Expanded metal is formed from a metal material which is then cut and stretched while still leaving it attached to the sheet at the knuckle. The manufacturing process enables the metal to retain its shape when it is cut. The uncut knuckler support weight and can withstand stress better than some welded wire mesh or woven wire materials. It can be supplied in a variety of finishes, thickness, raised or flattened. Flattening creates a smoother surface but is not as strong as the more robust raised metal mesh often used for walkways.
Available in SUS 304, SUS 316, Mild Steel, Galvanised etc.
