Types of expanded metal: Flattened Expanded Metal is manufactured by passing the standard expanded sheet through a cold-roll reducing mill. Standard Expanded Metal offers high rigidity in a variety of sizes and weights. The angles of the diamond strands allow maximum air circulation and distribute stress on the metal to supporting frames. Expanded Metal Grating is fabricated from low carbon steel plates and is ideal for use wherever a strong, durable, lightweight surface is needed.
