Round Holes  

ROUND HOLES ranging from under 0.6mm to over 75mm account for 80% of the production of the perforating industry. Round holes can be produced with greater efficiency and less expenses than any other hole shape. The dies and punches to make round holes are the most cost efficient to build & maintain. Round holes are the most versatile in their application, providing a wide range of open area and handsome appearance.

60 DEGREE STAGGERED ROUND HOLE PATTERN is the most popular hole arrangement because of its inherent strength and the wide range of open areas it provides.

45 DEGREE STAGGERED ROUND HOLE PATTERN is stronger than straight row patterns it is not as strong as 60 degree staggered arrangement, nor is it as versatile in providing compact hole spacing & high open areas as the 60 degree arrangemen.
