TRUSSES AS BUILDING COMPONENTS
Efficient Components
Trusses are versatile and efficient framing
components. They are available in an almost
infinite combination of profiles, depths, and
internal web patterns, depending upon the
required building geometry and loads. The great
efficiency of trusses comes as the result of the
custom-design of almost every truss for its
particular location and application.
Truss Profiles
Truss profiles are usually the result of the need to
create specific roof planes and perimeter
conditions. Truss depths are usually driven by
roof planes and heel heights, but are also driven
by the need to create strength.
Truss Web Patterns
Truss web patterns are generated by the truss
designer to create the most efficient truss. Web
patterns are often tailored to allow more efficient
truss bracing. Patterns can also be tailored to
create clear paths (runs or chases) through the
web pattern to allow the passage of ductwork.
The creation of these runs can speed the
installation of mechanical systems.
Available Combinations
The trusses in these charts represent a fraction
of the possible combinations of truss span, load,
profile and depth. If you have a specific truss
configuration and you need load/span
information, please contact your local Authorized
TrusSteel Fabricator. You can find a list of these
