Expanded Metal is made from sheets of solid metal that are slit and stretched with each stroke of the upper die, forming a raised diamond pattern. This pattern is called regular or standard. The pattern varies by the gauge and type of material and the size of the diamond.
The sheets can also be flattened by rollers for an optional style by passing them through a cold, roll reducing mill. The lightweight properties and open area percentages of Expanded Metal allow it to be easily formed for a variety of energy saving applications such as light diffusers, screens, grilles and filters. When you add it's quality of strength to this list, you also make it popular for panel security enclosures, guards, fixtures and more.Expanded Metal also can be manufactured in heavy gauges for applications such as walkways, ramps and catwalks of all types. Frequently, the heavier gratings and catwalks are used in industrial plants for flooring and stair treads.
