What Is SGCC Galvanized Steel?
SGCC is a type of zinc-coated steel sheet, made by coating low-carbon steel sheets with zinc to enhance surface corrosion resistance.
Two types of hot-dip galvanization are applied to SGCC: non-alloy galvanization, where the base steel and zinc don’t alloy, and alloy galvanization, where iron from the base steel alloys with the zinc coating.
Uses of SGCC Galvanized Steel
SGCC is primarily used in:
- Building Materials: Roofing, walls, door frames, and structural elements.
- Automotive Components: Body panels, wheels, and muffler tanks.
- Electrical Equipment: Enclosures, frames, and covers.
- Home Appliances: Refrigerators, washing machines, and air conditioners.
Properties of SGCC Galvanized Steel
SGCC’s main properties include:
- Chemical Composition: Low levels of carbon, manganese, phosphorus, and sulfur.
- Corrosion Resistance: Zinc coating forms a protective oxide layer.
- Workability: Easily processed through cutting, bending, and welding.
- Stability: Resists deformation and degradation, ensuring long-term durability.
- Cost-Effectiveness: Affordable production process and materials.
Other Information on SGCC Galvanized Steel
Alloyed hot-dip galvanized steel sheets, formed by alloying iron and zinc, offer enhanced adherence and extended corrosion resistance compared to non-alloyed sheets. These sheets are characterized by strong zinc adhesion, finer coating grains, and improved paintability.
