Functional and attractive, perforated metal is seen virtually everywhere in today's world. Depending on the size and shape of the perforated openings-and the gauge-it can be many things. From a behind-the-scenes workhorse at screening and filtering a variety of solids, to a visually appealing diffuser of light and/or air for many architectural applications, perforated sheet metal is the solution that can even perform artistically as a display. Often it is advantageously employed in place of metal sheeting to lighten the weight of some products, without sacrificing too much strength.
