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. If the flag is not moving, then the wind speed is below 11 mph. Contact us for a prompt response regarding any situation that may require special engineering. Determine the maximum wind speed for your area utilizing the color chart provided. Flags of different sizes are designed to be flown from different poles. They are also higher in open country than in the center of cities. Find your wind speed on the chart below using both the Unflagged Wind Speed and the Flagged Wind Speed columns.

x .125in. (See the map below). Loads on flagpoles are resisted by the mounting foundation, roof, or wall to which it is secured. A fully extended flag flapping hard in the wind will be around 32 to 37 mph.

Wind exerts a force on the pole as well as the flag, thus both loads must be added to determine total load. Principal load acting on flagpoles is wind load and that load must be carefully determined. PLEASE NOTE: recommended flag sizes throughout this catalog do not represent a warranty that the flag size shown may be safely flown in all wind speeds.

Typically, consumers can expect higher wind speeds in coastal regions, but should always check the information for their particular area. All Rights Reserved.

Stage five: If … Personal injury, flagpole damage or property damage can occur when flying oversized flags and banners or flying flags in higher winds than recommended. Flag Pole Wind Speed Chart: Exposed Height (feet) Shaft Diameter (inches) Wall Thickness (inches) Unflagged Wind Speed (MPH) Flagged Wind Speed (MPH) Max. 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. Estimate the flapping of the flag. Remember There Are NEVER Additional Fees Because We Offer... (*Some exclusions apply. 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. A key element that cannot be overlooked in selecting the right flagpole is the maximum wind speed of the area the pole will be used. Wind exerts a force on the pole as well as the flag, thus both loads must be added to determine total load. Please review products on our website for current pricing. Stage two: If the flag is moving subtly and sporadically, then the wind speed with between 12-18 mph. Required fields are marked *. Stage three: If the flag is waving it’s entire length but in a gentle motion then the wind speed it between 19-24 mph. Wind speed also becomes greater as height above ground increases. Design of safe flagpoles requires knowledge of the loads to which they will be subjected. When selecting a flagpole, it is important to consider the maximum wind speeds. Aluminum Commercial External Halyard Flagpole, 30 ft. x 4 in.

If the flag is flapping over the whole length of the flag, it is blowing at around 19 to 24 mph. WARNING - recommended flag sizes do not represent a warranty that the flag size shown maybe be safely flown in all wind speeds. Measure how far the flag extends in the wind. For other questions please contact us at (800) 445-0653 or email us at sales@flagandbanner.com. Special engineering may be required for other applications such as wall or roof mounted flagpoles. American flagpole recommends flag sizes based on wind speed, pole height and the specific specifications per flagpole.

Areas with the same maximum constant or steady wind speed are indicated. Note: The wind velocity and flag size ratings used in the above map is based upon the National Association of Architectural Metal Manufacturers' Guide Specifications for the Design of Metal Flagpoles, NAAMM Standard FP-1-90. When selecting a flagpole, it is important to consider the maximum wind speeds. Generally, the higher the expected wind speed, the smaller the flag size that should be flown. The factors in helping you determine what Flag Pole is right for you are: wind zone area, flagpole height, base diameter, wall thickness, and the size of the Flag you want to fly. Flags of different sizes are designed to be flown from different poles. Because wind speeds are usually not constant, and gust are involved, flagpoles are listed with a constant wind speed and with a 1.3 gust factor.

The map below shows expected wind speeds for the next 50 years (since 1997) at 30 feet above ground level.
