Below is a list of Expanded Metal Screens manufacturers from Rancho Cucamonga, California. Expanded metal screens consist of a surface of light gauge sheet metal that has been slit and stretched to create a pattern of uniform small openings. Also known as micro-mesh, screens are common in industrial, commercial and residential environments. Expanded metal meshes such as these vary considerably from extremely fine meshes used as filters to industrial strength screens used as machine guards and material enclosures.
