Mono trusses slope in one direction and are often used in low-level, lean-to style extensions. For this reason they are only able to span up to 10 meters although it is possible to modify the webs in order to increase this further where necessary.
At Minera Roof Trusses we often use mono trusses in combination with raised tie roofs and lattice trusses as shown in the image below. The lattice trusses will span along the apex between the raised tie trusses. The mono trusses will be used in the section below the rafters by hanging off the lattice trusses in order to add increased strength to the overall roof structure.
