Expanded Metal

Our expanded metal is a very versatile and economical product made from a high-quality sheet of aluminum, carbon steel, galvanized steel or stainless steel that is uniformly slit and stretched, forming diamond-shaped openings in the sheet that allow for the passage of light, air, heat and sound. The expanded metal sheet strands and bonds of the diamonds add strength and rigidity. Because no metal is lost in the expanding process, expanded metal is a cost effective alternative to perforated metal.
