When scaffolding is set up correctly, it provides workers with safe access to both single-story and multilevel building exteriors and interiors.
Article Updated on: October 02, 2026
Scaffolding used in construction gives crews access to an elevated work area, often the exterior of a building. There are several types of these temporary structures to choose from. One of the first things a contractor should consider when setting up a scaffold is the building's design and the kind of work that will be performed.
Scaffolding types
Different types of scaffolding can be used for the same type of work, so the choice often comes down to budget, the available space around the building and how long the work will take. The most frequently used types are supported scaffolding and suspended scaffolding.
Scaffolding Type | Category | Use Case | Space Requirements | Load Capacity | Mobility |
|---|---|---|---|---|---|
Frame scaffolding | Supported | Long-term projects (painting, stucco, multi-worker jobs) | Considerable space around the building | Supports multiple workers and equipment | Stationary |
Ladder jack scaffolding | Supported | Light maintenance or touch-up work at ladder height | Minimal space, attaches directly to ladders | Not designed for multiple workers or heavy equipment | Stationary |
Pump jack scaffolding | Supported | Small siding and painting jobs requiring variable work heights | Minimal footprint along vertical poles | Adjustable to task, best for lighter loads | Height-adjustable, not wheeled |
Mobile/ rolling scaffolding | Supported | Exterior and interior finish work needing horizontal access | Requires an even surface to roll safely | Varies by configuration | Moves easily on castors |
Suspended scaffolding | Suspended | Upper floors, tall buildings, window washing and repair | No ground footprint (hangs from overhead supports) | Platform-rated, motor-raised | Raised and lowered vertically |
Supported scaffolding: The most common type of scaffolding
Supported scaffolding is a network of poles or other members supporting horizontal platforms. These scaffolds consist of platforms that are supported by rigid structural supports such as outrigger beams, legs, poles or frames. The supports usually can be beefed up to accommodate the added weight of additional equipment and workers if necessary. Some standard supported scaffolding types are:
- Frame scaffolding: Frame scaffolding is stationary and built from the ground up. It's a popular and relatively inexpensive option for a long-term project. It's used in a variety of trades, including painting and stucco. It can support multiple workers and equipment. Frame scaffolds require a considerable amount of space around the building, so they are not always an option for limited-access spots.
- Ladder jack scaffolding: A ladder jack scaffold is constructed using two metal devices that attach to two ladders to create a stable base for a platform. This is a quick and easy solution, but it’s suitable only for light jobs like maintenance or touch-up at no more than ladder height. It is not designed to support multiple crew members or heavy equipment.
- Pump jack scaffolding: A pump jack scaffold is supported by moveable brackets on vertical poles. It’s easily adjusted, like a car jack, and works well for small siding and painting jobs and any other task that requires work at variable heights.
- Mobile/rolling scaffolding: Mobile scaffolding, also known as rolling scaffolding, is set on castors, so it can be moved easily to another section of work, assuming you have an even surface. It’s ideal for work on exterior and interior finishes, where contractors need extended horizontal access along the surface.
Suspended scaffolding: Good for upper floors and tall buildings
A suspended scaffold, also known as a hanging scaffold, consists of a platform with a guardrail system that can be raised up and down by ropes connected to an electric motor positioned on the roof.
Suspended scaffolding is a good choice when work is located at the exterior upper floors of a building or when the building is so tall that erecting frame scaffolding is not practical. Window washing, repair and other maintenance contractors use suspended scaffolding.
OSHA requirements for scaffolding
No matter the type of scaffolding, contractors should follow all the safety rules and OSHA guidelines for assembly, use and tear-down. OSHA provides a guide for the proper use of scaffolding in the construction industry.
