Using a floor truss system provides several advantages over using a joist floor system. With floor trusses, longer clear spans can be achieved allowing for a more open concept. The greatest advantage to floor trusses is what you don't see. With floor trusses using a web, verses a solid joist, the floor truss leaves a space to run mechanical, plumbing and electrical. Floor trusses allow for a wide range of bearing options that result is a smooth ceiling free of dropped beams and mechanical bulkheads.
