Hot Dipped Galvanized vs Electro Galvanized

Which is better Hot-dip Galvanizing or Electro Galvanizing?

Both HDG and EG are produced by galvanizing hot-rolled coils or cold-rolled coils. The zinc coating protects the steel from atmospheric and water attack, and the thickness of the zinc coating determines the service life of the galvanized steel. The two types of galvanized steel have different focuses, so you can choose the right galvanized steel for your project based on budget, cost, finish, and application.

Surface: Hot Dipped Galvanized vs Electro-Galvanized

HDG: Surface with spangle, spangle size can be adjusted, and zero spangles galvanized steel can be customized.

EG: Smooth surface, no spangle.

Cost: Hot Dipped Galvanized vs Electro-Galvanized

HDG: Hot Dipped Galvanized is low cost, and high productivity.

EG: Higher production cost, lower productivity.

Use for: Hot Dipped Galvanized vs Electro-Galvanized

HDG: Suitable for outdoor, industrial areas, and corrosive applications.

EG: Suitable for indoor, highly decorative applications.

Process of Galvanizing in Wanzhi Group

Wanzhi Group has both hot-dip galvanizing and electro-galvanizing lines, mainly producing z30-z350g galvanized products.

Process of Hot Dipped Galvanized

The treated substrate, hot rolled steel coil or cold rolled steel coil, is immersed in a high-temperature zinc solution, which causes the steel to react with the zinc solution to form a zinc layer. This process results in a thicker and more durable zinc layer.

Process of Electro Galvanized

Prepared hot rolled coils or cold rolled coils are placed in an electrolyte solution, which electrochemically deposits zinc on the surface of the substrate. The electroplated zinc layer is more uniform and shiny.
