How do they make expanded metal sheets.

Expanded metal is a type of sheet metal which has been cut and stretched to form a regular pattern often diamond shaped of metal mesh like material. The expanding machine is fitted with a knife which determines pattern for the mesh. Flattened expanded metal sheet with smooth and safe surface is widely used as storage basket safety gate furniture and shelves in our daily life. Because no metal is lost in the expanding process expanded metal is cost effective and saves energy by conserving material and allowing the fabrication to go further and do more.

Expanded metal is produced by an expanding machine which turns solid metal sheets and coils into an expanded metal mesh. Expanded metal is stronger than an. The sheets coils are fed into the expanding machine and the precision die cuts and stretches the metal in a single operation. Expanded metal is manufactured through slitting and stretching by a set of die with upper blade and lower blade while the diamonds may vary and this drawing just shows how a solid metal sheet becomes expanded metal without waste.

As the metal is fed through the expanding machine it is cut and stretched simultaneously using a pressured slitting and stretching process. It is commonly used for fences and grates and as metallic lath to support plaster or stucco description. To produce expanded metal a sheet or plate is simultaneously slit and stretched.
