About Us


" The bitterness of poor quality remains long after the sweetness of low price is forgotten " Benjamin Franklin



FILIGRAN S.A. belongs to a family-business in its third generation. The historical development and market launch of the FILIGRAN® construction method in collaboration with our customers continues to shape our DNA today. We see ourselves as a stable partner for our customers, and also act accordingly in the overriding interests of the industry.

Our fundamental attitude of working in partnership, which characterises us in the market, also explicitly includes our suppliers, financiers and employees, as we are convinced of the long-term superiority of fair dealings with one another. Fortunately, successful "fair play" is also more fun.

From Herby we serve mainly the market in Poland, but are increasingly present in other countries in the region too.




Stefan Keller founds FILIGRAN BAU Stefan Keller GmbH in Germany, now operating under his grandchildren as FILIGRAN Trägersysteme GmbH & Co. KG. The same year he patents the first lattice girders and lattice girder manufacturing machines.


Precast concrete units and beam-block floors are patented and introduced to the market.


The FILIGRAN®-floor slabs are developed and introduced to the market.


The FILIGRAN®-walls are developed and introduced to the market in the years 1970-75.


Introduction of the FILIGRAN®-system to Eastern Germany, Poland and Czechoslovakia.


The predecessor of FILIGRAN Sp. z o.o. is set up in Poland by a grandson of Stefan Keller, establishing the first state-of-the-art production for high-quality lattice girders in Poland.


Introduction of the FILIGRAN®-system to Russia, and Ukraine.


FILIGRAN Sp. z o.o. moves to its newly acquired production-facility in Herby near Częstochowa, and adds cold laminated reinforcement steel in bars and coils to its production program.


A machine for the special EQ-lattice-girder is acquired, making FILIGRAN Sp. z o.o. the only Polish producer who offers this effective product for dynamic loads and high sheer forces.


After only one year the second production-site in Warsaw is closed due to the massive impact of the financial crisis on the Polish construction sector. All production activities are bundled in Herby, the focus lies on constant improvement of productivity and quality.


Two special machines are acquired to produce lattice girders with a double lower-chord. This product makes the handling of reinforcement during the production process of our clients easier, and helps so save steel.


A new, competitive, fast and easy to handle window-lintel reinforced with a lattice-girder is introduced to the market in co-operation with our clients.


FILIGRAN SP. z o.o. is transformed into FILIGRAN S.A. to prepare for the future. With the installation of an EVG double-step-machine FILIGRAN® now has the most modern and fastest lattice-girder-automat in Poland. The existing facilities in Herby are significantly expanded and improved to maximise productivity, and increase speed of delivery.
