Описание к видео Electro-Galvanized VS Hot-Dip Galvanized (HDG) - What's the Difference?

You are the owner or the engineer working on a project. A subcontractor approaches you asking if they can use galvanized steel, instead of hot-dip galvanized steel as called out in the specifications and the project drawings. He says, galvanized steel is cheaper and more readily available and that using it can save you time and money. How would you answer?

Do you know the difference between the two?

This video discusses the difference between electro-galvanizing (zinc electroplating or simply, galvanizing) and hot-dip galvanizing (HDG). It compares the two in terms of processing, appearance, cost, durability and corrosion protection, and application.
