Tubular Scaffolding is a type of scaffolding consisted of Scaffolding Tubes and Scaffolding Couplers. The main advantage of the Tubular Scaffolding is that horizontal tubes with walking decks can be placed at any height of vertical tubes. At the same time, vertical tubes can be spaced at any distance apart. Maximum distances are restricted only by engineering constraints. Tubular Scaffolding requires a lot of labor input for assembly because it is not a modular system. Generally, it is used for work on non-rectangular, curved and irregular shaped structures, where unlimited versatility is needed. This type of scaffold is very popular in North American nuclear power plants. Vertical Scaffolding Tubes are connected to horizontal with Right Angle Rigid Scaffolding Couplers.

It is obvious that rigid Scaffolding Couplers do not allow rotation of elements. They can be connected only with right angles.

Diagonal Scaffolding Tubes which are used to stabilize scaffold are connected with Swivel Scaffolding Couplers. It is noticeable that transoms, which bear decks, are connected to standards on higher than longitudinal ledgers. It is done so to ensure that if the Scaffolding Coupler that holds bearing transom fails or slips down it will find support on the ledger.

Tubular Scaffolding is for sure the most versatile scaffolding system on the market. With movable Scaffolding Couplers, it is possible to adjust the system to any conditions, creating different distances between the elements. The problem is that the rigidity of Scaffolding Coupler joints might be insufficient and also the labor input which is needed for assembly is too high.
