Perforated Metal Sheet, also known as perforated sheet, perforated plate, or perforated screen, is sheet metal that has been manually or mechanically stamped or punched using CNC technology or, in some cases, laser cutting to create different holes sizes, shapes and patterns. Materials used to manufacture perforated steel sheets include stainless steel, cold-rolled steel, galvanized steel, brass, aluminum, tinplate, copper, Monel, Inconel, titanium, plastic, and more.

The process of perforating metal sheets has been practiced for over 150 years. In the late 19th century, metal screens were used as an efficient means of separating coal. The first perforators were laborers who would manually punch individual holes into the metal sheet. This proved to be an inefficient and inconsistent method that led to new techniques, such as perforating the metal with a series of needles to create the desired hole pattern.

Materials:

Perforated Metal sheets are made of high-quality metal plates: Aluminium plate, copper plate, mild steel plate, stainless steel plate and so on.
