Commercial Flagpoles.

Your flagpole must be rated for the ASCE 7-10 basic wind speed at your location, measured as a 3-second gust at 33 feet above ground (50-year mean recurrence interval). NAAMM FP 1001-07 defines standard flagpole ratings at 85, 90, 100, 110, 120, 130, 150, and 170 mph. FlagCo manufactures poles rated from 85 to 170 mph depending on type, height, diameter, and wall thickness. Use FlagCo's Wind Speed Tool to look up the ASCE 7-10 wind speed for any U.S. zip code.

External halyard flagpoles (stationary and revolving) use an external rope and cleat to raise and lower the flag. They are available in heights from 15 to 80 feet. Internal halyard flagpoles route the halyard inside the pole shaft, accessed through a hinged door with a cam lock. FlagCo offers two internal halyard systems: Internal Winch (available 20 to 80 feet, uses a stainless steel cable with a geared winch mechanism) and Internal Cam Cleat (available 20 to 35 feet, uses a rope halyard with a cam cleat locking device). Internal halyard systems reduce vandalism and unauthorized lowering of the flag.

Set depths vary by pole height per NAAMM FP 1001-07: 15 and 20 ft poles require 2 ft, 25 ft requires 2.5 ft, 30 ft requires 3 ft, 35 ft requires 3.5 ft, 40 ft requires 4 ft, 45 ft requires 4.5 ft, 50 ft requires 5 ft, 60 ft requires 6 ft, 70 ft requires 7 ft, and 80 ft requires 8 ft. The overall pole length equals the exposed height plus the set depth. All ground-set poles ship with a steel ground sleeve.

Recommended flag sizes by pole height: 15 ft uses 3'x5', 20 ft uses 4'x6', 25 ft uses 5'x8', 30 to 35 ft uses 6'x10', 40 to 45 ft uses 8'x12', 50 to 55 ft uses 10'x15', 60 to 75 ft uses 12'x18', and 80 ft uses 15'x25'. Wind ratings published by FlagCo are calculated with the recommended nylon flag size attached. Nylon is the standard material for wind load calculations; if flying a polyester flag (which is heavier), the effective wind rating may be lower due to increased wind load on the pole.

FlagCo flagpole shafts are 6063-T6 aluminum per ASTM B 221, with a minimum tensile strength of 30,000 psi and minimum yield strength of 25,000 psi. All poles are cone-tapered. Structural blind rivets are 5056-H32 aluminum, 3/16-inch diameter, flush countersunk. Design follows the Aluminum Design Manual and NAAMM FP 1001-07.

A flagpole beacon is an aviation obstruction light mounted at the top of the pole, replacing the standard truck and finial assembly. Beacons may be required by the FAA for poles near airports, or used to illuminate the flag for nighttime display per U.S. Flag Code. FlagCo beacons are Intertek (ETL) certified and available in 110V AC and solar-powered configurations. External revolving poles support external beacons. Internal winch poles support IH beacons sized by pole top diameter. Cam cleat poles support cam beacons. External stationary poles do not support beacon installation. Use FlagCo's Beacon Selector to find the right beacon for your pole.

FlagCo flagpoles are available in three finishes: Mill (natural aluminum, no coating), Clear Anodized (satin finish with corrosion protection), and Powder Coated (custom RAL or manufacturer-standard colors for architectural matching). All finishes are applied to the 6063-T6 aluminum shaft.

The flash collar covers the gap between the flagpole shaft and the ground sleeve at grade level. FlagCo's standard spun aluminum flash collar is formed from sheet aluminum on a spinning lathe. The upgrade cast aluminum flash collar is poured into a mold for a heavier, more durable profile. Both are sealed with exterior-grade silicone sealant at the grade line.

ASCE 7-10 designates Special Wind Regions in areas where terrain features (mountains, gorges, ocean promontories) can cause localized wind speeds higher than what the standard wind speed map shows. These regions are marked with dashed red borders on ASCE 7-10 wind maps. If your project is in a Special Wind Region, the local Authority Having Jurisdiction (AHJ) may require a higher wind speed rating than the map value. Always verify site-specific wind requirements with the local building department before specifying a flagpole in these areas.
