Perforated Metal Sheets

Graepels have extensive experience within the Metal Perforation industry in the UK & Ireland. Graepels perforate Metal Sheets in a range of shapes, materials and patterns. This includes standard perforations, bespoke and decorative perforated patterns.

Perforated Metal Sheets have a variety of Architectural, Industrial and Commercial Applications. For instance, Perforated Sheets are an excellent choice for windbreakers, anti-slip flooring & steps, filtration, cladding, ventilation, decorative finishes or noise reduction.

What are perforated metal sheets?

Perforated metal is a manufacturing process where the manufacturer uses CNC technology to punch/pierce a solid flat sheet of metal creating holes (also known as perforations). These perforations/ holes can be a range of different hole sizes and shapes from round to square, hexagonal, slotted and diamond. The perforations are aligned in patterns, pitches and shapes. Perforated Metal sheets are available in a range of material types and thickness. Common perforated metal sheets include; stainless steel, mild steel, aluminum and corten.

For bespoke or unique patterns and designs visit our Picture-Perf Products page or Decorative Metal Sheets page.

Technical Capabilities of Perforated Metal

  • Perforation size: 1mm-154mm (additional Perforation sizes are available on request)
  • Sheet Thickness: Popular thickness: 0.75mm – 12mm. Graepels can perforate up to 25mm thick on special request/order
  • Sheet sizes: Standard sizes include 2mx1m, 2.5mx1.25m and 3mx1.5m. Sheets 4mx2m are perforated on our larger machines. Longer lengths up to 6m perforated by special request.
  • Percentage open area: All open areas are physically possible but standard tooling tends to be between 20% and 60%

Please note:

  • Typical pitch configurations are 45 Degree, 60 Degree, Rectangular pitch and 90 Degrees.
  • 60 Degrees at 30 Degrees, random perforations, decorative perforations and picture perf are bespoke.

Benefits of Choosing Perforated Metal

  • In its solid state, Perforated Metal Sheets are smooth with a high strength ratio especially when round holes are used. This makes it ideal for forming into three-dimensional shapes to increase strength and rigidity.
  • Perforated Metal sheeting is ideal for applications such as ceiling tiles, cladding, lamps, balustrade infill and much more. Visit our Project Gallery to view recent projects.
