Metal mesh is an industrial material crafted by transforming solid metal sheets through precision stamping or cold-expanding processes.Stamping (Perforating): A die is used to punch precise, repeating holes (round, square, etc.) into the metal sheet.
Expanding (Cold-Drawing): The sheet is simultaneously slit and stretched, creating a seamless, integrated mesh that expands in width.
A hallmark of the expanding process is its material efficiency. The original sheet is strategically slit and stretched so that its length remains largely unchanged, while its width expands significantly—often 3 to 4 times the original size. This creates a larger, stronger panel with virtually no material waste
