The FLIMU® System – Connecting Reinforcement

The extruded coupler splice – respectively, the FLIMU® system – has been developed especially for realizing reinforcing connections in large numbers or very limited space conditions.


When realizing a FLIMU® coupler splice, two reinforcing bars are connected by extruding a coupler that has been placed onto both ends of the reinforcing bars. A reducing ring is pushed over the coupler using a high amount of pressure. The reducing ring significantly reduces the exterior diameter of the coupler and creates a force fit connection between rebar and coupler (extrusion process).


Both B500 reinforcing steel with normal threads in accordance with DIN 488 and GEWl® reinforcing steel threadbar can be spliced using the FLIMU® system. This way, even reinforcing bars that have already been installed can be easily coupled to a GEWl® connecting bar. The FLIMU® system is also suitable for many similar reinforcing steel bars such as Austrian ARI and ARI-G.
