PPGI Q235
Robust Steel Solutions for Demanding Applications
Our Q235 galvanized steel coils and PPGI/PPGL color-coated sheets combine structural durability with aesthetic versatility, engineered for construction, industrial machinery, and architectural projects.
Core Advantages:
✔ Q235 Base Metal: Yield strength 235–355 MPa (GB/T 700 standard)
✔ Advanced Coatings: 60–275 g/m² zinc layer (hot-dip) or 50–220 g/m² Al-Zn (PPGL)
✔ Surface Finishes: Anti-fingerprint, chromated, or oiled options
✔ Precision Thickness: 0.1–5.0mm (±0.03mm tolerance)

- Custom palletization for container optimization
Quality Assurance:
- ISO 9001-certified production lines
- Third-party SGS/BV test reports available
Technical Differentiation
→ Galvanized vs. Prepainted:
- While Q235 galvanized excels in raw strength, PPGI adds decorative weather resistance.
- PPGL’s 55% Al-Zn coating provides superior heat reflection vs. PPGI.
