What Is a Heavy Duty Flagpole?
A heavy duty flagpole is an aluminum pole built with thicker walls (.125"–.188"), larger butt diameters (4"–7"), and reinforced hardware to withstand sustained winds of 100–230+ mph. Unlike standard residential poles, heavy duty models use one-piece seamless construction or commercial-grade joints, allowing them to fly larger flags (5×8 ft and up) and survive hurricanes, coastal gusts, and long-term commercial use.
