What is the difference between external halyard and internal halyard flagpoles?

External halyard flagpoles run the rope on the outside of the shaft and secure it to a cleat at the base. They are available from 15 to 80 feet and are the most economical commercial option. Internal halyard flagpoles route the rope or cable fully inside the shaft, accessed through a cam-locked milled door, which prevents tampering and unauthorized flag lowering. Flagpole Warehouse offers two internal systems: Internal Winch (stainless steel cable with geared winch, 20 to 80 feet) and Internal Cam Cleat (rope halyard with cam cleat lock, 20 to 35 feet).

What aluminum alloy are commercial flagpoles made from?

All commercial pole shafts available through Flagpole Warehouse 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 shafts are cone-tapered. Structural blind rivets are 5056-H32 aluminum, 3/16-inch diameter, flush countersunk. Design follows the Aluminum Design Manual (ADM) and NAAMM FP 1001-07.

What is a flagpole beacon and when is one required?

A flagpole beacon is an aviation obstruction light mounted at the top of the pole in place of the standard truck and finial. Beacons may be required by the FAA for poles located near airports, or installed voluntarily to illuminate the flag for 24-hour display per the U.S. Flag Code. Beacons sold through Flagpole Warehouse are Intertek (ETL) certified and available in 110V AC and solar configurations. External revolving poles accept a top-mounted external beacon. Internal winch and cam cleat poles accept an internal beacon sized by the pole's top diameter. External stationary poles do not support beacon installation.

What is the difference between a spun aluminum and cast aluminum flash collar?

Both collar types seal the gap between the flagpole shaft and the ground sleeve at grade level using exterior-grade silicone. The standard spun aluminum flash collar is formed by spinning flat aluminum sheet over a lathe mandrel, producing a lightweight, cost-effective profile. The cast aluminum flash collar is poured into a mold, creating a heavier wall, a more defined architectural appearance, and greater resistance to impact at grade. Both are available through Flagpole Warehouse.

What is an ASCE 7-10 Special Wind Region and how does it affect flagpole selection?

ASCE 7-10 designates Special Wind Regions in areas where local terrain — mountains, gorges, coastal promontories — can produce wind speeds significantly higher than the standard contour map indicates. These regions are outlined with dashed borders on the ASCE 7-10 wind speed maps. For projects in a Special Wind Region, the Authority Having Jurisdiction (AHJ) may require a site-specific wind study or a higher rating than the map value shows. Always confirm the required design wind speed with the local building department before specifying a flagpole in these areas.

Q: What wind speed rating do I need for a commercial flagpole?

Your flagpole must be rated for the ASCE 7-10 basic wind speed at your project location — a 3-second gust at 33 feet above ground with a 50-year mean recurrence interval. NAAMM FP 1001-07 defines standard rating increments at 85, 90, 100, 110, 120, 130, 150, and 170 mph. Flagpole Warehouse carries commercial aluminum poles rated from 85 to 170 mph depending on type, height, butt diameter, and wall thickness. Use the Wind Speed Tool at flagpolewarehouse.com to look up the ASCE 7-10 design wind speed for any U.S. zip code before specifying.

Q: How deep should a ground-set flagpole be buried?

Set depths follow NAAMM FP 1001-07 and scale with pole height: 15 and 20 ft poles require 2 ft of burial, 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. Overall pole length equals the exposed height plus the set depth. All ground-set poles from Flagpole Warehouse ship with a matching steel ground sleeve.

Q: What flag size should I fly on my commercial flagpole?

Standard flag-to-pole size pairings: 15 ft uses 3x5 ft, 20 ft uses 4x6 ft, 25 ft uses 5x8 ft, 30 to 35 ft uses 6x10 ft, 40 to 45 ft uses 8x12 ft, 50 to 55 ft uses 10x15 ft, 60 to 75 ft uses 12x18 ft, and 80 ft uses 15x25 ft. Wind ratings published by Flagpole Warehouse are calculated with the recommended nylon flag attached. Flying a polyester flag or an oversized flag increases wind load on the pole and may reduce the effective rated wind speed for that configuration.

Q: What finishes are available for commercial flagpoles?

Commercial flagpoles at Flagpole Warehouse are available in three finishes: Mill (natural aluminum with no surface coating), Clear Anodized (satin appearance with an anodic oxide layer for corrosion resistance), and Powder Coat (applied color for architectural matching or custom RAL colors). All finishes are applied to the 6063-T6 aluminum shaft after fabrication.

