Z15 Z30 0.4mm 1mm ST37 SPCC SGCC Cold Rolled Zinc Coated G60 Galvanized Steel Coils
Galvanized Steel Coil Introduction
Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer. This bonding layer is formed by a diffusion process while the heated steel is in contact with molten zinc. We can provide hot dipped galvanized steel sheet & coil to meet your ASTM requirements with customer-driven surface finish options.

A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet. Sacrificial or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.
Shandong Fulilai Steel Group is a leading supplier of galvanized steel sheet & coil. Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.
The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.
Advantages of Galvanized Steel
The main advantage of galvanized steel is its corrosion resistance. The zinc coating serves as a barrier between the steel and the environment and will sacrifice itself in order to protect the underlying steel; Meaning the zinc will degrade much sooner than the steel itself. Additionally, it offers good processability and formability.

Applications of GI Sheet&Coils
The applications of Galvanised Steel Coils are numerous, especially in fabrication and manufacturing environments. Construction workers mostly use Galvanised Coils for Roofing applications. They are also used as sheet metal brakes in buildings.The biggest use of GI Sheets is for construction projects in homes, offices, and factories. They resist corrosion,heat, and are easily installable, making them best suited for roofing. They are also used in the production of corrugated panels, drywall panel profiles, ventilation systems, etc.
