The selection of the correct pole design is predicated on the specifi c loading requirements of each application. The poles located in the steel pole chart are designed to withstand dead loads and theoretical dynamic loads developed by sustained winds of 80 MPH through 110 MPH times the 1.3 gust factor. The combined EPA and the weight of the luminaire, light support brackets, platforms and any other attachments cannot exceed the rated EPA or allowable weight of that pole.
All welds shall be of the highest quality and performed by American Welding Society certifi ed welders conforming to the latest version of the American Welding Society specifi cation AWS D1.1.
All poles, mounting brackets and platforms are furnished with a coating of either red oxide/zinc primer, factory painted, powder coated or hot-dip galvanized to ASTM A-123. Miscellaneous hardware will be galvanized to ASTM A-153. Exterior fi nish coatings are available by request.
The steel pole shall consist of the appropriate number of pole sections, either round or multi-sided, for heights up to 120 feet. Each section shall be fabricated from high strength low alloy steel conforming to ASTM A-572, with a minimum yield strength of 55,000 psi. These shafts shall telescope over each other to match the overall desired pole height. The overlap telescoping joint shall have a length that is the larger of 2 feet or 1-1/2 times the diameter of the inside of the female tube. The sections shall be pre-fi tted and match marked at the factory. All sections shall maintain a uniform taper from top to bottom. There shall be at least one longitudinal seam weld in the tapered section of the shaft. The longitudinal seam weld shall have at least 60% penetration, except in the areas where the shaft section telescopes over another. In overlapping areas, the weld penetration shall be 100%. No circumferential weld splices may be used in fabricating the shafts. Base Plate
The base plate is fabricated from a structural quality hot rolled carbon steel plate that meets or exceeds ASTM A-36 with a minimum yield of strength of 42,000 psi. The base plate shall telescope the pole shaft and have a circumferential weld on the top and bottom or shall have a full penetration butt weld with a back up bar. The anchor bolt holes shall be slotted and will be a minimum 1/4” larger than the diameter of the anchor bolts used on the pole.
An oval reinforced hand hole, having a nominal 4” x 6” x .25” wall, will be installed 18” above the base plate. A hand hole cover and attaching hardware is included with each hand hole assembly. A ground lug will be welded inside the pole opposite the hand hole. This is standard on all poles unless otherwise specifi ed. Anchor Bolts Anchor bolts are fabricated from a commercial quality hot-rolled carbon steel bar that meets or exceeds minimum yield strength of 55,000 psi. Anchor bolts
are sized according to each pole design and are furnished with 2 galvanized heavy hex nuts and 2 galvanized fl at washers. Anchor bolts shall be galvanized a minimum of 6 inches on the threaded end in accordance with ASTM A-153. Anchor bolts will ship with the poles unless otherwise noted.
Each pole will be provided with either a removable pole cap, fl at plate, or 2 3/8” O.D. x 5” tenon top (other sizes available).
