Special engineering may be required for other applications such as wall or roof mounted flagpoles. Please call, Email or fax for a prompt response regarding any situation that may require special engineering. Design of safe flagpoles requires knowledge of the loads of which they will be subjected. Principal load acting on flagpoles is wind load and that load must be carefully determined. Maximum wind speeds to which flagpoles are exposed depend on geographical location, whether or not it is in the center of a large city, a mall town's outskirts, seashore, at ground level or on the roof a high building.
Winds speeds generally are higher along coastal areas than inland.
They are also higher in open country than in the center of cities. Winds speed also becomes greater as height above ground increases. Wind exerts a force on the pole as well as the flag, thus both loads must be added to determine total load. Flags of different sizes are designed to be flown from different poles. Obviously, it is 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.
