Perforation perfection: choosing perforated metal patterns

Perforated metal panels are an attractive addition to any building or development. With an extensive choice of hole styles, sizes and materials – from steel to aluminium, brass and copper – engineers, architects and designers use perforated metal sheets for decorative and functional facades, filters, feature walls, screens and panels. But there’s much more to perforated metal than just architectural appearance. Pick the right pattern and you can control environmental effects including light, airflow, heat and sound. But which perforation is perfect for your project?

Perforated performance: What to consider

What special requirements do the perforated panels need to meet? These will dictate the pattern, pitch and material of the finished fabrication:

Strength: Will the panels be used in stress conditions? Strength varies depending on the metal material, thickness and pattern. We can advise on the strongest combination for your application.

Hole size, styles and pitch: Different perforation patterns impact not just the strength of the panel but how well it’s suited to the intended job. The size, shape and distribution of the holes all affect efficiency.

Arrow Metal’s specialised tooling process, extensive tool range and state-of-the-art punching machines can be configured to offer thousands of different panel patterns, from standard shapes and sizes to unique bespoke decorative and architectural designs. Many popular shapes and sizes are ready-to-go in stock, with others manufactured to order:

  • Shapes: From round and rectangular to square, radiused square, slotted and hexagonal, our standard profile in-stock and made-to-order perforated metal panel range offers almost 60 different combinations suited to most decorative and functional uses.
  • Sizes: From the smallest round perforations of 1.6mm right up to 70mm holes, we can fabricate any size to suit your project.
  • Pitch: Standard pitch includes staggered, diagonal or straight, or we can custom create any arrangement to make the most of your bespoke tooled design.
