GENERAL REQUIREMENTS
**************************************************************************
NOTE: Metal roof panels are capable of spanning the
structural supports and resisting snow, dead, live,
concentrated, and wind loads without benefit of
additional substrate materials. Substrates provided
in conjunction with SSSMR systems are not a
requirement of this specification and are referred
to as roof decks.
For Government designed buildings, the roof framing
system must show necessary structural framing
members, purlins, or subpurlins to accommodate
concealed anchor clip spacing. Concealed anchor
clip spacing cannot exceed 760 mm (30 inches) on
center in the high wind areas, generally at eaves,
rakes, and ridges, and 1.4 m (5'-0") on center for
the remainder of the roof. All concealed anchor
clips must be attached to the framing system. Clip
attachments to metal decks or other substrates are
not permitted.
Valleys must be properly designed to ensure that
water does not travel up under the offset cleat
where the panel terminates. Valley backup plates
shall be large enough to carry the valley flashing
and the panel terminations. Subpurlins must have
