Round Hole Perforated Sheet in Straight or Staggered Pattern
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.
We specializes in manufacturing round hole perforated sheets in various high quality materials including steel ( mild steel or carbon steel, no painting, galvanized or PVC coated), stainless steel, aluminum, copper and brass or other materials as your request.
