FDBIIFiligran Trägersysteme GmbH & Co. KG is searching for partners in Europe, North America, Asia and Russia regarding the patented Filigran® - Punching Shear Reinforcement (FDB). Different business models are possible.


Flat slabFiligran Trägersysteme GmbH & Co. KG has developed a special punching shear reinforcement to avoid punching shear failure in flat slabs and to increase the load-bearing capacity of the slab. Typical for this patented reinforcement is the anchorage of the inclined bars by a combination of loops and welding plus effective geometry.


column head vs FDBIIReinforced slabs are built economically as two-way span constructions. The application of FILIGRAN-Punching Shear Reinforcement makes it possible to avoid beams and column heads.


180709 Diagramm FDB Sulen ErhhungsfaktorBy the use of the Filigran - Punching Shear Reinforcement the punching shear resistance is more than doubled. The German Institute for Building Technology (DIBt) issued a European Technical Approval (ETA) and approved an increased load factor of 2.1, a factor higher than any other European-wide approved punching shear reinforcement system. The FILIGRAN - Punching Shear Reinforcement can be used in precast composite constructions as well as in in-situ slabs and is successfully used in Europe.


Filigran Trägersysteme GmbH & Co. KG is searching for partners in Europe and especially in South Korea, Japan, China, India, United States of America, Canada and Russia. We are open about the way of cooperation. It is possible to buy the product from Filigran Germany and sell it local, produce it in license or to take over our patent. Let us talk about the possibilities. If you are interested in a cooperation please contact: Dr.-Ing. Johannes Furche (This email address is being protected from spambots.