Commercial Flagpole Types

Commercial aluminum flagpoles are organized by halyard system (external or internal) and structural class (standard or reinforced). External halyard poles secure the rope to a cleat at the base — stationary models hold the flag in a fixed position, while revolving models use a truck that rotates 360 degrees to prevent flag wrap. Internal halyard poles route the rope or cable inside the shaft and are accessed through a cam-locked door, making them resistant to vandalism and unauthorized flag lowering. Reinforced variants carry higher wind ratings for coastal and hurricane-prone installations. All types are covered by the cut sheet builder above.

External Stationary

External rope and cleat with a fixed flag position. The most economical commercial flagpole option for standard installations. Beacon mounting is not supported on this type.

15 to 35 ft

External Revolving

External rope with a 360-degree revolving truck that keeps the flag from wrapping the shaft in variable winds, reducing wear and extending flag life. Supports a top-mounted external beacon.

20 to 80 ft Beacon Compatible

Internal Winch

Stainless steel cable on a geared winch, fully enclosed in the shaft. Raised and lowered through a cam-locked access door. Standard specification for government buildings, schools, and high-security sites.

20 to 80 ft Beacon Compatible

Internal Cam Cleat

Internal rope halyard locked by a cam cleat device inside the shaft. Compact access door profile. Provides anti-vandalism security in a lighter-duty internal halyard format.

20 to 35 ft Beacon Compatible

Reinforced Winch

Heavy-wall internal winch pole engineered for elevated wind exposure — coastal zones, hurricane-prone regions, and other high-wind sites. Compatible with internal beacon.

25 to 50 ft Beacon Compatible

Reinforced Cam Cleat

Heavy-wall internal cam cleat pole for high-wind installations. Internal halyard for vandal resistance with the structural capacity of an upgraded wall thickness.

25 to 35 ft Beacon Compatible

Wind Speed Ratings: External Revolving Flagpoles

Rated wind speed (mph) by height, butt diameter, and wall thickness for external revolving commercial flagpoles. "With Nylon Flag" is the NAAMM FP 1001-07 compliance rating — the maximum wind speed the pole sustains with the recommended nylon flag attached. "Unflagged" is the bare-pole structural limit. Nylon is the standard fabric for wind load calculations; polyester flags add greater load due to higher fabric weight and may reduce the effective rated wind speed. All values per ASCE 7-10 (3-second gust at 33 feet above ground, 50-year mean recurrence interval).

Wind Speed Ratings: Internal Winch Flagpoles

Rated wind speed by height, butt diameter, and wall thickness for internal winch commercial flagpoles. All "With Nylon Flag" values assume the standard nylon flag for that height is installed. Internal winch poles use a stainless steel cable on a geared winch mechanism enclosed within the shaft, accessed through a cam-locked milled door. This is the most common anti-vandalism specification for government, institutional, and high-security installations.

Wind Speed Ratings: External Stationary Flagpoles

Rated wind speed for external stationary flagpoles, the most economical commercial configuration available. Heights range from 15 to 35 feet. The flag is attached to an external rope halyard and tied off to a base cleat; the flag position is fixed. Beacon installation is not available on stationary poles. All "With Nylon Flag" values assume the standard nylon flag for that height is attached, per NAAMM FP 1001-07.

Flagpole Foundation and Set Depth Specifications

All ground-set commercial aluminum flagpoles ship with a steel ground sleeve. The sleeve is embedded in a concrete foundation before pole installation; the pole inserts into the sleeve after the concrete cures. Set depth (burial depth) follows NAAMM FP 1001-07 standards and scales with exposed pole height. Overall manufactured pole length equals the exposed height plus the set depth. A spun aluminum flash collar (standard) or cast aluminum flash collar (upgrade) seals the gap between the shaft and sleeve at grade, finished with exterior-grade silicone. All ground sleeves include a factory-welded grounding lug for lightning protection bonding.

Frequently Asked Questions

What wind speed rating do I need for a commercial flagpole?

The required rating equals the ASCE 7-10 basic wind speed at your project location — a 3-second gust at 33 feet above grade with a 50-year mean recurrence interval. NAAMM FP 1001-07 defines standard rating increments at 85, 90, 100, 110, 120, 130, 150, and 170 mph. Select a pole whose "With Nylon Flag" value in the tables above meets or exceeds your site wind speed. If your site falls within an ASCE 7-10 Special Wind Region, confirm the required design speed with the local Authority Having Jurisdiction before ordering.

What is the difference between external and internal halyard flagpoles?

