What is a galvanized steel sheet? What types are there?
Steel products roll into thin sheets to create galvanized steel sheets. Then a thin layer of zinc is added on the outside by the hot-dip or electrolysis method.
A galvanized steel sheet is produced in flat sheet or coil form. The main component of this type of sheet is zinc (hard zinc and soft zinc). With the zinc coating on the surface, the galvanized sheet is less susceptible to rust due to environmental factors.
Based on the galvanizing method, this steel is divided into 2 types:
- Hot Dipped Galvanized Steel Sheet
- Electro Galvanized Steel Sheet
Among them, hot-dip galvanized steel sheets are the most commonly used. This is because the zinc coating will be thicker, more durable, and have a lower price than an electrolytic galvanized sheet. Therefore, in today’s article, we will focus on hot-dip galvanized sheets. Specifically, we will provide detailed hot-dip galvanized iron sheet price quotes below.

Galvanized steel sheet production process
- Step 1: Uncoiling. The steel coils are fed into the machine to uncoil into strips, long steel strips.
- Step 2: Cleaning the steel strip
- Step 3: Putting it into the annealing furnace without oxygen to reheat
- Step 4: Dipping in the plating tank
- Step 5: Drying and cooling the steel strip
- Step 6: Checking and evaluating the thickness of the plating layer
- Step 7: Rolling the rolling machine to make the steel strip smooth after plating
- Step 8: The steel strip is coated with chemicals, dried, and then coated with electrostatic oil to protect the surface.
- Step 9: Rolling
