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).
