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

Product Overview

This is an 18-foot steel square pole designed for direct burial installation, providing 15 feet of usable height above grade with 3 feet buried below grade. The pole measures 4 inches wide and is constructed from 11-gauge steel with a hot dip galvanized and powder coated bronze finish.

The pole weighs 121 pounds and includes a 2 3/8 inch tenon for fixture mounting. This configuration is built specifically for direct burial applications where an anchor base system is not required or preferred.

Where This Product Fits Best

This pole is suited for applications where a 15-foot mounting height meets the project requirements and direct burial installation is the preferred method. The 4-inch square profile and bronze finish work in parking areas, pathways, building perimeters, and similar outdoor lighting applications where a mid-height pole is appropriate.

Direct burial poles are commonly selected for sites where anchor bolt foundations are impractical or where installation simplicity is a priority. The 3-foot burial depth should be verified against local frost line requirements and site soil conditions before specifying.

Performance and Functional Considerations

The EPA ratings define the maximum fixture area this pole can support at various wind speeds. At 90 mph, the pole supports fixtures with up to 11.1 square feet of effective projected area. At 110 mph, that value drops to 7.9 square feet, and at 130 mph, the maximum is 5.2 square feet.

When selecting fixtures, the combined EPA of all mounted luminaires must fall within the rated capacity for the site''s design wind speed. This is a structural constraint and must be confirmed during project specification.

The 11-gauge steel construction and galvanized plus powder coated finish provide corrosion resistance suited for outdoor exposure. The bronze color is applied over the galvanized layer.

Installation and Long-Term Use

Installation requires excavating to accommodate the 3-foot burial depth plus any additional depth needed for drainage or compacted backfill. The pole is set directly into the ground and backfilled, eliminating the need for a separate concrete foundation with embedded anchor bolts.

The 2 3/8 inch tenon accepts fixtures designed for that standard tenon size. Confirm fixture compatibility before installation. Once installed, the pole requires no routine adjustment, though periodic inspection of the finish and base condition is standard practice for outdoor steel structures.

How This Fixture Is Commonly Used

This pole is typically installed in areas where 15 feet of above-grade height is appropriate for the lighting layout. The 2 3/8 inch tenon allows mounting of area lights, flood lights, or decorative fixtures that accept a standard slip-fitter or tenon adapter.

For sites with multiple poles, the bronze finish provides visual consistency with architectural or landscape elements. The direct burial method reduces installation complexity compared to anchor base systems, particularly on smaller projects or in locations where concrete work is difficult to coordinate.

Safety, Certifications, and Warranty

This pole is covered by a 1-year warranty. The hot dip galvanized and powder coated finish is applied to resist corrosion from weather exposure.

Structural performance is defined by the EPA ratings provided. Final installation must comply with local building codes, wind load requirements, and soil conditions at the site.
