Application of Galvanized Steel Coils SGCC
1. Petrochemical: Hot dip GI coil SGCC is often used to protect petrochemical equipment from corrosion, such as pipes, valves, flanges, pumps, etc.
2. Construction field: Hot dip GI sheet SGCC can be used to protect building structures from corrosion, such as steel bars, steel plates, scaffolding, etc.
3. Light industry: Hot dip GI steel coil SGCC can be used for various metal products in the light industry, such as pens, hardware, furniture, etc.
4. Aerospace: Hot dip steel coil SGCC is widely used in the aerospace field to protect aircraft, rockets and other aviation equipment from corrosion.
SGCC GI steel coil and SGCC GI steel sheet are synonymous with durability, strength and versatility. Combining the superior properties of galvanization with the ability to create thin, lightweight materials, galvanized steel has become the preferred choice across a variety of industries.
Hot-dip galvanizing reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating.The identification of Japanese steel plate grades: SGCC, HOT-DIP GALVANIZED STEEL is Hot Dipped Galvanized Steel Coils or Hot Dipped Galvanized Steel Sheets.
Galvanizing is an economical and effective antirust method which is often used.Also known as hot dip galvanized steel coil SGCC (galvanized iron), this type of steel is made by dipping coils of cold-rolled or hot-rolled steel into a bath of molten zinc, creating a protective layer that prevents corrosion and extends the life of the material.
SGCC (Steel Grade Coating Composition) is often used as a quality benchmark for evaluating the efficiency of hot dip galvanized steel coils and sheets.
