This ASTM prepainted steel coil from Qingdao Qinyuansteel.Co., Ltd. is a color-coated steel product with a zinc coating range of Z60 to Z180 and a thickness between 0.16 mm and 1.2 mm. The coil is supplied with inner diameters of 508 mm or 610 mm, designed for processing flexibility in downstream applications. The zinc coating provides corrosion resistance, extending the material’s service life in outdoor and industrial environments.
The base substrate is cold-rolled steel, prepainted with a polyester or silicon-modified polyester topcoat for aesthetic and protective performance. Standard industry practice for prepainted coils includes a reverse-side coating of 5 to 10 microns for additional barrier protection. The product is finished with a typical coil weight of 3 to 6 metric tons, though this supplier’s exact packaging weight is not specified.
This material is sourced by manufacturers in construction for roofing and cladding, by appliance makers for exterior panels, and by automotive suppliers for trim components. Buyers typically import in full container loads under FOB or CIF terms, with lead times and MOQs to be confirmed directly with Qingdao Qinyuansteel.Co., Ltd. The product meets ISO 9001:2008 certification as stated by the supplier, ensuring consistent quality control in production.

Before placing an order with Qingdao Qinyuansteel.Co., Ltd., verify the exact coil dimensions, including thickness, width, and inner diameter, to ensure compatibility with your production line. Confirm the zinc coating weight and topcoat type, as these directly impact durability and performance in your application. Request third-party inspection reports for coating adhesion, color consistency, and corrosion resistance if the supplier’s internal testing is insufficient.
Logistics details such as lead time, Incoterms (FOB or CIF), and payment terms should be negotiated upfront. Prepainted coils are typically shipped in 20-foot or 40-foot containers, with each coil secured to prevent movement. Clarify whether the supplier provides export packing, including edge protection and moisture barriers, to avoid transit damage. Port of loading and discharge should also be agreed to align with your shipping schedule.
Quality checks should include visual inspection for coating defects, thickness measurements at multiple points, and adhesion tests using cross-hatch or T-bend methods. For critical applications, consider independent lab testing for salt spray resistance and colorfastness. Ensure the supplier provides a material test certificate (MTC) and ISO 9001:2008 compliance documentation. Document all agreements in the purchase contract to address potential discrepancies upon delivery.
