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

Product Overview

This is a 20 foot above grade round steel light pole with a 4 inch diameter, designed for direct burial installation. The total pole length is 25 feet, with 5 feet intended for burial below grade and 20 feet remaining above grade after installation.

The pole is constructed from 11 gauge steel and weighs 132 lbs. It is finished with hot dip galvanizing and a powder coated bronze color for corrosion resistance and durability.

A top cap is included with the pole. The direct burial design eliminates the need for anchor bolts or base plates during installation.

This pole is suited for supporting area lighting fixtures in commercial and industrial environments where direct burial is preferred.

Where This Product Fits Best

This pole is intended for outdoor lighting applications where a 20 foot mounting height is required above grade. Typical uses include parking lots, perimeter lighting, drive lanes, and general area illumination in commercial, industrial, or institutional settings.

The direct burial configuration is suitable for new construction or retrofit projects where excavation for below-grade installation is feasible. The 4 inch diameter and 11 gauge wall provide structural support for standard area and roadway lighting fixtures.

The hot dip galvanized and powder coated finish is appropriate for environments where exposure to weather, moisture, or corrosive elements is expected. The bronze color matches common site lighting aesthetics.

Performance and Functional Considerations

The pole?s EPA (Effective Projected Area) ratings define the maximum allowable fixture and bracket load at various wind speeds. At 70 mph, the EPA is 12.2; at 100 mph, the EPA is 7.2; and at 140 mph, the EPA is 1.0. These values must be considered when selecting fixtures and accessories to ensure structural integrity under site wind conditions.

The 4 inch diameter and 11 gauge steel construction provide a balance of strength and weight for most standard area lighting applications. The 132 lb weight should be factored into handling and installation planning.

The hot dip galvanized and powder coated finish provides resistance to corrosion and abrasion, supporting long-term durability in outdoor environments. The direct burial design requires proper backfill and compaction to maintain pole stability over time.

Installation and Long-Term Use

This pole is installed by direct burial, with 5 feet of the pole set below grade. Proper excavation, backfill, and compaction are required to achieve stable installation and prevent movement or leaning over time.

The included top cap protects the pole interior from moisture and debris. The hot dip galvanized and powder coated finish reduces maintenance requirements related to rust or surface degradation.

Routine inspection of the pole base and finish is recommended to identify any signs of corrosion or ground movement. The 1 year warranty from LED Lighting Supply covers material and manufacturing defects during the initial period of use.

How This Fixture Is Commonly Used

Once installed, this pole provides a 20 foot mounting height for area lighting fixtures. The direct burial design means there are no exposed base plates or anchor bolts at grade, reducing trip hazards and simplifying site cleanup.

The pole?s finish resists weathering, so routine cleaning is typically limited to removing surface dirt or debris. The top cap prevents water and pests from entering the pole, supporting long-term structural integrity.

Fixture mounting is accomplished at the top of the pole using standard brackets or tenons compatible with a 4 inch diameter. The EPA ratings guide the selection of fixtures and accessories to ensure the pole remains within safe wind load limits for the site.

Safety, Certifications, and Warranty

This pole is constructed from steel and finished with hot dip galvanizing and powder coating for corrosion resistance. The direct burial design requires proper installation to maintain safety and stability.

LED Lighting Supply provides a 1 year warranty covering material and manufacturing defects.
