One of the best things about using perforated metal is that it offers such a wide range of flexible, versatile options. This includes the ability to choose from various perforation patterns to meet your project requirements. Among the three standard perforated metal hole patterns — round, square and slotted — round is the most popular and most frequently selected option. Marco Specialty Steel offers high-quality round hole metal products that will deliver results and exceed your expectations.

What Are the Benefits of Round Hole Metal Products?

Why are perforated metal round hole patterns chosen more often than square or slotted holes? Because they offer the best combination of ease of manufacturing, low maintenance and affordability. You also get the broadest selection of gauges, diameters, sheet size options and material choices, making it easier to get the ideal product for your needs. Round hole perforated metal also lasts longer than the other types, making it the most cost-effective alternative in the long run.

You Can Use Round Hole Perforated Metal for So Many Different Things

Round hole metal products can be used for numerous functional and decorative purposes, including:

  • Separating ore or rock in mining applications
  • Security in windows, gates and doors
  • Air filtration for electronic equipment

  • Noise reduction in large engines
