Types of Supported Scaffolds
Supported scaffolds are platforms supported by rigid structures such as legs, poles, uprights, posts, frames, brackets, or outrigger beams (as defined in OSHA Standard 1926.451(b)). These scaffolds are among the most common types used in construction and maintenance work because they provide stability, versatility, and accessibility.
1. Frame or Fabricated Scaffolds
Fabricated frame scaffolds—also known as frame scaffolds—are the most widely used type of supported scaffold. They are versatile, economical, and easy to assemble, making them popular among residential contractors, painters, and maintenance workers.
While often used in one or two tiers, these scaffolds can also be stacked multiple stories high for large-scale construction projects due to their modular design.
Key Features:
- Simple and quick assembly using pre-fabricated frames
- Suitable for a wide range of tasks and environments
- Can be used for both small- and large-scale operations
2. Tube and Coupler Scaffolds
Tube and coupler scaffolds are constructed using tubing connected by coupling devices, which allows for exceptional strength and flexibility. They are ideal for projects that require heavy load-bearing capacity or multiple elevated platforms reaching significant heights.
Their design enables them to be assembled in various directions, adapting to complex structures or irregular building layouts. However, this same flexibility means they require skilled assembly to ensure safety and stability.
Key Features:
- Extremely strong and adaptable for complex designs
- Suitable for heavy-duty construction work
- Requires precise setup to meet safety standards
