Do You Know What Is Galvanized Steel Coil?


Galvanized Steel coil is usally briefly named for GI.In fact,GI is full name Galvanized Iron.GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel,  PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.


Galvanized Steel coil is defined as a carbon steel coil coated with zinc on both sides. Galvanized Steel Coil Importer produce galvanized steel with two main processes: continuous hot dip galvanizing and electrogalvanizing

The hot dip process includes passing the steel through a molten zinc bath, and the electrogalvanizing process includes applying zinc through electrolytic treatment. As a result, the zinc layer is firmly adhered to the base metal through the iron-zinc bonding layer. Our hot-dip galvanized products are manufactured in accordance with specifications, and our electro-galvanized products comply with the specification.


Galvanizing is one of the most effective and economical methods for protecting bare steel from corrosive environments. Zinc is not only a barrier between steel and the environment, but also sacrifices itself to protect the steel plate below. When two different metals are in contact and coupled with water and oxygen, sacrifice or current protection occurs. Zinc preferentially corrodes iron in steel. This protection prevents corrosion of the steel in areas not covered by zinc. Therefore, the diffusion of corrosion from cutting edges, drilling holes, etc. is minimized.


Many people know what galvanized steel is. It is used for a variety of applications from HVAC piping systems to garden barrels. Home decorations to the trash. The shiny finish on the surface makes it visually appealing, but it is also more durable and corrosion resistant.So, how is galvanized steel made? Where did the sequins come from? Let's find out.


Galvanized steel is carbon steel coated with zinc. The most common galvanizing method is the hot-dip process. The hot dip process involves immersing carbon steel in a molten zinc bath (approximately 680 degrees Fahrenheit). When the material is removed from the zinc bath and cooled, it reacts with oxygen in the air. This reaction causes zinc to become part of the steel (iron-zinc alloy bond). The new surface finish seems to have a crystalline finish or a bright finish.

Galvanized Steel Coil can be customized according the custom’s different requirments, such small spangle ,zero spangle ,big spangle ,checkered ,zinc coating, they can meet all the customer’s different needs.Galvanized steel coils are ideal options for constructing strong roofing systems. There are numerous added features associated with the amazing roofing systems.
