Frequently Asked Questions

What is the difference between PPGI and PPGL?

PPGI (Pre-Painted Galvanized Iron) uses a zinc-coated steel base, while PPGL (Pre-Painted Galvalume) uses an aluminum-zinc alloy coating. PPGL offers better corrosion resistance, especially in coastal areas.

Can I get custom colors and designs?

Yes, we offer RAL color matching and custom printing for wood, marble, brick, and other patterns on PPGI/PPGL coils.

What are the standard packaging options?

Our steel coils are packed in seaworthy export packaging with inner plastic film, outer iron sheet, and wooden pallets to prevent moisture and damage during transit.

Do you offer OEM services?

Yes, we support OEM and ODM orders. We can produce under your brand name with custom specifications and packaging.

What is the minimum order quantity (MOQ)?

The standard MOQ is 25 metric tons per size and color. We can discuss smaller trial orders for new clients.
