Product Overview
This 20 Foot Round Steel Light Pole is designed for exterior area and roadway lighting applications where structural integrity and long-term durability are required. The pole stands 20 feet tall with a 4-inch diameter and is fabricated from 11 gauge steel. It features a hot dip galvanized and powder coated finish for corrosion resistance in outdoor environments. Anchor base installation is standard, supporting secure mounting to concrete foundations in parking lots, commercial sites, and along roadways.
The pole includes a top cap and is finished in bronze. It is engineered to support area and site lighting fixtures within specified EPA and wind load limits. This pole is commonly used for mounting LED shoebox, area, or roadway luminaires at heights suitable for parking lot and commercial site illumination.
Core Performance and Output
This steel pole is rated for EPA loads up to 11.9 at 70 mph and 3.8 at 120 mph, supporting a range of single or multiple fixture configurations depending on local wind conditions. The 4-inch diameter and 11 gauge wall thickness provide structural stability for mounting area and roadway luminaires at 20 feet. The anchor base design allows for straightforward installation and secure attachment to standard bolt patterns.
Performance is dependent on fixture EPA and total weight. Exceeding EPA ratings at higher wind speeds can compromise structural safety. For sites with frequent high winds or oversized fixtures, verify total EPA and weight before installation.
Adjustability and Control Options
This pole is non-tapered and does not include integrated tilt or aiming adjustments. Fixture orientation and control depend on the mounting hardware and bracketry used with the selected luminaires. The anchor base allows for rotational alignment during installation before final bolt tightening.
Control options such as photocells, motion sensors, or networked controls are determined by the fixtures mounted to the pole, not by the pole itself.
Longevity and Reliability
The pole is constructed from 11 gauge steel and finished with hot dip galvanizing followed by a powder coat, providing resistance to corrosion and weathering in outdoor environments. The finish is suitable for standard commercial and municipal exterior use. The included top cap prevents water ingress and internal corrosion at the pole top.
Routine inspection of the finish and anchor hardware is recommended to maintain long-term reliability, especially in areas with deicing salts or industrial pollutants. The pole is covered by a 1 year warranty.
Build Quality and Physical Characteristics
This pole measures 20 feet in total height with a 4-inch round cross-section and weighs 143 lbs. The 8-inch bolt circle and 2.75-inch bolt projection are compatible with standard anchor base foundations. The steel construction provides rigidity for area and roadway lighting applications.
The bronze powder coated finish over hot dip galvanizing offers a durable, low-maintenance exterior. The pole is supplied with a top cap and is designed for upright mounting only. No handhole is included in this model.
Where This Product Fits Best
This 20 foot steel pole is suited for exterior lighting in commercial, municipal, and industrial environments where 20 foot mounting heights are standard. It is commonly used for parking lot, roadway, and area lighting with compatible fixtures. The pole is also specified for dealership and campus site lighting where uniformity and structural reliability are required.

The finish and construction are suitable for standard outdoor environments. For coastal or highly corrosive sites, additional protective measures may be required.
Installation and Long-Term Use
Anchor base installation requires a properly sized concrete foundation with embedded anchor bolts matching the 8-inch bolt circle. The pole is set over the bolts, leveled, and secured with nuts and washers. Fixture mounting is completed after the pole is plumb and fully torqued.
Routine maintenance includes inspection of the finish, anchor hardware, and fixture mounting points. For sites with snow plowing or heavy vehicle traffic, ensure pole placement avoids impact risk. The pole is not designed for direct burial or for use in marine or high-salinity environments without additional protection.
How This Fixture Is Commonly Used
Poles of this height are typically installed at 20 foot mounting heights for parking lot and area lighting layouts. Spacing between poles varies based on fixture output, beam distribution, and site requirements, but 2 to 4 times the mounting height is common for uniform coverage. Multiple fixtures can be mounted per pole if total EPA and weight limits are observed.
Higher EPA fixtures or multi-head configurations may require closer pole spacing or reduced mounting height to maintain structural safety. Using lower EPA fixtures allows for greater flexibility in layout and fixture selection.
Safety, Certifications, and Warranty
This pole is fabricated from structural steel and finished with hot dip galvanizing and powder coating. EPA ratings are provided for wind speeds from 70 mph to 120 mph. The pole includes a 1 year warranty. No additional safety certifications are specified for this model.
Installation must comply with local codes and engineering requirements for wind load and foundation design. Always verify fixture EPA and weight before installation to ensure compliance with published ratings.
