20 Foot Above Grade | 25 Foot Total Height Round Steel Light Pole | 4 Inch Diameter | Direct Burial

Product Overview

This is a 25-foot total height, 4-inch diameter round steel light pole designed for direct burial installation. The pole provides 20 feet of height above grade, with 5 feet set below ground for structural stability. Typical use includes supporting area, parking lot, and roadway lighting fixtures in commercial and industrial environments where a robust, corrosion-resistant steel pole is required.

The pole is constructed from 11-gauge steel, hot dip galvanized and powder coated in bronze for long-term durability. It is supplied with a top cap and is engineered for direct burial applications, eliminating the need for anchor bolts or base plates. This configuration is commonly specified for new site lighting installations or pole replacement projects where concrete foundations are not desired.

Core Performance and Output

This pole supports a range of area and roadway lighting fixtures, with EPA (Effective Projected Area) ratings from 12.2 at 70 mph to 1.0 at 140 mph. The 4-inch diameter and 11-gauge wall thickness provide structural capacity for typical single or dual fixture mounting at 20 feet above grade. The direct burial design delivers reliable wind load performance when installed to recommended depth and compaction standards.

EPA and weight limits must be observed to prevent pole deflection or failure, especially in regions with high wind exposure. Excessive fixture weight or EPA at the top of the pole will reduce wind load capacity and may require a larger diameter or heavier gauge pole. Consult EPA tables for fixture and bracket combinations before installation.

Adjustability and Control Options

This pole is compatible with standard tenon or side-mount brackets for area, parking lot, and roadway fixtures. Fixture orientation and aiming are determined by the selected mounting hardware, not by the pole itself. The pole does not include integrated control options or wiring provisions; conduit and wiring must be field-installed according to site requirements.

Direct burial installation allows for some rotational adjustment during setting, but final fixture alignment depends on bracket selection and field installation practices.

Longevity and Reliability

The pole is hot dip galvanized and powder coated for corrosion resistance in outdoor environments. This finish combination provides protection against rust and surface degradation from weather exposure, road salts, and routine site maintenance activities. The steel construction offers long-term structural reliability when installed to proper burial depth and compaction standards.

Routine inspection of the above-grade finish and below-grade interface is recommended to monitor for signs of corrosion or mechanical damage over time. The pole is covered by a 1-year warranty.

Build Quality and Physical Characteristics

Constructed from 11-gauge steel, the pole weighs 132 lbs and features a 4-inch outside diameter. The hot dip galvanized and powder coated bronze finish is standard for commercial exterior applications. The pole is supplied with a top cap to prevent water ingress and debris accumulation.

Direct burial installation requires a 5-foot embedment below grade. The pole is designed for use in soil conditions suitable for direct burial steel and should not be installed in corrosive or high-salinity soils without additional protection.

Where This Product Fits Best

This pole is intended for outdoor site lighting in commercial and industrial environments where direct burial installation is preferred. It is suitable for supporting area, parking lot, and roadway fixtures at standard mounting heights. The EPA ratings and 4-inch diameter make it appropriate for single or dual fixture mounting in moderate wind zones.

• parking lot lighting
• roadway lighting
• area lighting
• commercial site lighting
• sports facility lighting
• campus lighting
• industrial yard lighting
• dealership lighting

The galvanized and powder coated finish supports long-term use in typical outdoor environments. Not recommended for marine, coastal, or highly corrosive soil conditions without additional protective measures.

Installation and Long-Term Use

Direct burial installation requires excavation to a minimum 5-foot depth, with proper backfill and compaction to ensure stability. The pole should be set plumb and aligned before final backfill. Wiring is typically routed through conduit installed alongside the pole during burial.

Routine maintenance includes inspection of the finish, checking for corrosion at the ground line, and verifying fixture mounting hardware integrity. Replacement or repair of the pole may be required if significant corrosion or structural damage is observed over time.

How This Fixture Is Commonly Used

Commonly installed at 20 feet above grade, this pole supports area and roadway fixtures for uniform site illumination. Typical layouts use single or dual fixtures per pole, spaced according to site lighting requirements and fixture output. Poles are often arranged in rows or perimeters for parking lots, drive lanes, or site boundaries.

Fixture spacing and pole count are determined by required light levels, fixture wattage, and site geometry. Higher EPA fixtures or multiple fixtures per pole may require reduced pole spacing or larger diameter poles to maintain wind load compliance.

Safety, Certifications, and Warranty

The pole is manufactured from structural steel and finished with hot dip galvanizing and powder coating. EPA ratings are provided for wind speeds from 70 mph to 140 mph. The pole includes a 1-year warranty.

All installation and use must comply with local codes and standards for structural supports and site lighting. No additional certifications are specified for this product.

Frequently Asked Questions

Q: What is the maximum EPA this pole can support at 20 feet above grade?

A: The maximum EPA is 12.2 at 70 mph, decreasing to 1.0 at 140 mph. Refer to the EPA table for specific wind speed requirements.

Q: Can this pole be used for dual fixture mounting?

A: Yes, provided the combined EPA and weight of fixtures and brackets do not exceed the pole?s rated limits for the site wind speed.

Q: Is this pole suitable for coastal or marine environments?

A: This pole is not recommended for marine or highly corrosive environments without additional protective measures.

Q: What is the required burial depth for installation?

A: The pole requires a 5-foot burial depth below grade for proper structural support.

Q: How should wiring be routed for this pole?

A: Wiring is typically installed in conduit alongside the pole during burial, with access provided at the top for fixture connection.

Q: How do I determine the correct pole spacing for a parking lot?

A: Pole spacing depends on fixture output, site geometry, and required light levels. Consult a photometric layout for optimal results.

Application Questions and Clarification

Q: Can this pole be used for sports facility lighting?

A: Yes, within the EPA and mounting height limits, this pole is suitable for supporting sports facility lighting fixtures.

Q: Is this pole compatible with all area and parking lot fixtures?

A: The pole supports fixtures compatible with a 4-inch diameter mounting and within the EPA and weight limits specified.

Q: What maintenance is required for long-term use?

A: Periodic inspection of the finish, ground line, and fixture mounting hardware is recommended to ensure structural integrity and corrosion resistance.
