What is the difference in the manufacturing process between expanded metal sheets and perforated metal sheets?

Expanded metal sheets are manufactured by creating multiple slits in the sheet and then stretched to expand. These slits, when expanded, create a beautiful diamond pattern in a chain-like series throughout the sheet. This pattern strengthens the structure the sheet, making it highly durable. Also, this process does not create any waste and is, therefore, cost-effective.

On the other hand, perforated metal sheets are manufactured by punching or stamping holes into the metal. These stampings can come in different shapes and designs as desired. However, the size of the holes determines the amount of scrap that is removed from the sheet. The cost of production increases with the volume of scrap produced.
