Slotted Stainless Steel Sheet

Perforated stainless steel is a type of sheet metal defined by the presence of a pattern of holes. A machine punches or stamps the metal sheet to obtain the desired hole pattern. This is also referred to as perforated plates, perforated sheets, or perforated screens. Stainless steel, cold-rolled steel, and aluminum are the most common types of metals used in perforating.

First developed 150 years ago, perforated steel sheets were used in the mining industry as a means to filter coal. At that time, the means of perforation were through laborers manually punching the patterns of individual holes into the steel sheet. Nowadays the process is much more efficient as a machine simultaneously punches any number of patterns onto the steel sheet through an array of punching needles.
