✔ Superior rust protection
✔ Long lifespan (20-50 years)
✔ Easy to weld and form
✔ Cost-effective for industrial use
PPGI (Pre-Painted Galvanized Iron) is GI steel with an additional painted coating, offering both durability and aesthetic appeal.
✔ Enhanced weather resistance
✔ Wide range of colors & finishes
✔ No need for additional painting
✔ Ideal for architectural and decorative uses
| Factor | GI Steel | PPGI Steel |
|---|---|---|
| Corrosion Resistance | High | Very High |
| Appearance | Metallic (zinc-coated) | Color-coated |
| Cost | Lower | Higher (but saves painting costs) |
| Best For | Structural, industrial | Architectural, decorative |
GI Steel: Roofing, automotive parts, electrical enclosures
PPGI Steel: Building facades, appliances, signage
Q: Is PPGI more durable than GI?
A: Yes, due to its extra paint layer, PPGI offers better UV and corrosion resistance.
Q: Can GI steel be painted later?
A: Yes, but surface preparation is needed for proper adhesion.
Q: Which is cheaper, GI or PPGI?
A: GI is cheaper upfront, but PPGI may save long-term maintenance costs.
GI steel is ideal for industrial uses, while PPGI is perfect for projects requiring both durability and aesthetics. Choose based on your project’s needs for cost, appearance, and longevity.
