Frequently Asked Questions

For regular color coated coil, the usual starting point is 5–10 tons per color and specification. That said, we are happy to support first-time buyers with smaller trial orders or mixed-container loading across several colors or sizes. Send us your spec and we will confirm the exact MOQ for your case.

Standard lead time is 7 days after your deposit and final color confirmation, depending on quantity and season. Custom-matched colors add a few days for the first approval cycle. We keep some popular RAL colors in regular production, which can shorten the wait.

PPGI uses a hot-dip galvanized (zinc) substrate, while PPGL uses a Galvalume (aluminum-zinc) substrate. PPGL resists corrosion better and suits coastal or humid environments; PPGI is usually the more economical choice for indoor use. See our PPGI vs PPGL comparison for the full picture.
