Galvanized steel sheets play an important role in various industries, providing corrosion protection and increasing durability for various applications. Galvanized steel sheets are made by coating SPCC (cold rolled steel sheets) with zinc. This makes it the first choice for various forming processes such as bending and extrusion.
Material and manufacturing process:
SGCC is the abbreviation of hot-dip galvanized thin steel sheets, where S stands for Steel, G stands for Galvanized, C stands for Cold, and the second C stands for Common. It is made by immersing the cleaned iron parts in a molten zinc bath, and the steel reacts with the molten zinc to form an alloy film through the wetting effect of Flux.
SECC is electrogalvanized steel sheet, also known as EG material. It is a layer of zinc plated on the surface of the cold rolled sheet through an electroplating process.
Appearance and color:
The surface of SGCC steel sheet is bright white, with good metallic luster, and sometimes there are fine zinc flowers on the surface.
SECC steel sheet is uniform gray and has a relatively smooth surface.
Performance characteristics:
SGCC steel plate is rust-proof and weather-resistant, with excellent anti-corrosion performance, and the anti-corrosion effect in general environment can reach 30-50 years. It has strong adhesion, impact resistance, friction resistance, good long-term anti-corrosion effect, and no maintenance is required.
SECC steel plate also has anti-rust and corrosion resistance, but its formability and paintability are better than SGCC. However, in terms of mechanical properties, the tensile strength and yield strength of SECC are lower than SGCC.
Application areas:
SGCC is mainly used for parts of small household appliances that require good appearance. Due to its corrosion resistance and aesthetics, it is widely used in various occasions that require long-term anti-corrosion.
SECC has a wider range of applications, including office machines (such as copiers, computer cases, printers, etc.), buildings (doors, wall partitions, etc.), production machinery (agricultural machinery, industrial robots, etc.) and automobile manufacturing.
