20 Foot Above Grade Square Steel Light Pole | 4 Inches Wide | Direct Burial

Product Overview

This is a 20-foot above grade square steel light pole designed for direct burial installation. The total pole length is 25 feet, with 5 feet buried below grade to provide structural support without a concrete anchor base or bolt pattern.

The pole is 4 inches wide with an 11-gauge steel wall thickness. It weighs 167 pounds and includes a 2 3/8-inch tenon at the top for mounting fixtures or area lights.

The finish is hot dip galvanized and powder coated in bronze. This dual-layer finish provides corrosion resistance on the galvanized layer with a color-matched exterior coating.

Where This Product Fits Best

This pole is intended for applications where a 20-foot mounting height is appropriate and direct burial installation is preferred or required. Direct burial poles are commonly selected for parking lots, pathways, building perimeters, and other outdoor areas where anchor base installation is not practical or desired.

The 4-inch width and square profile suit single-fixture or small-area lighting configurations. The included 2 3/8-inch tenon accepts fixtures designed for that standard tenon size.

Performance and Functional Considerations

The Effective Projected Area ratings determine how much fixture load this pole can support at various wind speeds. At 90 mph wind, the pole supports up to 7.5 square feet of EPA. At 100 mph, the rating is 6.2 square feet. At 110 mph, 4.2 square feet. At 120 mph, 3.6 square feet. At 130 mph, 2.2 square feet.

When selecting fixtures, the combined EPA of all mounted equipment must fall within the rating for the expected wind conditions at the installation site. Fixture EPA values are typically listed in manufacturer specifications.

The 11-gauge steel wall provides structural rigidity for the 20-foot above-grade height. The 5-foot burial depth is engineered into the pole length and should be maintained during installation to achieve the rated wind load capacity.

Installation and Long-Term Use

This pole installs by direct burial into the ground. No anchor bolts, base plate, or concrete pier with embedded hardware is required. The buried section of the pole is set into an excavated hole and backfilled according to site soil conditions and local requirements.

The hot dip galvanized base layer protects the below-grade and above-grade steel from corrosion. The bronze powder coat finish provides the visible exterior color. Maintenance is limited to periodic inspection of the finish and tenon connection.

How This Fixture Is Commonly Used

Installers typically excavate a hole that accommodates the 5-foot buried length plus additional depth for compacted backfill or gravel base, depending on soil type. The pole is set plumb and secured before mounting fixtures to the tenon.

The 2 3/8-inch tenon at the top accepts slip-fit fixtures. Once the fixture is mounted and wiring is routed through the pole interior, the installation is complete. Future fixture replacement or maintenance involves accessing the tenon-mounted fixture without disturbing the pole.

Safety, Certifications, and Warranty

This pole carries a 1-year warranty.

The hot dip galvanized and powder coated finish is applied to the full pole length, including the buried section, to resist corrosion in ground contact and above-grade exposure.
