The company Treppenbau "System-Krieger" GmbH has been involved in the development of staircase systems approved by the building authorities for more than 15 years and grants the manufacturing rights to competent staircase construction companies. In addition to the approval for the handrail-supporting staircase(ETA 06/0154), Krieger is also in possession of the approval for the WE1 staircase without supporting handrail, as well as the staircase in folded look(ETA 08/0133).
As the current trend is towards modern design with different material mixes, Krieger has developed a new staircase with HPL thin stringers in a flat steel stringer look(ETA-09/0252). Krieger has also recently received approval from the DIBT in Berlin for the morticed-in 40 mm stringer staircase(ETA-14/0122). This is currently the most comprehensive approval for this type of staircase on the market.

- the HPL panels can be processed with woodworking machines and CNC machines, no special software required
- finished surface, painting of the HPL stringers is not necessary, but can be done if required
- no screw connections and angles are visible on the visible side of the side panels
- no additional cross bracing required
- rational and inexpensive to manufacture, low accessory prices
- easy installation due to low weight and innovative screw connection technology
Stringer staircase mortised
Due to the recent ruling of the Federal Court of Justice (BGH), there is a great deal of uncertainty in the staircase industry. For this reason, Krieger-Treppen has carried out numerous large-scale tests with Prof. Dr. Ing. Irle and Prof. Dr. Kanz in order to obtain ETA approval for this type of staircase. Just in time for our partner meeting on July 4 and 5, 2014, we were granted approval by the German Institute for Building Technology in Berlin.
You are welcome to register with us for the next instruction seminars on the staircase system and cooperate with a strong community!
