Prepainted Galvanized Galvalume Steel Coil

PPGI Coil VS PPGL Coil    PPGI (Pre-painted Galvanized Iron) and PPGL (Pre-painted Galvalume) are two types of coated steel coils used in various applications. The main difference between PPGI and PPGL is the type of coating material used. PPGI Coil: PPGI is coated with a layer of zinc to protect the steel from rust and corrosion. The zinc coating is applied using a hot-dip galvanizing process, which involves dipping the steel coil in a bath of molten zinc. PPGI coils are widely used in construction, automotive, and appliance industries due to their excellent corrosion resistance and durability. PPGL Coil: PPGL is coated with a layer of zinc, aluminum, and silicon to provide superior corrosion resistance and heat resistance. The coating material is applied using a continuous hot-dip process, which involves passing the steel coil through a molten bath of the coating material. PPGL coils are commonly used in roofing, cladding, and other outdoor applications. In summary, wh…
