Construction using aluminium profiles without any mechanical machining

In addition to purely structural profiles (with slots on all sides), a modern aluminium profile system should also offer a range of profiles that are both functional and visually attractive. Always keeping in mind RK Rose+Krieger’s philosophy -connection without machining - we have incorporated a range of functional and special profiles made from aluminium into our product portfolio which meet this requirement.
We have divided our "functional profiles" into three sub-categories: visible, frame and special profiles Depending on the profile geometry, they  can be assembled using the appropriate connecting technology, with no machining required. Simply cut the profiles to length and assemble, thereby reducing the planning and assembly work to a minimum!

Aluminium special profile and functional profile with smooth outer surfaces – stylish & secure

Smooth outer profile surfaces give machine frames a high-quality appearance compared to a slot profile. They are also much easier to clean, which can be a major advantage, or even a mandatory requirement, for certain applications. We supply our special profiles made from aluminium in a range of versions:

• Our angle profiles (W-profiles) are available in various angles and are connected together using corner joints (without any machining).

• The profiles that we call G-profiles are also available in various designs. 1-4 outer surfaces are completely closed, making these profiles ideal for use in hygienic areas.

• The clamping profiles (KL-profiles) allow panels in a wide range of thicknesses to be fastened. These profiles can be used to construct safety guards and cover hoods, for example.

The special profiles and functional profiles feature a specific geometry or function. They  can all be found in the profile overview. Buy aluminium special profiles from RK Rose+Krieger now!

Special profiles with specific geometry and/or function

These aluminium profiles are characterised by the smooth surfaces on one, multiple or four sides. Here, panels made from materials such as wire mesh, acrylic glass, Trespa, Makrolon etc. can be fitted deep into the profile and clamped firmly in place.

Principal areas of application:

  • Applications with greater design requirements
  • Environments in which the level of contamination should be kept to a minimum
  • Hygiene areas with a requirement for easy cleaning

Principal areas of application:

  • Safety guards
  • Screening
  • Covering hoods
  • Cladding

Principal areas of application:

  • Slot profiles with a flat design
  • Holders for light loads
  • Framework structures


  • F-G profiles: Geometry corresponds to the F-profile, but with closed surfaces – flange bracket connecting technology
  • W-profiles: Various angles between 30° and 90°, each with closed outer surface – connection corner joint


  • KL-profiles: Panels are clamped firmly into place using a clamping bar – connecting technology corner joint
  • ESP-profiles: Panels with a predefined thickness are inserted – connecting technology corner joint
