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.

Our advanced and expert tooling department allows us to customize tooling to your exact requirements.
- Perforated patterns are available in one-hole size or a variety of different hole sizes and shapes
- Bespoke patterns and pitches are designed to individual customer’s requests
- Different Perforated Metal types are also available in flush, embossed (raised), countersunk and louvered
- Standard staggered pitch include; 60, 90 and 45-degree orientation
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.

- Medical: Autoclave and cadaver trays, ventilation hots, test tube holders. perforated equipment for the medical industry that are chemical resistant and offer filtration
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.
