SQUARE HOLES are principally used for grills and machine guards offering a maximum of open area to permit good visibility and through-put while providing the necessary protection or decorative cover. Square holes are weaker than the round patterns. The sharp corners on the square hole tooling makes it more subject to wear and vulnerable to the stresses of the punching process, increasing tooling costs and reducing production rates. Square hole patterns are generally more expensive than the equivalent round.

Perforated sheets with Square Holes can be supplied with straight & staggered hole arrangements for your application. The most common and widest used type among them is the straight one.
