**************************************************************************
NOTE: Use as many of the options as possible
consistent with functional requirements. Allow
Class 3, formed steel sections as an alternative if
no other requirements prohibit their use on a
particular job.Certain security applications using
intrusion detection sensors, must use steel pipe
framework only. For rails and braces, use minimum
sizes specified in FS RR-F-191/3 for each class and
grade unless members are to be oversized.
**************************************************************************
**************************************************************************
NOTE: Steel pipe is available in two grades: A or
B. Grade A is zinc-coated with 0.54 kg per square
meter 1.8 ounces per square foot of zinc.
Grade B
consists of a zinc-coating with 0.27 kg per square
meter 0.9 ounce per square foot, a chromate
conversion coating, followed by a clear acrylic or
polyester coating. The acrylic or polyester
coatings used on Grade B pipe should not be confused
with optional polyvinyl chloride (PVC) coatings
available for framework. Grade A pipe which has the
heavier zinc-coated interior may be desired in some
coastal regions located in highly corrosive
salt-laden environments to prevent rust caused by
condensation inside the pipe. Grade A or Grade B
pipe may be used in inland and desert areas,
provided Grade B pipe meets the salt spray test.
