PPGI Steel Coil

PPGI (Pre-Painted Galvanized Iron): This refers to a color-coated pre-galvanized steel coil. It uses hot-dip galvanized steel as the substrate. After surface pretreatment (degreasing, cleaning, chemical conversion treatment, etc.), one or more layers of organic coating are applied to the surface, which are then cured by baking.

Our PPGI Steel Coil (Pre-painted Galvanized Iron) is a highly versatile and cost-effective material used globally in various sectors, from large-scale roofing projects to appliance manufacturing. By combining the foundational rust protection of galvanization with a high-performance color coating, PPGI coils offer both durability and aesthetic appeal. 
Key Features & Advantages:
  • Dual Layer Protection: The galvanized substrate provides cathodic protection against rust, while the organic paint coating acts as a barrier against weather, UV rays, and chemical exposure.
  • Aesthetic Versatility: We offer a vast selection of RAL colors and surface finishes (matt, glossy, wood grain, camouflage) to match any project requirement.
  • Formability & Workability: Our coils are produced to ensure excellent flexibility and formability, allowing them to be corrugated, roll-formed, or bent into complex shapes without damaging the paint coating.
  • Cost-Effective Solution: PPGI offers a long lifespan and requires minimal maintenance, providing excellent long-term value for B2B procurement. 
Primary Applications:
  • Construction: Corrugated roofing sheets, wall panels, garage doors, and sandwich panel insulation materials.
  • Home Appliances: Refrigerators, washing machine panels, air conditioner casings.
  • Furniture: Filing cabinets and office partition walls.
