Hot rolled flat expanded metal sheet, also referred to as grating or mesh, is an excellent candidate for most processing techniques. Made from lightweight carbon steel, this material features smooth, flattened diamond-shaped openings along the surface. Common applications include walkways, screens, grills, and safety guards. ASTM F1267 Type II Class 3 is the standard specification for expanded metal steel.
