Large silo installations require tremendous precision. Silo users demand an extreme tight silo for sanitary reasons. This pushes us to the limit regarding the individual silo parts tolerances. In particular, very tall silo installations are challenging.

Since we are talking modular silos, small tolerances in every single silo part may add up to a big tolerance 30 meters up. Resulting in an untight silo with contamination risks.

By using bolts and nuts combined with extreme precise silo parts, we force the single parts tight together. This enables us to keep total level tolerance <5mm @ +30mtr. The rounded bolt heads have a hygienic design. So that’s why we use bolts and nuts!
