What is a galvanized sheet and what are the types of?
Galvanized steel sheet is a regular steel sheet with a protective layer of zinc that makes it resistant to moisture penetration and exposure to air. Such a protective coating can be applied to only one or both sides of a steel sheet. The thickness of the protective coating may vary depending on the use of the galvanized sheet and the expected humidity level of the environment.
Galvanized sheets
Galvanized iron sheet: It is the same iron coated with zinc filler.
Galvanized steel sheet: The same steel coated with zinc metal. is.
methods of producing Galvanized sheets
Galvanic method
The process of applying zinc metal (Zinc) on the surface of iron or steel using an electrolyte solution is called the galvanic method.
Galvanizing using From high temperature
This method is to cover a metal (usually iron or steel) with a layer of zinc by immersing the product in a bath of molten zinc with a temperature of about 460 degrees Celsius.
< b> Galvanizing using low temperature
Covering a metal surface with a special composition containing zinc powder is called galvanizing method using low temperature.
Method Galvanizing is a galvanizing method that involves the use of zinc powder (processed at a high temperature of 300-450°C) or zinc vapor (with a temperature of 800-900°C).
p> Galvanizing with zinc spraying
The zinc spraying method for galvanizing the surface is the same process of dusting steel or iron with zinc by a special technical gun.
Dynamic galvanizing Gas
In this method, zinc coating is placed on the surface of the metal using an ultrasonic jet stream.
The main characteristics of the classification of galvanized sheets
• Special use area (profile, construction of metal structures, pipes, etc.)
• Chemical composition of coating materials (pure zinc, or alloys such as zinc-iron-zinc, aluminum-aluminum zinc-zinc, magnesium, etc.)
• thickness and weight of galvanized protective coating
