Perforated Metal Filter and Strainer Standards

Our custom perforated metal filters and strainers are always manufactured to your specifications, with a wide range of materials, hole sizes and perforation patterns available. They can be constructed or reinforced with perforated metal. Perforated metal strainers and filters are resistant to bending and crimping, making them an ideal choice over wire mesh filters in demanding applications that call for rigidity and durability. Varying perforation patterns and percent open area also allow engineers to achieve desired flow rates and size sorting.

Material Choices

  • Aluminum

  • Brass

  • Carbon Steel

  • Monel

  • Stainless Steel 304

  • Stainless Steel 316

Perforation Patterns

  • Round Perforations Staggered

  • Square Perforations Staggered

  • Round Perforations Straight Line
  • Square Perforations Straight Line

  • Slots Side Staggered

  • Slots End Staggered

Expanded Metal Filter and Strainer Standards

Yankee Wire Cloth Products can make custom metal filters and strainers constructed or reinforced with expanded metal. Our custom expanded metal filters and strainers are always manufactured to your specifications.

Expanded metal can serve as a single filtration element or as a secondary supporting layer to protect a filter against crimping or bending. Varying patterns with different percentages of the open area allows engineers to achieve desired flow rates and size sorting. The photos below show our standard open areas. Additional custom sizes are available upon request.

  • Carbon Steel

  • Galvanized Steel

  • Stainless Steel 304

  • Stainless Steel 316
