Perforated metal sheet
Perforated Metal SheetA metal sheet is said to be perforated if it has been stamped or punched manually or mechanically using laser-cutting technology or CNC to create various patterns or holes in it of different shapes and sizes. Some of the most common materials that are used to manufacture such sheets are aluminum, galvanized iron, and stainless steel. A Perforated metal sheet is also called a perforated metal screen or plate.
The perforating process is more than a century old that has been practiced manually for a long time before it was mechanized through machines and technological devices. Earlier the process of manually punching holes resulted in time-consuming results that were often inconsistent. This led to the invention of machines that improved the process in terms of time, manpower, effort, efficiency, and consistency in design. Some of such machines include laser perforations, die and punch presses, and rotary pinned perforation rollers.
