Commercial Grade Cold Rolled Steel Coils & Sheets

Your Reliable Source for Commercial Quality CRS

Established in 1998, Runfei Steel Group is a premier steel distributor and processing center located in Tianjin. We supply premium commercial grade cold rolled steel (CRS) directly from China’s top-tier mills. Commercial Quality (CQ) cold rolled steel is the backbone of the precision manufacturing industry, offering a superior balance of affordability and aesthetic quality. Backed by our 30,000-ton indoor warehouse, we ensure that our cold rolled coils and sheets are fully protected from moisture and environmental elements, ready for immediate dispatch.

Understanding Commercial Grade Cold Rolled Steel

Commercial grade cold rolled steel is processed at room temperature and subsequently annealed to restore its ductility. Unlike Drawing Quality (DQ) steel, which is formulated for severe stretching, Commercial Quality (CQ) is specifically designed for flat applications, moderate bending, and mild forming. Because of the cold reduction process, it boasts highly accurate thickness tolerances and a smooth, unscaled surface that is perfectly primed for painting, powder coating, and enameling.

Core Applications & Industries

The flawless surface and precise dimensions of our commercial grade cold rolled steel make it the material of choice for highly visible applications:

• Metal Furniture & Cabinetry: The primary material for producing file cabinets, lockers, shelving units, and architectural fixtures.

• Home Appliances: Ideal for manufacturing the sleek exterior panels of washing machines, refrigerators, and HVAC units.

• General Fabrication & Enclosures: Used extensively for electrical control boxes, computer casings, and precision brackets.

• Precision Tubing: Serves as the reliable base material for producing high-quality welded steel tubes for furniture and automotive parts.

Frequently Asked Questions (FAQ)

Q: What is the main difference between Commercial Quality (CQ) and Drawing Quality (DQ) cold rolled steel?
A: Commercial Quality (CQ) steel is highly cost-effective and suitable for standard fabrication, light bending, and welding. Drawing Quality (DQ) steel undergoes stricter metallurgical control to allow for deep, complex stretching without tearing, making it ideal for intricate automotive panels or sinks.

Q: Can you process commercial grade cold rolled coils to our exact width requirements?
A: Absolutely. At our advanced Tianjin Hangu facility, which features a 300,000-ton annual processing capacity, we provide comprehensive coil slitting and precision cut-to-length services. We can deliver the exact dimensions your automated production lines require.

Q: How is the cold rolled steel protected against rust during international transport?
A: Rust prevention is our top priority for cold rolled steel. We apply a protective layer of anti-rust oil to the steel surface. Furthermore, we use rigorous seaworthy packaging—wrapping the coils in multi-layer moisture-resistant kraft paper, adding steel edge protectors, and securely strapping them to guarantee they arrive in pristine condition.
