JIS G3302 Certified PPGI Coils - Color-Coated Steel For HVAC Appliance Manufacturing


JIS G3302 Certified PPGI Coils are precision-engineered for ​HVAC systems and ​appliance manufacturing, combining ​corrosion resistance, ​thermal stability, and ​aesthetic versatility. Compliant with Japan’s rigorous ​JIS G3302 (SGCC) standard, these coils feature a ​hot-dip galvanized base (Z22–Z27) and ​15–25µm polyester/polyurethane coatings, ensuring durability in humid, high-temperature environments. Available in ​0.4–2.5mm thicknesses and ​600–1,250mm widths, they are optimized for air ducts, refrigeration units, and premium appliance casings.

Key Advantages:

  • JIS G3302 Compliance: Guarantees consistent zinc coating (20–275g/m²) and bendability (0T–1T).
  • Thermal Performance: Withstands -30°C to 120°C without coating cracking (tested per ASTM D2794).
  • Hygienic Surfaces: Smooth, non-porous coatings resist mold, bacteria, and chemical cleaners (pH 1–14).
  • Color Precision: 200+ pre-coated RAL/Pantone shades with ±0.5ΔE color accuracy.
  • Eco-Friendly: Halogen-free, RoHS-compliant coatings + ISO 14064 carbon-neutral production.
  • Fast Fabrication: Pre-punched holes, laser-cut edges, and CNC-compatible tolerances (±0.1mm).
