A major advantage of expanded is that the mesh is formed from a single piece of material so the process is not wasteful and therefore cost effective. The material is cut and stretched while still leaving it attached at the knuckle. This allows it to retain its shape when cut and cannot separate or fray. Often cutting to shape is the only fabrication needed. It has excellent corrosion resistance when suitably coated, and the uncut knuckles support weight and withstand stress better than jointed welds or woven materials. Expanded metal sheet can be supplied in a variety of finishes, thickness, raised or flattened. Flattened is smoother and does not indent soft materials if this is a consideration but is not as strong as the more robust raised mesh. Powder coating in your choice of colour will enhance its aesthetic appearance and add to its corrosion resistance as would plastic coating. expanded metal sheet, expanded sheet, aluminum expanded metal, stainless expanded metal, diamond shape mesh, stretched metal, xpm expanded metal, flattened metal, gothic mesh, expanded metal grating, expanded metal mess, walk way.
