What's Expanded Metal?

Expanded metal is a sheet of metal fabricated with an everyday pattern of diamond-shaped openings.

It presents one-piece development that won’t unravel under normal circumstances, and will hold its form for a lot of years. The strands and bonds of the diamond-shaped trusses add power and rigidity.

It's commonly utilized in a wide range of applications, comparable to:
