Expanded sheet metal is a versatile and economical product. As the name suggests, expanded sheet is made from a single sheet of metal that has been uniformly slit and then stretched (expanded) to form diamond-shaped openings in the meet.
Expanded sheet offers one-piece construction that won’t unravel and, under normal circumstances, and will hold its shape for many years. The strands and bonds of the diamond-shaped trusses add strength and rigidity. Expanded sheet metal is available in standard (raised) or flattened diamond patterns, in a variety of gauges, opening sizes, and sheet sizes.

Expanded Sheet Materials

Expanded Sheet Profiles

  • Standard Expanded Sheet: A finished product as it comes off the press after being die cut and expanded. Often referred to as raised expanded sheet.
  • Flattened Expanded Sheet: A standard expanded sheet that is then cold rolled, leaving a flat, smooth surface. Flattened expanded sheet is about 5% lighter than standard expanded sheet.
  • Expanded Metal Grating: A heavy duty expanded sheet manufactured from carbon steel sheet or plate. Expanded metal grating has no joints or welds, as each sheet is a single piece of sturdy steel. Ideal for catwalk and platform applications.
