Wire Cloth Products offers custom metal filters and strainers that are constructed or reinforced with expanded metal.  Expanded metal can be used as a single filtration element or as a secondary supporting layer to protect a filter against crimping or bending.  Varying hole patterns and percent open area also allows engineers to achieve desired flow rates and size sorting.  See the charts below for a variety of standard open areas. Additional custom sizes may be available upon request.  Our custom expanded metal filters and strainers are always manufactured to your specifications, with a wide range of materials, hole sizes, and perforation patterns available.
