Import Color Coated Steel Coil — Buy in Bulk from Supplier in China

The Color coated steel coil from Shanghai Jinyi International Trading Co., Ltd. is manufactured on galvanized steel substrates with organic polymer coatings applied via continuous roll coating. The base material is typically hot-dip galvanized steel with a zinc coating weight of 60 to 180 g/m², as commonly used in construction applications. The coating system includes a primer, topcoat, and backcoat, with thicknesses ranging from 15 to 30 microns per layer, ensuring durability under outdoor exposure.

The product is available in standard thicknesses of 0.3 mm to 0.8 mm and widths from 900 mm to 1250 mm, consistent with industry norms for architectural and industrial use. Color options include standard RAL codes, though specific shades are not listed in the source data. The coating system provides resistance to chalking, fading, and UV degradation, with typical salt spray resistance exceeding 500 hours per ASTM B117 standards. These properties make it suitable for applications requiring both structural integrity and visual consistency.

This coil is primarily sourced by manufacturers in construction, roofing, and light industrial fabrication, particularly for wall panels, ceiling systems, and cladding. Buyers typically require coils in slit or sheet form, with inner diameters of 508 mm or 610 mm and outer diameters up to 1500 mm. Packaging is standard in wooden pallets with corner protectors and moisture barriers. Trade terms are typically FOB Shanghai or CIF, with MOQs negotiable but commonly starting at 5 metric tons per color and gauge. Buyers should confirm coating adhesion and color consistency via batch testing before shipment.

Shanghai Jinyi International Trading Co., Ltd. operates from Pudong, Shanghai, with a registered address in the Merchants Building. The company is classified as an imported supplier with harbor-tier trust verification, indicating it has passed basic documentation and compliance checks but has no public performance history on response time or order fulfillment. The listing does not indicate production capacity, years in business, or direct manufacturing ownership.

The supplier appears to function as a trading entity sourcing color coated steel coils from third-party mills in China. No factory address, workforce size, or export volume is disclosed. There is no mention of in-house testing labs, quality control certifications beyond general claims, or direct relationships with steel producers. Buyers should treat this as a sourcing intermediary and verify all technical claims directly with the supplier prior to order confirmation.
