CR Coils

CR stands for Cold Rolled Coils, which means they undergo further processing after hot rolling to achieve superior properties.

Production:

  • Made from hot-rolled steel that's further rolled at room temperature through a series of high-precision rollers.
  • This cold rolling process strengthens the material, improves dimensional accuracy, and creates a smoother surface finish.
  • Additional treatments like annealing and pickling can enhance specific properties like ductility and corrosion resistance.

Properties:

  • Smoother and more precise: Compared to their hot-rolled counterparts, CR Coils boast a superior surface finish and tighter dimensional tolerances.
  • Stronger and lighter: Cold rolling increases the metal's tensile strength and yield strength, allowing for thinner gauges while maintaining desired load-bearing capacities.
  • More versatile: Their improved surface finish and formability make CR Coils suitable for a wider range of applications.

CR Sheets

They're the flat, sheet-shaped counterparts of CR Coils, sharing many of the same advantages and applications.

Properties:

  • Superior surface finish: Compared to hot-rolled sheets, CR Sheets offer a smooth, aesthetically pleasing surface, ideal for exposed applications.
  • Dimensional accuracy: They boast tighter tolerances, ensuring precise fitting and minimizing waste during fabrication.
  • Increased strength: Cold rolling enhances their tensile and yield strength, allowing for thinner sheets while maintaining required load-bearing capacity.
  • Excellent formability: They're more malleable and can be easily stamped, bent, or drawn into complex shapes.
  • Good weldability: Their consistent surface promotes clean and reliable welding.

Features:

At Jagdamba Steels, our CR Coils/Sheets boast a myriad of features that make them the preferred choice for a diverse range of applications.
