Bespoke Engineered Metal Products

A unique approach to lettering created through the use of ‘perforations’ to create text. Otherwise known at Graepels as ‘Alpha-Perf’. Depending on your preferences, you can now choose from a variety of perforated metal fonts for your project. Graepels have over 60 years of industry knowledge, experience and expertise and our team are on hand to help you with any requirements you may have.
Graepels understands the importance of innovation. As a result, we developed ‘Alpha-Perf’ which is both aesthetically pleasing and functional, allowing customers to create remarkable designs using perforated text.

Alpha Perf offers different fonts to meet customer needs. The Alpha-Perf process involves perforating text into sheet metal. Perforations are created by punching hundreds or even thousands of holes into metal surfaces. These perforations can consist of various size holes which gives alternative densities of shading. Larger holes are used to give a stronger contrast whereas smaller holes are used for detail.

Combining Picture-Perf or Decorative Metal Sheets with Alpha Perf can result in some truly stunning results.
