Hot-dip galvanizing works well for outdoor structures and places with high moisture. You get a coating thickness that ranges from 35 μm to 275 μm. This thick layer stands up to harsh weather and chemicals. When you choose hot-dipped galvanized steel, you invest in long-term durability and safety.

Electro-Galvanizing

Electro-galvanizing uses a different approach. You apply zinc to the steel using an electric current. This method creates a thinner zinc layer, usually between 5 μm and 15 μm. Electro-galvanizing gives you a smooth, even finish. You often use this process for indoor applications or where appearance matters more than heavy-duty protection. The thinner coating offers less corrosion protection than hot-dip galvanizing, so you should avoid using it in harsh outdoor environments. You still get some protection from rust, but the main benefit is the clean look and precise coating.

Here is a table that compares hot-dip galvanizing and electro-galvanizing:

Zinc Coating and Corrosion Protection

The zinc coating is the key to corrosion protection in galvanized steel frames. When you use the galvanizing process, you create a barrier that blocks moisture and chemicals from reaching the steel. The zinc also acts as a sacrificial layer. If the coating gets scratched, the zinc will corrode first, protecting the steel underneath. This self-healing property makes hot-dipped galvanized steel a smart choice for construction.

You can see the range of zinc coating thicknesses in different types of galvanized steel sheets:

Note: Thicker zinc coatings give you better corrosion protection and longer service life. Hot-dipped galvanized steel usually offers the best results for outdoor and industrial use.
