Galvanized steel sheets refers to a flat-rolled steel product that has been coated with a layer of zinc through a hot-dip galvanizing process. This process involves immersing the steel coil in a bath of molten zinc, which forms a protective zinc coating on the surface of the steel.
Galvanized steel sheet is typically made from low carbon or mild steel, which is suitable for the hot-dip galvanizing process. The choice of substrate may vary depending on the specific application and desired mechanical properties.
The primary purpose of galvanizing is to provide corrosion resistance to the steel. The zinc coating acts as a barrier that prevents moisture and oxygen from reaching the underlying steel, thereby protecting it from rust and corrosion. The thickness of the zinc coating can vary based on the specific requirements and can be designated using terms such as Z80, Z120, or as per the applicable standard.

Gi Galvanized Sheet
Hot-dip galvanized sheet also has a number of other benefits:
It's durable: Hot-dip galvanized steels is incredibly durable, meaning it won't corrode or degrade over time like other materials can. This makes it ideal for use in ductwork that will be subject to high temperatures or harsh conditions.
It's fire resistant: Galvanized steels is non-combustible, making it an excellent choice for use in ductwork near heat sources or in buildings where fire safety is a concern.
It's easy to work with: Galvanized steels is relatively easy to cut, bend, and weld, making it a good choice for DIY projects or for use in custom applications.
It's affordable: Hot-dip galvanized steels is one of the most affordable options for ductwork material, making it a great choice if you're working with a limited budget.
Galvanized Steel Sheet Types
According to the processing method, we divide galvanized steel into the following categories:
1. Hot-dip Galvanized Steel Sheet
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steels sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Steel Sheet
Electro-galvanizing is a process of applying a layer of zinc to steels through electroplating, with a saline anode and steels conductor. It is able to enhance the corrosion and heat resistance of steels. Also, it makes steels sheets more good-looking.
