How to specify prepainted and galvalume coated steel coil.
Practical Standard Review
Color coated steel RFQs should confirm base metal, metallic coating, primer, top paint, back paint, color code, gloss, film thickness, application environment, packing, and warranty expectation.
Himount Steel reviews the ordered standard, grade, product form, dimension tolerance, inspection level, packing method, and shipment route before confirming price and lead time. Final supply always follows the buyer specification and accepted mill test certificate.
Key Ordering Points
| Main comparison | Color coated steel RFQs should confirm base metal, metallic coating, primer, top paint, back paint, color code, gloss, film thickness, application environment, packing, and warranty expectation. |
|---|---|
| Confirm in RFQ | PPGI or PPGL, base steel, zinc or Al-Zn coating, paint type, color, gloss, T-bend, and film thickness |
| Risk to avoid | Color name is not enough; use RAL or agreed sample and confirm paint system. |
| Documentation | Confirm MTC type, heat number traceability, inspection record, and any buyer approval wording. |
| Next step | Send the project specification or previous PO so Himount Steel can check the supply route. |
Buyer Checks Before Quotation
- Use the project specification as the authority when grade names look similar.
- Confirm product form, size, tolerance, delivery condition, and inspection plan together.
- Ask for comparable references only as RFQ aids, not automatic substitutions.
- Review certificate wording before shipment if the project has strict acceptance rules.
