Wind Load Information

Pole Wind Loading:

Effective Projected Area or EPA is a wind resistance rating given for street fixtures, light pole brackets, and fixture accessories. The total of all accessory EPA ratings must not exceed the pole capacity EPA for the wind zone where it is installed (see wind zone map below).

Note that there may be more than one wind velocity in any geographical area (e.g., the greater Tampa, Florida area has three different wind zones). You should also select lighting poles for your location that can withstand the additional stresses caused by weight (the fixture, for example). Please check local ordinances and building codes for the most current requirements.*

Pole Banner Loading:

Note: the largest EPA addition to any pole will be from single or double rectangular shaped decorative banners and street signs. Why? The sign or banner's greater surface area is more exposed to the wind and creates a high EPA value when compared to fixtures and arm brackets. In this case, a larger pole diameter or thicker wall may be required. Always contact the manufacturer whenever banners are to be used.

Venia Lighting products are designed to meet industry accepted wind loading standards for decorative street lighting. State or federal lighting projects may require decorative poles to meet specifications established by the American Association of Street and Highway Traffic Officials (AASHTO). Consult the manufacturer for separate EPA capacities according to AASHTO recommendations.
