In construction, the four main types of scaffolding are:

1. Single scaffolding(also called bricklayer’s scaffolding) – used primarily for brick masonry. It consists of a single row of standards (vertical poles) parallel to the wall, with putlogs inserted into the wall for support.

2. Double scaffolding (also called mason’s scaffolding) – used for stone masonry where holes cannot be made in the wall. It has two rows of standards (one near the wall, one outside) to provide greater stability and support.

3. Cantilever scaffolding(also called needle scaffolding) – used when the ground cannot support a scaffold, such as near roads or over obstacles. The scaffold is supported by needles (projecting beams) inserted into the wall or floor.

4. Suspended scaffolding – used for high‑rise buildings or repair work. The platform is suspended from the roof or top structure by ropes or chains and can be raised or lowered as needed.

These four types cover the most common configurations based on structure, support method, and application.
