Tube and coupler scaffold, also known as tube and clamp scaffold, is a scaffolding mainly consisting of steel tubes and couplers. It allows connecting steel pipes and couplers at any interval, as long as there is no restriction due to engineering rules and regulations. Therefore, it can create a variable geometry scaffold system with strong adaptability to building and structures with complex geometries, and perform construction and maintenance works on the platform.

It can be flexibly assembled into birdcage scaffolding, suspended scaffolding and supported scaffolding. It is frequently used in refineries, petrochemical plant environments and power plants for construction, maintenance and restoration works. In addition, it can also be used to build ramps, sheds, stands and other temporary structures.
