Selecting the Best Perforated Pattern and Hole Shape

February 25, 2016

Whether for function or appearance, the right perforated pattern matters. What options are available, and how do you know what’s right for your application?

What Type of Hole is Best for You?

First, it helps to have a basic understanding of the types of holes commonly used in perforated metal patterns. They fall into four categories: round, square, slot, and ornamental or decorative.

Rounded holes are among the most common because they are relatively simple to do and can be the more cost-efficient option. In terms of applications, rounded holes are often one of the most universal and can be used in applications like air conditioning and heating. Round perforated panels are also commonly used as decorative additions to existing structures.

The next most common is square. The cost to produce square holes is higher than round because the corners put added strain on the corners of the punches. However, the benefits of square holes are impressive, including a more transparent view through the panel without sacrificing strength to resist impact

Next, there are slot holes, which are essentially elongated holes with either rounded or square ends. Cost-wise, they can be similar to square perforated holes. This option is most commonly used for industrial applications, including the sorting of materials like grains.

Lastly, there are the patterns in the ornamental or decorative category. These patterns range from simple designs like hexagon, diamond, and cloverleaf shapes to very complex like Lincane, Saratoga, and Union Jack. These patterns are frequently use in interior design for screening and decorative applications.

What are the Advantages of Certain Patterns?

You also have options when it comes to perforated design. The most common include staggered, straight and ornamental.

Staggered means the holes are positioned so that they align diagonally or on an angle. The advantage of this can be a unique, attractive appearance. Staggered is typically limited to round holes.

Straight-line holes are exactly what you would think. The rows repeat in identical numbers of holes following the same alignment. While decorative, this design is also good for functionality.

Some customers prefer an entirely customized look, or at least one that does not conform to traditional. Those include specific ornamental patterns like spirals or actual objects. These patterns are largely for decorative purposes only.
