Description

A scissor Howe truss is a type of truss that is used in buildings to support a pitched roof. The bottom chords of the truss are inclined, connecting to the rafters. This is in contrast to most other trusses, where the bottom chords are horizontal. Scissor Howe trusses are named after their resemblance to a pair of scissors. They are often used in buildings where a sloping or raised ceiling surface is desired. Scissor Howe trusses are also known as scissors trusses or Howe scissors trusses.
