12.5. Hanger

When ceiling joists have to cover longer distances, it may be necessary to give them extra support. This is done with hangers. Hangers should be placed from one side right through to the other without any joints. The joining between ceiling joists and hangers is done with a fillet. Hangers are placed above joists at intervals of 1500 mm to 2000 mm.
