Scaffold
Tube & Clamp Scaffolding: This is one of the earliest types of steel scaffolding and consists of two parts, including the tubes and clips, sometimes called ‘couples.’ The idea is really simple, and one reason why it’s so popular is because of the ease in assembly and disassembly. To erect the scaffold, you need to connect tubes together to make long runs and then connect the verticals and horizontals together with clamps built specifically for these tubes.
