PPGI Coil
Versatile Steel Solutions for Industrial & Architectural Needs
Our galvanized steel coils and PPGI/PPGL pre-painted sheets deliver exceptional durability and design flexibility, serving industries from construction to automotive manufacturing. With tailored coatings and precision engineering, these materials excel in harsh environments while maintaining aesthetic appeal.
Core Advantages:
✔ Dual Substrate Options:
- PPGI: Galvanized steel base (Zinc coating)
- PPGL: Galuminized steel base (55% Al-Zn alloy coating)
✔ Enhanced Protection: 60–275 g/m² zinc or 50–220 g/m² Al-Zn coatings
✔ Surface Finishes: Anti-fingerprint, chromated, oiled, or skin-passed
✔ Thickness Precision: 0.1–5.0mm (±0.03mm tolerance)

- Steel edge guards + cross-binding straps
- Custom coil IDs for traceability
Quality Assurance:
- ISO 9001-certified production
- Third-party SGS/BV test reports
Technical Comparison
→ Galvanized vs. PPGL:
- While galvanized coils prioritize cost efficiency, PPGL adds thermal reflectivity (85% solar reflectivity).
- PPGI suits indoor use; PPGL excels in coastal/industrial zones.
