Non-metallic Expansion Joint

Custom Fabric Expansion Joint Solutions for Heated Duct Systems

Our Non-Metallic Expansion Joints at Dutco Tennant LLC offer several advantages in plant design and building applications. They accommodate movements in multiple directions simultaneously, generate minimal reactive forces, require limited installation space, and are easy to transport and install. They can also be adapted to existing physical conditions without major structural modifications.

Each NMEJ is custom-built to suit the specific application, ensuring reliable performance across demanding industrial environments. We also offer metallic and rubber expansion joints across the GCC and the Middle East.
