What Is A Truss Screed

Typically, this truss system is mounted on rails on the formwork. The truss remains at a constant elevation as it moves across the slab surface. When spanning long distances, trusses should not flex because of their rigidity. This will result in a flat and level floor.
Truss sections range from 1 to 3 meters in length, and the sections can be joined together to form structures up to 20 meters long. For screeding wide bay pours, the truss screed is an excellent choice. While the truss is being used, a motor vibrates it. By compacting the concrete as well as screeding it, no pokers are needed
