The steel material used in the production of Chinese now have a steel tubular scaffolding, steel scaffolding ringlock, socket type steel scaffolding, gantry scaffolding, and there is a variety of scaffolding, hanging scaffolding pipes and other materials pick scaffold. It's material and construction proceeds with the case, which can be roughly divided as follows:

1) A single standard steel scaffolding. It only uses a standard steel scaffolding tube, such as steel tubular scaffold, only Ф48.3 × 3.5 welded pipes.

2) A combination of a variety of specifications of steel scaffolding. It consists of two or more different sizes of steel pipes, such as gantry scaffolding.

3) To the steel-based scaffolding. Namely steel-based, supplemented by other types of scaffolding steel rod member constituted as provided in the base of the channel backwater or scaffolding with connecting plate pick scaffolding. Cuplock steel scaffolding when used in the steel rail as a "single pipe scaffolding"; when using steel side rails take time, as the "steel-based scaffolding."

By way of transfer of the vertical force between the bar and the Pole division

1) By the friction force transmission contact surface. Namely by frictional contact surfaces at the node after pressing reaction force to support the rail loading and pass pole, such as the role of fasteners, bolts through positive pressure on the friction force;

2) By weld force transmission. Most of the bar and the Pole socket coupling is in this way, the frame scaffolding also belongs in this way;

3) Direct pressure force transmission. This way is more common in the bar resting on top of the scaffolding tube pole;
