Standard Expanded Metal Sheet

Standard Expanded Metal is manufactured of coil material. This is a material with perforations (diamond mesh) in the surface. They are formed by offset cuts while simultaneously being stretched.

This metal mesh sheet is uniformly slit and stretched, forming diamond-shaped openings in the sheet that allow for the passage of light, air, heat, and sound. The strands and bonds of the diamonds in the expanded metal sheet add strength and rigidity. Since no metal is lost in the expanding process, expanded metal is a cost-effective alternative to perforated metal.
