Authentic Steel manufactures high-performance color coated steel coil tailored for diverse appliance, industrial, and architectural sectors. Available in vibrant solid colors, deep matte textures, and exquisite printed patterns (wood grain, brick, marble), our prepainted coils provide exceptional scratch resistance, beautiful surface aesthetics, and smooth processing performance on automatic punch lines.
In modern industrial design, surface aesthetics and long-term durability are critical to product value. Authentic Steel, operating from the bustling commercial shipping hub of Tianjin since 1994, serves as the dedicated export arm of Winroad Group, delivering premium color coated steel coil to manufacturing facilities across 78 countries. Our manufacturing capabilities bridge the gap between heavy industrial protection and delicate decorative elegance, giving our global clients access to custom steel materials that directly streamline their assembly lines.
Our color coated steel coil options can be fully customized across multiple metal substrates depending on your final application. For cost-effective interior partitioning, indoor shelving, or ventilation ducting, we utilize premium cold-rolled steel or light zinc galvanized substrates. For structural roll forming or consumer appliance manufacturing, we implement advanced hot-dip galvanized or galvalume steel cores. Our automated coating lines maintain a thickness range of 0.085mm to 1.4mm, ensuring a flawless surface without pinholes, micro-blisters, or uneven paint streaks across the entire coil length.

A major advantage of sourcing from Authentic Steel is our expansive aesthetic and texture catalog. Beyond standard solid RAL colors, we specialize in high-demand prepainted color design coils and textured matte plates. We can print lifelike wood grains, classic brick patterns, and sleek marble effects directly onto the metal strip, followed by a clear protective top coat. For appliance manufacturers building refrigerator enclosures or air conditioner panels, we apply a clear protective polyethylene film over the top coating (5um to 35um thickness). This film guards the pristine finish against any scratches, abrasions, or scuffs during high-speed automated blanking, stamping, and assembly operations.
Our commitment to absolute quality control is deeply woven into our corporate identity. The technical team at Authentic Steel tests every batch of color coated steel coil using cross-hatch paint adhesion matrices, MEK solvent resistance wipes, and pencil hardness testers to confirm strict scratch resistance. Our strategic proximity to the Port of Tianjin allows us to coordinate fast logistics and secure optimized shipping routes.
