NOTE: It is assumed that members will be protected
from the weather. If members will be exposed or
subject to moisture directly, by water infiltration,
or via vapor transmission and condensation or
indirectly in a corrosive atmosphere, delete carbon
steels (painted) and specify coating Class Z275 G90
for such members. Specify G40 for brick ties and
screw fasteners. See special option below for
deflection limit on exterior wall brick construction.
Grades specified are normally used for this type
of framing. See manufacturer's current literature
for other grades and section properties available.
