Double Mast Nautical flagpoles are designed to authentically match the original concept of the old double masted ship rigging's with the Stars & Stripes flying from the mast's gaff. The top & lower mast connecting bracket as well as the gaff and yardarm bracket are specially fabricated from aluminum plate and tubing, heliarc welded and finished to match the flagpole. The resulting flagpole is one of beauty, strength and authenticity. Please allow 3 - 4 weeks after approval for shipping.
Ground Set Cone Tapered Aluminum (6063-T6) Flagpoles
Our cone tapered ground set aluminum flagpoles are precision fabricated from new, 6063-T6 tubing utilizing the industry's most sophisticated 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. All foundation dimensions listed in this catalog 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.
All flagpole shafts are highly polished with fine grain aluminum oxide cloth resulting in a high quality, deep satin luster finish. This finish represents the ultimate in architectural finishes for aluminum flagpoles. The elegant, soft sheen remains maintenance free. The following anodized finishes are available as standard colors. Note: For bronze, dark bronze #313 is supplied unless otherwise specified.
"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, out of the tube, and off the ground. If the shaft is to be stored indoors, it may be left in the wrappings and the tube, provided that it shows no sign of having been exposed to moisture and that it will not be exposed to moisture during storage.
"CAUTION" - 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.
The 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.
PLEASE NOTE: Recommended flag sizes 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 over sized flags and banners or flying flags in higher winds than recommended.
Because wind speeds are usually not constant, and gusts are involved, flagpoles (both flagged and unflagged) are listed in this catalog with a constant wind speed and a 1.3 gust factor.
Flagpoles and their associated wind speeds listed assume that ten percent of the overall length of the flagpole is buried per or recommendations at or near ground level. Special engineering may be required for other applications such as wall or roof mounted flagpoles. Contact us for a prompt response regarding any situation that may require special engineering.
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 generally are 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.
It's 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.
