Are you considering the use of perforated metal for your products? Are you having trouble determining which of the various hole types is best for your applications? Slotted hole perforated metal could be your best choice if you’re looking for an elongated hole, as opposed to a round or square shape.
Slotted perforated metal is specifically designed to enable large quantities of materials to pass through without adversely affecting the metal’s strength and overall performance. It’s also extremely flexible — you have the option to choose from a variety of specific shapes that have either square or round hole ends.
Additionally, you can select from various perforated metal slotted hole patterns including side-staggered, end-staggered and straight-line. You can even have a combination of a straight and staggered pattern on the same work piece. In most instances, the longer slot dimensions can be furnished with either the width or the length of the metal sheet. Slotted hole perforated metal is also easy to fabricate
