🔥 Quality Is Not Inspected In. It’s Built In.

Every PPGI coil goes through a strict Quality Control System — from raw material to final shipment.

✅ Coating Thickness Control
✅ Paint Adhesion Test
✅ Bending & Forming Test
✅ Color & Surface Inspection
✅ Zinc/Al-Zn Coating Check
✅ Final Quality Inspection

The result?
🎯 Consistent color. Strong adhesion. Better forming. Longer service life.

We don’t just sell PPGI. We control every step behind its quality.

A roof is installed in days.

But it stays for decades.

That’s why every RAL6005 PPGI coil is inspected from production to packaging.

Beautiful color.
Strong adhesion.
Reliable quality.

Because every project deserves materials built to last.

Not all PPGI is created equal.

Anyone can paint steel.

But can it pass the tests?

Our RAL8015 PPGI is verified through:
✔ Coating Thickness Test
✔ Bending Test
✔ Stamping Test
✔ Final Surface Inspection

Because quality isn’t what you see.
It’s what survives every inspection.

Ready for roofing.
Ready for your next project.

Stop buying PPGI by price.

Buy it by this test.

One stamp.
One bend.
Zero paint peeling.

That’s the difference between cheap steel and reliable steel.

How do you know if a PPGI coil is really good quality?

A beautiful surface isn’t enough.

The real test begins after production.

We don’t just look at the color — we test how the coating performs under real stress.

🔹 Bending Test — Can the steel bend without the coating cracking or peeling?

🔹 Impact / Forming Test — Can the coating withstand deformation while remaining firmly bonded?

🔹 Coating Adhesion Test — After repeated rubbing, does the paint stay firmly attached without obvious color loss?

🔹 Surface Inspection — Is the color uniform, the surface smooth, and the coating free from visible defects?

Because PPGI will eventually be cut, bent, pressed and formed into roofing sheets and other products.

If the coating cannot survive these tests, a beautiful coil today may become a problem after processing.

Good PPGI isn’t just about how it looks.
It’s about how it performs.

Test it. Bend it. Rub it. Inspect it.

That’s how we select reliable PPGI before shipment.

Good coating should survive more than just a visual inspection.

Before shipment, our PPGI/PPGL steel is tested through stamping and bending to check how the coating performs under deformation.

During the test:
• No obvious paint peeling
• No cracking during bending
• Strong coating adhesion
• Good flexibility for further processing

Because for roofing, panels and other fabricated products, good color is not enough — the coating needs to stay where it belongs.

Quality you can see. Performance you can test.
