Aluminum profiles

Aluminum profiles from RK Rose+Krieger – connecting profiles without the need for further machining

BLOCAN® profile system – Connection of aluminum profiles without any machining

No drill holes required to hold profiles together! Simply cut the aluminum profiles to length and assemble them!

These unique aluminum profiles were specially designed to save you time and money. Clever connection elements dispense with the need for machines and equipment. The profiles are simply cut to length and assembled and are available in more than 100 different profile sizes and cross-sections.

Special connectors for aluminum profiles save preparation and assembly time

RK Rose+Krieger connecting technology saves time in preparation and assembly.

Our BLOCAN® aluminum profile system – the benefits

  • combine, assemble, modify
  • maximum flexibility, with no need for mechanical machining of the aluminum profiles
  • reliable connecting technology that has been field-tested over many years ("long-term stability")
  • cost-effective due to low assembly costs, assembly position can be subsequently changed  
  • wide range of aluminum profiles in stock, with cross-sections from 20 mm to 320 mm
  • available as bars or cut-to-length (marked, deburred, ready for installation)
  • all profile systems compatible with one another
Construction profiles made of aluminum

Aluminum functional/special profiles

As well as construction profiles (with slots on all sides), a modern aluminum profile system should also include a range of profiles that are both functional and visually attractive. Without losing sight of RK Rose+Krieger’s philosophy – connection without machining – our product portfolio now includes a series of functional and special profiles made from aluminum that fulfil this requirement.


  • Attractive design
  • Multi-functional
  • Flexible
  • Cost optimization

Heavy-duty aluminum profiles

Heavy-duty profiles

Heavy-duty aluminum profiles – the alternative to steel construction

Used in combination with thrust connectors, BLOCAN®-heavy-duty aluminum profiles with a slot width of 18 mm offer many advantages in the classic mechanical engineering sector.

The aluminum profiles are pressure-connected and offer a highly load resistant screw connection which can be released at any time. No mechanical machining of the aluminium profiles is required, which means that assembly costs are significantly lower when compared to other profile systems and steel constructions.



  • Ability to absorb high dynamic loads
  • Large structures
  • Easy to transport (aluminum construction can be separated into segments)
