Custom Weld-Tec silos for long-term use
Zeppelin Systems, as a leading company in silo construction, guarantees premium long-term quality even with traditional welded silos. These are often requested for short distances to the installation site or smaller silo volumes. Additionally, for special structural or process engineering requirements, such as process silos due to design pressure/temperature or installations in mixing silos, traditional welded construction can be an excellent choice, provided the quality of the welding is ensured. Weld-Tec silos are available in aluminum or stainless steel.
