Prepainted GI steel coil, also known as PPGI (Prepainted Galvanized Iron), refers to a color coated galvanized steel sheet in coil form. Galvanized steel undergoes a chemical process to prevent corrosion. It is coated with layers of zinc oxide, as zinc is a protective metal that resists rusting. The zinc coating not only provides corrosion resistance but also gives the steel a durable and scratch-resistant finish, which is aesthetically appealing to many. Galvanized steel is widely used in outdoor, marine, and industrial applications, making it an essential component in various fabrication projects.

Tinplate Coil, also known as electroplated tin steel sheets, refers to cold-rolled low-carbon steel sheets or strips that are coated with commercial pure tin on both sides. Tin serves as a protective layer, preventing corrosion and rust. This material combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin. Tinplate Coil possesses several advantageous properties, including corrosion resistance, non-toxicity, high strength, and good ductility. It offers excellent protection against corrosion while maintaining a safe and non-toxic packaging material. Tinplate packaging has a wide range of applications in the packaging industry due to its ability to provide effective sealing, preservation, light-proofing, durability, and unique metal decoration charm.

A galvanized coil is a thin steel sheet that undergoes a process where it is immersed in a molten zinc bath to create a layer of zinc on its surface. It is primarily produced through continuous galvanizing, a process in which the rolled steel plate is continuously submerged in the molten zinc bath to form a galvanized steel plate. There is also alloyed galvanized steel sheet, which is produced using the hot-dip method. After exiting the zinc bath, it is immediately heated to approximately 500°C to create an alloy coating consisting of zinc and iron. Galvanized coils exhibit good coating adhesion and weldability due to the zinc layer adhering well to the steel surface. The galvanization process provides corrosion resistance and protects the underlying steel from environmental factors.
