We only sell high quality expanded metal. Expanded metal is a type of sheet metal which has been cut and stretched to form a regular pattern (often diamond-shaped) of metal mesh-like material, allowing the metal to stay in one piece. High strength: Expanded metals support weight and withstand stress better than woven metals or jointed welds. Low weight: Expanded metals are lighter than traditional metal sheets. Allows circulation: Expanded metal allows air and light to move freely. It can be used in many different industries such as building and construction, architecture, car styling, agriculture and many more.
