Precision Cold Rolled Steel Coils & Sheets

Your Trusted Supplier for Cold Rolled Steel

As a premier steel distribution and processing hub established in 1998, Runfei Steel Group delivers high-quality cold rolled steel (CRS) to global manufacturers. Cold rolled steel is essentially hot rolled steel that has undergone further processing at room temperature, followed by annealing and temper rolling. This meticulous process yields steel with exceptionally tight thickness tolerances, enhanced strength, and a smooth, pristine surface finish. Backed by our 30,000-ton indoor warehouse in Tianjin, we ensure that our cold rolled coils and sheets are protected from the elements and ready for prompt dispatch.

Key Advantages of Cold Rolled Steel

When precision and aesthetics are critical to your manufacturing process, our cold rolled steel provides unparalleled benefits:

• Superior Surface Finish: The smooth, unscaled surface is perfectly primed for painting, coating, and enameling without the need for extensive pre-treatment.

• Tighter Dimensional Tolerances: Advanced cold rolling technology ensures highly consistent thickness and width, which is vital for automated stamping and forming lines.

• Enhanced Mechanical Properties: The cold working process increases the yield strength and hardness of the steel compared to its hot rolled counterparts.

Core Applications & Industries

Because of its excellent formability and flawless appearance, our cold rolled steel is heavily utilized across high-end manufacturing sectors:

• Home Appliances: The primary material for manufacturing exterior panels for refrigerators, washing machines, and microwave ovens.

• Automotive Manufacturing: Used extensively for car body panels, precision chassis components, and internal structural parts.

• Metal Furniture & Cabinetry: Ideal for producing file cabinets, lockers, and architectural fixtures where a sleek finish is required.

• Precision Tubing: Serves as the base material for high-quality, thin-walled welded steel tubes.

Frequently Asked Questions (FAQ)

Q: Can you process cold rolled steel coils to our specific dimensions?
A: Yes. At our Tianjin Hangu processing center, which boasts an annual capacity of 300,000 tons, we offer comprehensive coil slitting, edge trimming, and precision cut-to-length services. We can supply materials precisely tailored to your production line’s exact specifications.

Q: How do you protect cold rolled steel from rusting during sea freight?
A: Unlike hot rolled steel, cold rolled steel lacks a protective mill scale and is highly susceptible to rust. We apply a light layer of rust-preventative oil prior to shipment. Furthermore, we utilize strict 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 perfect condition.

Q: What is the difference in cost between hot rolled and cold rolled steel?
A: Cold rolled steel generally commands a higher price than hot rolled steel due to the extensive additional processing required (cold rolling, annealing, and surface finishing). However, the investment is justified for projects requiring precise dimensions and a paint-ready surface.
