What Is Prepainted Steel Coil?

Prepainted steel coil—commonly referred to as color-coated steel coil—is cold-rolled or galvanized steel substrate that undergoes a continuous coil coating process. The base metal receives chemical pretreatment, a primer coat of 5–8 μm, and a top finish coat of 15–25 μm (typically polyester, SMP, HDP, or PVDF resin), resulting in a product ready for immediate roll forming, stamping, or profiling without additional on-site painting.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Standard RAL colors carry an MOQ of 25 MT per color and thickness combination. For custom or metallic finishes, the minimum starts at 30 MT to ensure optimal coating line efficiency.

Prepainted steel coil wholesale

Do you provide material test certificates?

Yes. Every shipment includes a mill test certificate (MTC) per EN 10204 Type 3.1, covering substrate mechanical properties, zinc coating mass, paint film thickness, adhesion (cross-cut test per ASTM D3359), and T-bend flexibility results.

What is the typical delivery time?

Production lead time ranges from 15 to 25 working days after order confirmation, depending on color complexity and quantity. Stock RAL colors such as RAL 9002 and RAL 5015 ship within 7–10 days.

Acceptable PPGI Quality with Initial Documentation Delay Resolved

Ordered 30 MT of PE-coated PPGI, 0.5mm thickness, 1,000mm width, RAL 9003 white for light industrial wall panel production in Ontario. Coating quality itself was acceptable—film thickness at 17–18 μm and cross-cut adhesion at Grade 1, within tolerance for our application. The issue was that the EN 10204 Type 3.1 mill test certificate was not included with the initial shipping documents, which held up our customs broker for 4 days. After escalating to the technical sales contact, the certified MTC was issued and transmitted within 24 hours, resolving the clearance. Production lead time of 17 working days was as quoted. Pricing was competitive. Supplier acknowledged the documentation oversight and confirmed a checklist update for future orders. Willing to reorder given the responsive follow-up, but documentation process needs to be more reliable upfront.

Perfect Color Consistency Across 120 MT Multi-Color PPGI Order

As a regional distributor serving Southeast Asian fabricators, we placed a consolidated order of 120 MT across six RAL colors—all PE coating, 0.35mm to 0.7mm thickness, 600mm to 1,250mm widths. Managing multi-color batch consistency is always our main concern. Every coil batch measured ΔE ≤ 1.3 against approved color standards, which our customers in Malaysia and Vietnam confirmed when processing. In-house slitting to 300mm and 500mm strips was executed cleanly with tight width tolerance. All six colors shipped in a single 40-foot container with export-standard seaworthy packaging; no moisture damage reported. This is our fourth consolidated order over 18 months. The 25 MT MOQ per color makes it practical for us to offer variety to smaller fabricators without excess inventory risk.

Reliable HDP Prepainted Coils for Agricultural Building Kits

Sourced 40 MT of HDP-coated PPGI, Z200 galvanized substrate, 0.55mm thickness, 1,150mm width, RAL 6020 green for prefabricated agricultural shed kits sold across Queensland and New South Wales. Pencil hardness confirmed at 3H as specified, which matters for our roll-forming process. BV inspection at loading was arranged smoothly—inspection report received before vessel departure. CIF pricing to Brisbane was about 4% above our initial budget estimate, though the MTC documentation quality and coating consistency justified the difference when we factored in reduced rejection risk. Stock RAL color availability meant we received partial shipment within 9 days for an urgent order top-up. Solid supplier for ongoing shed kit procurement.
