What Are Electro-Galvanized Steel Sheets?
Electro-galvanized steel sheets are steel sheets coated with zinc to enhance rust and corrosion resistance, addressing a common vulnerability of steel plates. Known for its excellent workability, cost-effectiveness, and mass production suitability, electrically zinc-coated steel is prevalent in numerous industrial uses.
The two main types of electrically zinc-coated steel sheets are cold-rolled and hot-rolled. There aren’t specific composition regulations for these steel sheets; however, they are fundamentally steel. If the original plate before coating has composition regulations, those standards apply.
Uses of Electro-Galvanized Steel Sheets
Electro-galvanized steel sheets, derived from hot-rolled steel sheets, are softened by heating prior to rolling, offering superior workability. The process of hot rolling, which involves applying high pressure to heated materials, results in stronger metal crystals and a more tenacious metal. However, hot rolling can reduce dimensional accuracy due to thermal expansion, and the high-temperature metal surface may react with air oxygen, forming an oxide film and a non-glossy surface.
The thickness of electro-galvanized steel sheets typically ranges from 1.6 mm to 4.5 mm. Its mechanical properties include a tensile strength of at least 270 N/mm². The elongation percentage varies based on thickness, with different ranges for thicknesses from 1.6 mm up to 4.5 mm.
Due to its versatility and general utility, electro-galvanized steel sheets are utilized in a wide array of applications, including office equipment and audio devices.
