20 Foot Above Grade Round Steel Light Pole | 4 Inch Diameter | Direct Burial

Product Overview

This 20-foot above grade round steel light pole is built for direct burial installation, eliminating the need for a concrete foundation or anchor base. The total pole length is 25 feet, with 5 feet designed to be set below grade. The 4-inch diameter shaft is constructed from 11-gauge steel with a hot dip galvanized and powder coated bronze finish.

The pole ships with a top cap included. Total weight is 132 pounds. This configuration is intended for parking lots, pathways, and perimeter lighting applications where a straightforward buried installation method is preferred over anchor base mounting.

Where This Product Fits Best

This pole is sized for applications requiring a 20-foot mounting height with moderate fixture loads. The 4-inch diameter and 11-gauge wall thickness establish the structural capacity, which is defined by the EPA ratings at various wind speeds. At 90 mph wind, the pole supports fixtures with a combined EPA up to 8.8 square feet. At 130 mph, that capacity drops to 2.2 square feet.

Direct burial poles are commonly selected for sites where pouring a concrete foundation is impractical or where faster installation is needed. The bronze powder coat finish suits applications where aesthetic consistency with surrounding architecture or landscaping matters.

Performance and Functional Considerations

EPA ratings determine how much wind-loaded fixture area the pole can safely support at a given wind speed. Before selecting fixtures, calculate the combined EPA of all luminaires, arms, and accessories intended for the pole, then confirm that total falls within the rating for your site''s design wind speed.

The dual-layer finish?hot dip galvanizing under powder coat?provides corrosion resistance for the buried and exposed sections. The galvanized layer protects the steel where it contacts soil, while the powder coat maintains appearance above grade.

Installation and Long-Term Use

Direct burial installation requires excavating a hole to accept the 5-foot below-grade section, setting the pole plumb, and backfilling with appropriate material per local soil conditions and code requirements. No anchor bolts, base covers, or foundation hardware are involved. Conduit entry is made through the handhole or base of the pole depending on site wiring methods.

At 132 pounds, the pole can typically be handled and set by a small crew with standard equipment. The included top cap seals the shaft opening. Long-term maintenance is limited to periodic inspection of the finish and hardware connections at the fixture mounting point.

How This Fixture Is Commonly Used

Once installed, this pole serves as a fixed mounting point for area lights, flood lights, or decorative fixtures at a 20-foot height. Fixture arms or tenon-mount luminaires attach at the top of the shaft. The bronze finish blends with common commercial and institutional color palettes, reducing visual contrast in landscaped or architectural settings.

Operators and maintenance personnel access the pole wiring through the handhole for conductor terminations and troubleshooting. The 4-inch diameter accepts standard tenon-mount hardware without adapters in most configurations.

Safety, Certifications, and Warranty

This pole is covered by a 1-year warranty. The EPA ratings listed define the maximum allowable fixture area at specified wind speeds and should be used to verify structural suitability for the intended installation site and local wind load requirements.
