Scaffolding is a temporary structure erected to support workers and materials during the construction, maintenance, or repair of buildings, bridges, and other man-made structures. It provides a safe and stable platform for workers to perform tasks at heights.

Here are some key aspects of scaffolding:

• Purpose: To provide a safe working platform at height.
• Materials: Typically made of steel or aluminum, but can also be made of timber or bamboo (in some regions).
• Components: Consists of posts, ledgers (horizontal supports), transoms (cross supports), and braces for stability, along with planks or platforms for the working surface.
• Safety: Must be erected, used, and dismantled according to safety regulations to prevent accidents.
