According to the latest surveys, most perforated sheets are produced with round holes. Why? Round roles are manufactured relatively easier with aesthetic effects. The circular die for punching sheet can last longer and easy to be manufactured which makes the round hole perforated sheet cheaper than any other perforated sheet with other hole patterns. Therefore, round hole pattern becomes the most popular shape.

Round hole perforated sheet offers the widest options of hole sizes, gauges, materials and sheet size for all types of applications. For example:

a perforated steel sheet with 60° staggered round holes
