@glasshouse as stevie k said it depends on the type of system being used and gauge of purlin.
Most 0.7mm box profile will span 1.80mtr but most agricultural buildings are set to 1375 to allow for fibre cement or steel sheets. For the sheeting anything between 1.20mtr & 1.50mtr should be fine for 0.7mm.
For the purlins this depends on the depth, gauge and if it is a butt or sleeve system.
