What is Cold Rolling?
Cold rolling is the process whereby steel is treated below its recrystallization temperature which is versus to hot rolled steel to produce uniform, flat steel coils. Not only does this compress the thickness of the material, but it also boosts tolerance, improves tensile strength, and smooths surface finishing by hardening the inner strains of the metal. The cold rolling process results in an estimated 20% improvement in overall steel strength, so it’s easy to see why cold rolling is coming into higher and higher demand among industry professionals, engineering firms, and product designers.

Cold Rolled High-Quality Carbon Structure Steel Strip

Our cold rolled steel coils undergo a thorough picking process on a continuous picking line that removes any and all mill scale from the steel. This produces a clean surface prior to cold rolling so that the end result is a strong and durable material with a high-quality surface.

Today, cold rolled steel is used in products that span the whole of human industry, from metal desks and filing cabinets to motorcycle exhaust pipes, from fan blades and frying pans to computer cabinets and components. No matter what line of business your company specializes in, it is likely that you use cold rolled steel. Sinowell Metal offers the highest quality cold rolled steel coils at the most competitive prices. The professionals at Sinowell Metal have the experience and the expertise necessary to custom design cold rolled steel coils to accommodate your needs.

After the cold rolling process has been completed, we use annealing to make our steel coils extra workable. Annealing involves heating the metal above its recrystallization temperature and then cooling it back down again. This resettles the microstructure of the steel, improves the mechanical properties of the metal, and relieves the internal stresses that build up during cold rolling. The annealing process means that our steel coils are especially customizable and can be easily worked to meet the specifications of the project at hand. This is only the second stage of our three-step process: now that the metal has been made more elastic, we need to toughen it back up again.
Once the metal has been annealed, we put it through a multi-stage tempering process that uses light pressure to flatten the steel so that our premium surface finish can be applied. This ensures that the metal not only looks good, but avoids the stretcher strains that tend to occur during forming and deep drawing.

Cold Rolled Strength Low Alloy Steel Coil

Our tempering process uses precise instrumentation and detailed supervision to achieve just the right elemental balance in each and every steel product we make. We subject all of our products to the same process and the same meticulous quality inspection each time, every time. The end result is a steel coil that you can depend on, one that is strong, malleable, and resistant to wear and tear.
