Home > Fabric Structures > Double Truss

The Double-Truss style Portable Fabric Structures provides strength and functional performance in all seasons. The double-truss frame for this portable building is constructed from 1” square galvanized steel tubing and provides additional strength and durability to allow for wider buildings than the Quonset-style portable fabric building. These fabric buildings can be relocated and erected in a short period of time, making them great for warehouses, garages, crew tents or cook shacks used for commercial and personal applications.
