The Formwork Supporting System is developed with the progress of the formwork engineering. At present, the supporting system of many countries has developed into various special construction tools, forming various series of products. For a long time, the supporting system accompany with the wooden formwork project commonly uses wooden support and bamboo support.

In the early of 20^th century of the UK, the steel pipe bracket composed of connecting parts and steel pipes was first applied, and gradually developed into the steel pipe scaffolding with fastening parts or we so-called Tubular Scaffolding. As this kind of bracket has the characteristics of simple processing, flexible dis-assembly and erection, convenient transportation and strong versatility, it is quickly popularized and applied to all countries in the world. At present, various forms of steel tube bracket for fasteners have been formed in many countries, and become one of the most commonly scaffolding system used to support Formwork System.

In the 1930s, adjustable steel prop were invented in Switzerland. This is a single steel prop whose height can be adjusted by using a screw jack. This kind of prop has been widely used in many countries because of its simple structure, flexible dis-assembly and assembly. Its structure can be divided into two types:  screw thread exposed prop and screw thread closed prop. Compared with the screw thread exposed steel prop, screw thread closed steel prop has the advantages of preventing the dirt such as mortar from freezing the screw thread, protecting the screw thread from being damaged in using and handling. Therefore, the screw threaded closed steel props are widely used in some European countries.

Since the 1980s, in order to increase the use function of the acrow steel prop, many countries have made improvements on the spigot and the top attachment of the steel standard, which greatly increased the function of the steel standard. There is also a collapsible tripod attached at the bottom, which makes the single-tube type pillar can be installed independently, which is more conducive to the installation and disassembly of the acrow steel prop.
