MS Square Pipe can be used as shuttering support during concrete slab work. To use square tubes as shuttering support, the tubes are placed at equal intervals.

The distance between the tubes depends on the thickness of the slab and the load it is expected to bear. Once the square tubes are in place, the formwork is placed on top of them. The formwork is typically made of plywood or steel and is used to hold the wet concrete in place until it sets.
