Commonly Perforated Carbon Steel Types
Commercial Steel (HR, CR, GALV) A low cost steel that has good drawing, forming, and welding qualities, moderate strength, but is subject to strains, fluting, and breaks due to aging. To reduce the affects caused by aging, Drawing Steel is recommended.

Drawing Steel (HR, CR)
A steel with a greater degree of ductility and uniformity of properties than Commercial Steel providing improved performance during manufacturing. This type is recommended for use when stretcher strains or fluting during fabrication are objectionable and/or consistency of performance is important.

Perforation pattern usually is round holes, there is straight line holes and staggered line holes, different open area need different diameter center distance. 15%-33% open area is common configuration. Formulas for your reference

A: 60° perforation pattern or staggered pattern: hole diameter * hole diameter*90.69% / hole center distance * hole center distance

B: 180° perforation pattern or straight pattern: hole diameter * hole diameter * 78.5% / horizontal diameter center distance * vertical diameter center distance

C: Other special cases as follows
