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.
Forming Steel (GALV)
A steel with lower strength and higher elongation than Commercial
Steel. Recommended when stresses from forming either crack or
weaken Commercial Steel
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
