map below shows the maximum steady wind expected at an elevation of thirty feet
above ground level within a fifty year period of recurrence. Areas with the same
maximum constant or steady wind speed are indicated. Because wind speeds are
usually not constant, and gusts are involved, flagpoles (both flagged and unflagged) are listed with a constant wind speed and a 1.3 gust
factor. "Warning" - recommended flag sizes throughout this site do not
represent a warranty that the flag size shown may be safely flown in all wind
speeds. Personal injury, flagpole damage or property damage can occur when
flying oversized flags and banners or flying flags in higher winds than
recommended. Flagpoles and their associated wind speeds listed assume that ten
percent of the overall length of the flagpole is buried per our recommendations
at ground level. Special engineering may be required for other applications such
as wall or roof mounted flagpoles. Consult an engineer or architect.
Design of safe flagpoles requires knowledge of the loads to which
they will be subjected. Principal load acting on flagpoles is wind load and that
load must be carefully determined. Maximum wind speeds to which flagpoles are
exposed depend on geographical location, whether or not it is in the center of a
large city, a small town's outskirts, seashore, at ground level or on the roof
of a high building. Wind speeds are generally higher along coastal areas than
inland. They are also higher in open country than in the center of cities. Wind
speed also becomes greater as height above ground increases. Wind exerts a force
on the pole as well as the flag, thus both loads must be added to determine
total load. Flags of different sizes are designed to be flown from different
poles. Obviously, it is important that flagpoles be selected which are capable
of supporting the largest flag intended to be flown in the highest wind speed to
which it will be subjected. Loads on flagpoles are resisted by the mounting
foundation, roof or wall to which it is secured.
General Information Ground Set Cone Tapered Aluminum Flagpoles
Our cone tapered
ground set aluminum flagpoles are precision fabricated from new, 6063-T6 tubing
utilizing the industry's most sophisticated, state-of-the-art manufacturing
processes. the conical portion tapers approximately 1" in every 5 1/2
feet. poles with overall lengths of less than 38' 6" are shipped in one piece.
longer lengths are shipped in sections and will be factory fitted with a
self-aligning sleeve which requires no field welding. Upon proper assembly a
hair-line joint will occur.
All poles are
double spiral wrapped with protective paper and shipped in a hard fiber tube.
"Warning" - The flagpole shaft will stain if allowed to remain in contact with
wet or damp wrappings. If there is any sign that the shaft or its shipping tube
has come in contact with water during shipment, remove it from the tube and
unwrap immediately. If the shaft is to be stored outdoors, it must be stored
unwrapped, and off the ground. if the shaft is to be stored indoors, it may be
left in the wrappings and tube, provided that it shows no sign of having been
exposed to moisture, and that it will not be exposed to moisture during storage.
All foundation dimensions listed in the
instructions are intended for general guidelines only in good, firm, dry soil. It is
recommended to consult and engineer for specific foundation dimensions suited to
your exact location. "Warning" - Extreme care must be exercised when installing
flagpoles near overhead power lines or when digging in the vicinity of buried
cable or piping. contact your local authorities before any digging.
All flagpole shafts are highly polished with fine grain aluminum
oxide cloth resulting in a high quality, deep satin lustre finish. This finish
represents the ultimate in architectural finishes for aluminum flagpoles. The
elegant, soft sheen remains maintenance free. In addition to satin, the
following anodized finishes are available as standard colors: clear, light
bronze #311, medium bronze #312, dark bronze #313 and black #335. Note: Of the
three bronze finishes, dark bronze #313 is supplied unless otherwise specified.
