Electro Galvanized VS Hot Dip

There are two different ways to put a protective zinc coating on steel or iron to stop corrosion: electro-galvanization and hot-dip galvanization. Each has advantages that are specific to a certain application. Here’s a summary:

Electro-Galvanization: This process creates a smooth and glossy finish on the steel surface by depositing a thin coating of zinc via electrolysis. It works well indoors or in settings where there is little exposure to the outside. Compared to hot-dip galvanization, the coating is thinner and less durable, making it more appropriate for less demanding situations even if it provides great initial corrosion protection.

Hot-Dip Galvanization: This method produces a stronger and thicker protective coating by submerging steel in molten zinc at a temperature of about 450°C. The final coating offers exceptional resistance against rust and corrosion.
