Prepainted Galvanised Steel Coil / PPGI / Corrugated Roofing Sheets Coil

Galvanized steel is designed to prevent the steel plate surface from corrosion and extend its service life. This is achieved by coating the steel plate surface with a layer of metallic zinc. Steel plates coated with zinc are referred to as galvanized sheets.

According to the production and processing methods, they can be categorized as:

  • Hot-Dip Galvanized Steel: Produced by immersing a thin plate in a molten zinc bath, which allows a layer of zinc sheet to adhere to its surface. A continuous galvanizing process is typically adopted, running the steel plate continuously through the melt zinc plating tank.
  • Alloyed Galvanized Steel: Made using the hot-dip method but heated immediately after processing to approximately 500°C. This forms an alloyed membrane of zinc and iron, yielding a galvanized sheet with excellent coating characteristics and weldability.
