A CRCA perforated panel is fabricated from Cold Rolled Close Annealed (CRCA) steel sheet, featuring regularly spaced holes to optimize airflow, aesthetics, and weight reduction while maintaining necessary rigidity.

Base Material

  • Type: Cold Rolled Close Annealed (CRCA) steel
  • Thickness: Standard range is 0.35 mm to 3.2 mm; typically, panels are made in 1.0–2.0 mm for industrial and enclosure purposes depending on load and design requirements.
  • Width: Up to 1870 mm for sheets; cut to required panel size.
  • Grade: Conforms to IS 513 standards (grades such as CQ, DQ, DDQ, EDDQ).

Perforation Details

  • Hole Type: Usually round, but custom shapes (square, slotted) available based on application.
  • Hole Diameter: Typical sizes range from 0.4 mm to 6 mm, with spacing (pitch) customized to achieve desired airflow or visual effect.
  • Pattern: Uniform grid, staggered, or custom per design; can be specified in drawings.

Surface Finish & Edge

  • Finish: Dull, bright, or matt, as required for further treatment or visual appearance.
  • Edge: Mill edge or slit edge based on sheet supply.

Applications

  • Electrical and electronic equipment enclosures
  • Machinery guards
  • Decorative architectural cladding
  • Ventilated panels for HVAC and filtration
  • Storage rack panels
