Product Overview
This is a 20 foot steel pole designed for commercial and industrial lighting applications. The pole has a 4 inch diameter and is constructed from 11 gauge steel.
The finish is hot dip galvanized with a powder coated bronze exterior. The pole is supplied with a top cap and is designed for anchor base installation.
Total pole weight is 143 lbs. The pole bolt circle is 8 inches, and bolt projection is 2.75 inches.
Where This Product Fits Best
This pole is suitable for mounting area lights, flood lights, or similar fixtures in parking lots, perimeter zones, and outdoor work areas where a 20 foot mounting height is required.
It is intended for use in environments where steel construction and a corrosion-resistant finish are needed for durability and appearance.
The anchor base design supports installation on concrete foundations or similar stable surfaces.
Performance and Functional Considerations
The pole is rated for effective projected area (EPA) loads at various wind speeds. At 70 mph, the EPA rating is 11.9. At 80 mph, the EPA rating is 9.1. At 90 mph, the EPA rating is 8.8. At 100 mph, the EPA rating is 6.8. At 110 mph, the EPA rating is 5.5. At 120 mph, the EPA rating is 3.8.
These EPA values define the maximum allowable surface area of fixtures and brackets that can be mounted at the top of the pole for each wind speed. Exceeding these values can compromise structural integrity.
The hot dip galvanized and powder coated finish provides resistance to corrosion and weathering in outdoor environments. The bronze color offers a neutral appearance suitable for most commercial sites.
The 11 gauge steel construction provides strength for supporting lighting fixtures within the specified EPA limits.
Installation and Long-Term Use
This pole is designed for anchor base installation. It requires a properly engineered concrete foundation and anchor bolt set compatible with the 8 inch bolt circle and 2.75 inch bolt projection.
The pole is supplied with a top cap to prevent water ingress during long-term outdoor use. The finish is intended to minimize maintenance requirements related to corrosion.
Routine inspection of mounting hardware and finish condition is recommended to ensure continued safe operation. The pole weight of 143 lbs should be considered when planning equipment and manpower for installation.
All mounting and installation work should follow applicable codes and site-specific engineering requirements.
How This Fixture Is Commonly Used
After installation, this pole provides a stable mounting point for area lighting or flood lighting at a 20 foot height. The anchor base allows for straightforward access to mounting hardware during maintenance or fixture replacement.
The galvanized and powder coated finish holds up against weather exposure, reducing the need for frequent touch-ups or repainting. The top cap keeps debris and moisture out of the pole interior.
Operators can mount fixtures and brackets within the EPA limits for their local wind conditions. The 4 inch diameter and 11 gauge wall thickness support typical commercial lighting loads when installed per specifications.
Day-to-day, the pole requires minimal interaction beyond periodic inspection of the finish and hardware. The bronze color blends with most site aesthetics and does not require special cleaning procedures.

This pole is constructed from steel and finished with hot dip galvanizing and powder coating for corrosion resistance.
LED Lighting Supply provides a 1 year warranty on this pole.
EPA ratings are provided for wind speeds from 70 mph to 120 mph to support safe application and installation planning.
