Expanded Metal is a versatile and economical product. Made from a sheet of metal uniformly slit and stretched, forming diamond-shaped openings in the sheet - Expanded is a 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 Metal comes in a standard (raised) or flattened diamond pattern in a variety of gauges, opening sizes, materials and sheet sizes.

Expanded Metal is typically used for screening, ventilating or security as a guard. The openings permit passage of light, air, heat and sound, and sheet is lightweight and easy to fabricate and form. Decorative patterns have the same properties and are used aesthetically. Decorative patterns may be found in applications like retail shelving, signage, partitions, ceiling tiles, and more.
