Square Holes

Perforated Square hole on building Square Perforations

If you are in the market for perforated metal sheets, your choice essentially comes down to three basic hole types: round, square and slotted. While round hole sheets are the most commonly purchased, square hole perforated metal offers a number of important advantages for specific industries and applications. Marco Specialty Steel is a proud perforated square hole metal supplier that can provide the right solution for your company and back it with a quarter-century of steel industry expertise.

Consider the Many Benefits of Square Hole Perforated Metal

For many, perforated metal square hole patterns are more visually appealing than round holes, a key consideration when the aesthetics of the product are of primary importance. Additionally, square hole perforated metal provides a larger open area, making it easier for bulkier materials — or, in the case of audio equipment, sound — to pass through.

Another key benefit of square hole metal is its high strength-to-weight ratio. The sheets allow heavy material filtration without sacrificing strength and performance.

Perforated Metal Square Hole Patterns

You can typically purchase square hole perforated metal in sheets or coils and in either a staggered or straight-line hole pattern. When choosing a straight pattern, the row of holes usually runs parallel to the long dimension of the sheet, while a staggered square hole pattern features a short dimension direction.

Marco Specialty Steel has the in-house fabrication capabilities to provide a custom perforated square hole pattern for unique or specialty applications, if required.

Examples include audio speaker grilles, machine guards and virtually any screening application that requires large open areas and a superior strength-to-weight ratio.
