Authentic Steel is the export department of Winroad Group and a professional manufacturer and exporter of high-precision cold rolled steel coils (CRC). From our Tianjin production hub, we supply automotive stampers, home appliance manufacturers, electrical enclosure builders, and steel re-rollers in 78+ countries. We provide mill-direct pricing, custom processing, and rapid export dispatch through Tianjin Port. Our CRC series can be supplied to international specifications on request.
Commercial & Deep Drawing CRC: Standard grades include SPCC-SD, DC01, Full Hard, and Black Annealed according to our brochure. Other deep drawing grades such as SPCD, SPCE, DC02, DC03, DC04, DC06, ST12, ST13, and ST14 are available on request. Annealed coils offer good ductility, formability, and surface consistency for automotive panels, home appliance casings, radiators, and precision tubing.
Full Hard Cold Rolled Coils: Unannealed coils supplied directly after cold reduction, featuring high hardness and high yield strength. They are suitable as a cost-effective substrate for continuous hot-dip galvanizing and galvalume lines, as well as for high-tensile hardware and general manufacturing.
Black Annealed CRC: Black annealed surface is available according to our brochure. It is suitable for applications requiring a dark, annealed surface and good formability.
Surface Finishes & Skin-Passed Coils: Bright, dull, matte, and skin-passed finishes are available on request. Skin-pass rolling can help improve surface flatness and forming performance for painting, coating, and laser cutting.

Every production batch undergoes laboratory inspection, including tensile strength, yield strength, elongation, hardness, and surface checks. A Mill Test Certificate (MTC) can be supplied on request, and third-party inspection is available on request.
To reduce transit rust, scratch damage, and edge deformation during ocean freight, our coils use multi-layer export packaging: anti-rust VCI paper, plastic moisture barriers, galvanized steel outer casing, metallic corner guards, and heavy radial and circumferential steel banding secured on heat-treated wooden skids. This packaging is suitable for long-distance container shipment and safe unloading.
