Cold rolled coil is produced by reprocessing hot rolled steel sheets at room temperature. This process makes the surface of the steel smoother, more refined, and precise. Due to its thin and smooth structure, it is preferred in the automotive, white goods, electronics, and precision manufacturing sectors. Cold rolled coils stand out for their high durability, excellent surface quality, and superior formability.
Black Annealed Cold Rolled Steel Coil undergoes professional heat treatment. This recrystallizing process eliminates work hardening from the cold-rolling stage and restores plasticity to achieve specific physical and chemical properties. The flow includes preliminary, intermediate, and finish annealing. To ensure a strip with no oxidation or decarburization, bright annealing in a protective atmosphere is utilized.
Our CR Coils are available in widths up to 1250mm and thicknesses ranging from 0.4mm to 2mm. We also offer CR Sheets (cut-to-length) with lengths up to 6 meters. Available finishes include Bright Annealed (BA), 2B, and No.4, featuring customizable slitting and edge options to meet diverse industrial needs.