External halyard poles run the rope on the outside of the shaft and secure it to a cleat at the base. They cover 15 to 80 ft and are the most economical option. Internal halyard poles route the rope or cable fully inside the shaft, accessed through a cam-locked door — eliminating the external rope that can be cut or tampered with. Two internal systems are available: Internal Winch (stainless cable, geared winch, 20–80 ft) and Internal Cam Cleat (rope halyard, cam cleat lock, 20–35 ft).

What is a revolving truck and why does it matter?

The truck is the fitting at the top of the pole that carries the pulley (sheave) for the halyard rope. On a stationary pole the truck is fixed. On a revolving pole, the truck assembly rotates 360 degrees around the shaft. In shifting winds this keeps the flag from wrapping the pole, which reduces flag abrasion and extends service life — an important consideration on high-traffic or high-visibility sites where frequent flag replacement is costly.

How deep does a ground-set flagpole need to be buried?

Set depths follow NAAMM FP 1001-07: 15–20 ft poles require 2 ft of burial; 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; 80 ft requires 8 ft. The steel ground sleeve ships with the pole and is sized to match. Overall pole length equals exposed height plus set depth.

What flag size should I fly on my commercial flagpole?

Standard pairings: 15 ft → 3'x5', 20 ft → 4'x6', 25 ft → 5'x8', 30–35 ft → 6'x10', 40–45 ft → 8'x12', 50–55 ft → 10'x15', 60–75 ft → 12'x18', 80 ft → 15'x25'. Wind ratings in the tables above are calculated with the recommended nylon flag attached. Flying a larger flag or a heavier polyester flag increases wind load and effectively lowers the usable wind rating for that configuration.

What aluminum alloy are these flagpoles made from?

All commercial pole shafts are 6063-T6 aluminum per ASTM B 221. Minimum tensile strength is 30,000 psi; minimum yield strength is 25,000 psi. Shafts are cone-tapered. Structural blind rivets are 5056-H32 aluminum, 3/16-inch flush countersunk. Design per the Aluminum Design Manual and NAAMM FP 1001-07.

When is a flagpole beacon required, and which pole types support one?

A beacon (aviation obstruction light) may be required by the FAA for poles located near airports, or installed voluntarily for 24-hour flag display per the U.S. Flag Code. External revolving poles accept a top-mounted external beacon. Internal winch and cam cleat poles accept an internal beacon sized by the pole's top outside diameter. External stationary poles do not support beacon installation. All beacons are Intertek (ETL) certified, available in 110V AC and solar configurations.

What finishes are available?

Three finishes are available: Mill (natural aluminum, no surface coating), Clear Anodized (satin appearance with an anodic oxide layer for corrosion resistance), and Powder Coat (applied color for architectural matching or custom RAL colors). All finishes are applied to the 6063-T6 shaft after fabrication.

What is the difference between a spun and cast aluminum flash collar?

Both collar types cover the gap between the pole shaft and ground sleeve at grade and are sealed with exterior silicone. The standard spun aluminum flash collar is formed by spinning flat aluminum sheet over a lathe mandrel — lightweight and cost-effective. The cast aluminum flash collar is poured into a mold, producing a heavier wall, a more defined architectural profile, and greater resistance to impact at grade level.

What is an ASCE 7-10 Special Wind Region?

ASCE 7-10 designates Special Wind Regions — typically mountainous terrain, coastal promontories, and canyon corridors — where local topography accelerates winds above what the standard contour map shows. These areas are outlined with dashed borders on the ASCE 7-10 wind speed maps. Projects in Special Wind Regions require site-specific wind data or confirmation from the local building department; do not rely on the map contour value alone.

How do I generate a flagpole cut sheet or specification document?

Use the Cut Sheet Builder at the top of this page to configure a specific pole (type, height, diameter, wall thickness, finish, accessories) and download a PDF with an engineering drawing, specifications table, and wind rating data. The generated cut sheet is formatted for contractor submittals, architect review, and federal project submittal packages.

Can the cut sheet be used for federal project submittals?

Yes. The PDF cut sheet produced by the builder is formatted for inclusion in federal and state project submittal packages. It contains an engineering drawing, a complete specifications table, and NAAMM FP 1001-07 wind rating data for the exact pole configuration selected — the standard documentation required for contractor submittals, government procurement, and architect review sets.

All specifications on this page are derived from engineering data per NAAMM FP 1001-07 and ASCE 7-10. The Architect of Record or Engineer of Record is responsible for verifying that the specified flagpole meets all applicable local building codes and site-specific wind conditions, including ASCE 7-10 Special Wind Regions. Use the Cut Sheet Builder above to generate a detailed cut sheet for your configuration, or contact Flagpole Warehouse for assistance.
