Three main types of the scaffolding
Re-usable plastic scaffolding. These interlocking and modular systems are used to build widely variable, but relatively simple, concrete structures. The panels are lightweight and very robust. They are especially suited for low-cost, mass housing schemes
Traditional timber scaffolding. The scaffolding is built on site out of timber and plywood or moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring re-usable scaffolding. It is also the most flexible type of scaffolding, so even where other systems are in use, complicated sections may use it.
Engineered scaffolding Systems. This scaffolding is built out of prefabricated modules with a metal frame (usually steel or aluminium) and covered on the application (concrete) side with material having the wanted surface structure (steel, aluminium, timber, etc.). The two major advantages of scaffolding systems, compared to traditional timber scaffolding, are speed of construction (modular systems pin, clip, or screw together quickly) and lower life-cycle costs (barring major force, the frame is almost indestructible, while the covering if made of wood; may have to be replaced after a few - or a few dozen - uses, but if the covering is made with steel or aluminium scaffolding the form can achieve up to two thousand uses depending on care and the applications).
