2.  The advantage of adjustable steel props     The Steel prop with reasonable and highly carrying capacity. At the construction site, it can effectively reduce the amount of prop, so that the workers can have a big operating space and can handling the materials smoothly. The speed of the set up is more 6 times than a traditional scaffolding and it can also save 70% Artificial than the traditional     The Steel prop without additional bracing and tripod-type were combined into an independent prop, stand-alone steel pillars form the basis of the whole structure
