25 ft heavy-duty commercial flagpole with a 5" butt and 0.188" wall, made in the USA from 6063-T6 aluminum. Wind-rated to 232 MPH without flag, it's our highest-spec 25-footer — built for coastal exposure, high-wind zones, and sites that need maximum strength without going up in pole diameter. Complete kit ships with a gold or silver ball ornament, revolving truck, halyard, vinyl-covered flag snaps, cleat, flash collar, and ground sleeve. Recommended flag: 5' x 8'. Available in Satin, Clear Anodized, Bronze Anodized, and Black Anodized finishes.
25 ft Heavy-Duty Commercial Flagpole (5-inch Butt)
There are three situations where the 5-inch, 0.188-inch-wall Heavy Duty 25-footer is the only pole that makes sense, and the thinner-wall Standard (0.156") or Economy (0.125") will eventually fail you. First: any coastal site within 20 miles of the Atlantic, Gulf, or Pacific where Category 1+ hurricane risk is real — the 0.188-inch wall changes the failure mode from 'bent and replaced' to 'still standing.' Second: civic and institutional sites that fly the flag 24/7 with illumination, where structural inspection liability sits with the property owner. Third: dealerships, hotels, and visitor-facing properties that want to fly a 5×8 ft flag in exposed conditions without the pole visibly oscillating in afternoon wind.
Stamped engineering letters for permitting are available within a week as a paid add-on. Freight delivery is included to commercial docks; for non-dock sites, add lift-gate service. Lead time is typically 3–4 weeks from order to delivery.
When to Choose the 5-inch Heavy-Duty Over the Standard 4-inch
- •Coastal sites within 20 miles of the Atlantic, Gulf, or Pacific
- •Properties in hurricane-prone counties (FL, NC, SC, TX, LA, MS, AL)
- •Sites flying a 6×10 ft or larger flag year-round
- •Civic buildings, fire stations, and police HQs flying 24/7 with illumination
- •Auto dealerships and visitor-facing retail with high foot traffic and liability exposure
- •Any site where the local design wind speed (ASCE 7) exceeds 130 MPH
Installation Notes for the Heavy-Duty 25
The heavier wall and larger butt mean a heavier pole (~95 lbs) and a more substantial footing than the standard 25 ft commercial. Plan for a 2-person crew with equipment.
- Excavate a 54" deep × 18" diameter footing (deeper in zones 5+ to clear the frost line)
- 4–6" of #57 gravel for drainage at the bottom of the hole
- 18" sonotube form, with an 18" steel ground sleeve centered and plumbed on two axes
- Pour 10–14 bags of high-strength concrete in 12" lifts; do NOT use quick-set
- Cure a minimum of 7 days before raising the pole — full strength at 28 days
- Two-person lift to seat the pole into the sleeve; secure with stainless wedges and reeve the external halyard
For sites in Florida and the Gulf Coast, request the hurricane-rated installation drawing — it specifies a deeper bell-shaped footing and rebar cage for Category 3 design loads.

Frequently Asked Questions
What makes this "heavy-duty" vs. the standard 25 ft commercial pole?
The butt diameter is the same 5 inches; the wall thickness steps up from 0.156" (Standard) to 0.188" (3/16") on Heavy Duty. That extra material is what changes the rated wind speed with a 5×8 ft flag from 110 MPH to 140 MPH per the engineered spec sheet.
Is this pole hurricane-rated?
Rated for a 5×8 ft flag at 140 MPH in ASCE 7 Exposure Category C, which covers Category 4 sustained wind. For permit submission in hurricane zones, request the engineered footing detail — deeper bell-shaped footing with rebar cage — which lets the entire assembly meet Florida Building Code high-velocity hurricane zone (HVHZ) requirements.
Can I install this myself?
You can dig the footing yourself, but raising the pole onto a 25 ft sleeve really requires two adults and a third person on a tag line. Most owners hire a local installer for the lift even if they did the dig and pour themselves.
What size flag should I fly?
A 5×8 ft flag is the engineered rating on this pole. The 0.188" wall gives real headroom against gusts and long-duration high winds compared to the Standard. Larger flag sizes should be reviewed against a site-specific wind-load calc before ordering.
Do I need stamped drawings for my permit?
Most jurisdictions require stamped drawings for any commercial flagpole over 20 ft. We provide them within 5–7 business days for an additional fee — send your address and AHJ name when ordering to get a quote.
How does this ship?
Freight to a commercial dock is included. The pole ships in a single 25 ft crate; freight typically transits in 5–10 business days after the order builds. Add lift-gate service at checkout if your site does not have a forklift.
Who This Flagpole Is For
Not sure if this is the right pole for you? Here's who it's built for.
Businesses & Municipalities
Office parks, government buildings, schools, dealerships, and HOAs that need a long-lasting, professional display.
Estate Homes & Large Properties
Homeowners who want a heavier, taller pole — typically 25 ft or larger — that stands out and lasts decades.
Installers & Contractors
Pros installing for clients who need reliable lead times, predictable specs, and a 5-year shaft warranty.
This Pole's Specs
Manufacturer-tested wind rating and recommended flag size for this exact model. Sizing your flag correctly keeps the pole within its rated wind speed. See the full sizing guide →
Wind rating reflects manufacturer-tested performance for the flagpole without a flag installed. Flying a flag — especially one larger than recommended — reduces the effective wind rating.
How Installation Works
Commercial-grade flagpoles are a more involved install than residential. The pole has to be carefully plumbed and the ground sleeve packed with sand for proper load handling. We recommend professional installation; in Central Ohio we install them ourselves.
It Arrives Ready to Install
In-stock flagpoles ship to 48 states. You receive the pole, ground sleeve, hardware, and instructions.
Set the Ground Sleeve
Dig the foundation per the included spec, set the steel ground sleeve, plumb it true, and pour concrete around it. Let the concrete cure 24–48 hours before installing the pole.
Set the Pole, Pack & Fly
Lower the pole into the cured sleeve and plumb it true. Pack clean, dry sand around the pole inside the sleeve to lock it in and absorb wind load. Attach your halyard and flag and raise it. A 25 ft+ commercial pole typically needs 2–3 people or a small lift.
Local Installation Available in Central Ohio
We professionally install flagpoles in Columbus, Lancaster, Pickerington, Canal Winchester, and surrounding suburbs — backed by 25 years and hundreds of installs.
