The standard Nucor eave or rake extension is an extension of the
roof purlin system, and therefore follows the profile of
the main building roof line. Unlike the canopy beam, the
structural components (beams and/or purlins) are completely
enclosed within the soffit panel system.
is used with eave/rake extensions as a standard to allow
for a cleaner flashing condition. Soffit material shall
run parallel with the roof line. Nucor’s standard
soffit panel configuration shall be Nucor Classic Wall™ panel. Standard eave/rake extension projections
are 2’-0” and 4’-0”.
cannot continue further than the sidewall steel line. Roof
extensions beyond the sidewall steel line will be considered
an eave extension. Similar to canopies, eave extensions
must start and stop at frame lines. Finally, as with canopies,
any deviations from these standard limitations may require
non-standard framing methods to be priced for the project.
