About us
Flexsabo Silo- und Anlagenbau GmbH, founded in 1996, is a manufacturer of flexible silos for the storage of animal feed, grain, mineral feed and wood pellets. The silos are made of high-strength, single-side coated polyester fabric and are guided in steel frames; for outdoor silo systems, the company manufactures specially dimensioned, hot-dip galvanized steel frames. As a certified welding specialist company according to EN 1090 (execution class up to EXC3), Flexsabo manufactures and welds the load-bearing steel components in its own production using the MAG, TIG and stud welding processes. In addition to the silo variants, the portfolio also includes accessories for silo systems as well as the planning and implementation of complete silo projects, including consulting and quotation preparation. Customers come primarily from agriculture (free-stall barns, feed storage), grain storage, and biomass/wood pellet heating. The company is located in Osterburken on the border between the Neckar-Odenwald district and the Main-Tauber district and delivers throughout the German-speaking region.
