Steel props are most widely used in the construction of subway projects and also most used with various styles and types. The most

ubiquitous types are the r shape and crossing shape. And the intersection materials can be the steel tubes, the H style steel tubes with

the function of the strength the stability of the whole structures. And the intersection of the purline can be H shape steel.

1.   As the adjustable steel props enjoy a wide range of applications with reasonable and higher load bearing range. Thus the applied

quantity can be reduced to a great extent so as to lower the construction cost. The steel props will not be confined by the size of the

construction area and the space between the bracing tubes and the horizontal and longitudinal beams can be adjusted and changed

without being influenced by the transverse connecting tubes.

2.   For the same formwork size, the adjustable steel props used is less than that of the cuplock scaffolding and the steel tubular

scaffolding.

3.   The spared operation space is relatively large so the workers can be freely to walk through the construction site.
