Uses Of Electro-galvanized steel sheets

Steel sheets are used in a remarkably wide range of applications in everyday life. The growth of coated steel sheets has been especially astonishing in fields where improved product durability and cost reduction by process omission are strongly required. Today, coated steel sheets are widely used as corrosion-resistant steel sheets with excellent economy, mainly in fields such as automobiles, electrical appliances, and OA equipment. APC has devoted great effort to the development and production of various types of coated steel sheets, taking advantage of the company’s state-of-the-art manufacturing equipment and technologies accumulated over many years. APC’s electro-galvanized steel sheets have responded to market needs that are constantly changing and increasingly diverse and sophisticated with extensive chemical conversion-treated products suited to their attractive appearance. In the future, we appreciate customers’ understanding of the outstanding properties of APC products and we look forward to serving you with the best possible product for every application.


  • GLs are 3~6 times more corrosion-resistant compared to GI, but have a similar level of processability and weldability and can replace GIs, in particular are most suitable when replacing GIs that require thick galvanized layers and high corrosion resistance.
  • Only galvanized steel sheet is used for roofing and walls without painting because of its unique silver spangles beautiful appearance and high corrosion resistance, and is used as a cool roofing material because of its excellent heat reflection qualities.
  • Can replace aluminum gilded steel sheets because of certain purposes of its electrical conductivity and its heat-resistance qualities even at high temperatures that do not exceed 315℃.
  • Has greater surface hardness than GIs, and is much more wear-resistant.
  • Corrosion resistance increased more with resin-coating treatment, which enables roll forming or press forming without the spraying of processed oils.
