Scaffolding system is a temporary framework applied in the construction project or repair of high rise buildings and other large structures. Usually, scaffolds are made of steel pipes or bamboos. Steel pipes are the preferred material due to its high strength. The steel tubes used for scaffolding purpose are called scaffolding steel tubes. Bamboos are still popular in some Asian countries and regions due to its easy availability and cost-effectiveness. The main reason why we erect a scaffolding system is to provide a safe working platform for workers who are working in high rise structures.

In addition to the scaffolding system using scaffolding steel tubes, there are also other kinds of scaffolding system: 1)The birdcage  2)Independent scaffolding  3)Single pole scaffolding  4)Swingstage scaffolding  5)Suspended scaffolding  6)Hanging bracket scaffolding  7)Cantilever scaffolding

The key parts of a basic scaffolding are Ledgers, Standards, and Transoms.

Standards are vertical scaffolding steel tubes which are used to transfer the entire weight of the scaffolding system to the ground where the scaffolding erects. Ledgers are horizontal poles used to connect standards. Transoms are always kept in the way which makes the right angle with the ledgers. It is a common practice to place main transoms next to the standards to hold the standards in place and to provide extra support to the platforms. Main transoms will be connected by intermediate transoms to provide extra support to the platforms as well as the scaffolding.

In order to erect a scaffolding system successfully, solid foundations are absolutely essential. Even though scaffolding system can be used without foundations, in some conditions such as concrete or similar hard surfaces, it is highly recommended to use base place irrespective of the condition of the floor. The working platform should also meet safety requirements. These platforms must be close boarded, have enough space and have double guard rails. Since almost all the scaffolding is dependent structures, the different frameworks used should be tied and fixed by scaffolding couplers to provide stability and security to the scaffolding system.
