlement in certain materials, which can weaken the material and make it more susceptible to cracking or failure.
Galvanization typically results in a silver or metallic finish, which may not be suitable for all applications or design preferences.
Galvanization can only be applied in relatively thin layers, which can limit its usefulness in certain applications.

The Justway Galvanization process

Galvanization is a versatile and effective surface finishing process that provides numerous benefits for a variety of applications. Let’s break down the basic steps for Galvanization a part:
