Supported Scaffolds

Types of Supported Scaffolds

Supported scaffolds consist of one or more platforms supported by legs, outrigger beams, brackets, poles, uprights, posts, frames, or similar rigid support. 1926.451(b)

Frame or Fabricated

Fabricated frame scaffolds are the most common type of scaffold because they are versatile, economical, and easy to use. They are frequently used in one or two tiers by residential contractors, painters, etc., but their modular frames can also be stacked several stories high for use on large-scale construction jobs. More information on this scaffold.

Tube and Coupler

Tube and coupler scaffolds are so-named because they are built from tubing connected by coupling devices. Due to their strength, they are frequently used where heavy loads need to be carried, or where multiple platforms must reach several stories high. Their versatility, which enables them to be assembled in multiple directions in a variety of settings, also makes them hard to build correctly.More information on this scaffold.
