Cold Rolled Steel Coil
Cold-rolled steel refers to steel that is processed by rolling at a temperature below the steel's recrystallization temperature. It is typically produced from hot-rolled steel coils as raw material, processed at room temperature through multiple rolling passes, annealing, and leveling processes.
Cold rolled steel is a widely utilized material known for its superior mechanical properties and aesthetic finish. Within this category, the DC06 Supreme Extra Deep Drawn SEDDQ (Super-Electric Deep Drawn Quality) has garnered attention for its exceptional performance in demanding applications. This product is engineered for superior formability, making it indispensable in industries requiring high-quality deep-drawn components.
