CR Slit Coils

A CR Slit Coil is a metal product that starts as a large Cold Rolled (CR) coil and is then precisely cut, or "slit," into narrower coils (often called strips or mults) of a specific, custom width.

Here is a detailed breakdown of its description, process, and applications.

1. Description and Characteristics

CR Slit Coils are defined by the material and the manufacturing step that creates them:

• CR (Cold Rolled) Material: This means the steel has been rolled at or near room temperature, resulting in a product with:

  • Superior Surface Finish: It is smooth, clean, and often bright.

  • High Dimensional Accuracy: It has tight tolerances for thickness and width.

  • Enhanced Strength and Hardness: The cold-rolling process refines the materials structure, improving its mechanical properties.

• Slit Coil (Strip): This indicates that a wider, original coil (often called a "master" or "mother" coil) has been processed on a slitting line.

  • Process: Circular rotary knives cut the wide coil lengthwise into multiple narrow strips.

  • Result: These strips are then re-wound into smaller, ready-to-use coils that meet exact width specifications.
