The parallel chord or flat trusses gets its name from having parallel top and bottom chords. These flat roof trusses can therefore be used to build flat roofs and sometimes even floors. Usually, these will cover the shortest distance from the roof plane. Their number and the distance between each of them must be determined according to the loads, particularly snow, that the roof must be able to support.
