What is scaffolding made of?
Quality scaffolding is typically made of steel or aluminium. Aluminium scaffolding is ideal for short term use, while steel scaffolding is more suited to projects that will take longer and will involve heavier use. But bear in mind that steel scaffolding costs more and takes longer to setup.
Aluminium is lightweight, less expensive and easy to erect. But if your project is going to take a long time and will be labour intensive, then steel will be a better choice because of its sturdiness and resilience.
