hot dip vs electro galvanizing

[starcentral]

I'm putting my docks in soon and will be using some new chains to anchor.

I saw two types of galvanizing, which is better really?

hot dip vs electro galvanizing?

Electrolytic galvanizing produces a very thin coatings of zinc.

Hot dip is produced by dipping the material in a bath of molten zinc to deposit a thick coating of zinc.

Galvanizing is a sacrificial coating, meaning that it “wears off” overtime. Where long term protection is the goal, thicker is better

On roofing nails-hot dip holds better and lasts longer. Electro gal. rusts faster.

Yup just re-did a roof and used hot dipped galvanized nails as a result of these comments
