Round Hole - The Most Popular Perforated Sheet Patten

According to the latest surveys, most perforated sheets are produced with round holes. Why? Round roles are manufactured relatively easier with aesthetic effects. The punching mold can last longer and can be easily manufactured and maintained 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.
