20 Foot Square Steel Light Pole | 4 Inches Wide | Anchor Base

Product Overview

The 20 Foot Square Steel Light Pole with a 4-inch width and anchor base is designed for mounting area and roadway lighting fixtures in commercial and industrial environments. This pole is fabricated from 11-gauge steel, hot dip galvanized, and powder coated for long-term corrosion resistance. Typical installations include parking lots, commercial sites, and roadway perimeters where a 20-foot mounting height is required for optimal light distribution and coverage.

This pole includes a 2 3/8-inch tenon for direct fixture mounting and is available in bronze or white finishes. The anchor base design supports secure installation on concrete foundations, making it suitable for both new construction and retrofit projects where structural integrity and consistent appearance are priorities.

Core Performance and Output

This steel pole supports fixtures with EPA ratings up to 10.2 at 70 mph and 3.6 at 120 mph, allowing for a range of luminaire types and configurations. The 20-foot height is appropriate for standard parking lot and area lighting layouts, providing effective coverage without excessive glare or spill. The 4-inch square profile offers a balance of structural strength and visual uniformity for commercial sites.

Structural performance is maintained across a range of wind load conditions, but fixture selection must not exceed the EPA and weight limits at the site?s maximum wind speed. Excessive fixture size or mounting multiple luminaires per pole may require a lower EPA or alternate pole specification.

Adjustability and Control Options

The included 2 3/8-inch tenon accommodates standard slipfitter and direct-mount fixtures, supporting a variety of area, shoebox, and flood light heads. The pole?s square profile allows for single or multi-fixture mounting using compatible brackets or arms. No integrated electrical controls or wiring are included; fixture-level controls must be specified separately.

Orientation and aiming are determined by the fixture mounting hardware. The pole itself does not provide tilt or rotation adjustment beyond the capabilities of the attached luminaires and brackets.

Longevity and Reliability

The pole is constructed from 11-gauge steel and finished with hot dip galvanizing followed by a powder coat, providing resistance to corrosion and abrasion in outdoor environments. This finish is suitable for most commercial and industrial exterior applications, including areas exposed to de-icing salts or vehicle traffic.

Routine inspection of the pole, anchor bolts, and base plate is recommended to ensure long-term structural integrity. The finish and material selection are intended to minimize maintenance requirements under normal operating conditions.

Build Quality and Physical Characteristics

This pole measures 20 feet in total height, with a 4-inch square cross-section and a wall thickness of 11 gauge. The anchor base design features an 8-inch bolt circle and 2.75-inch bolt projection for secure mounting to concrete foundations. The pole weighs 169 lbs, providing substantial mass for stability and wind resistance.

Available in bronze or white powder coat finishes, the pole maintains a consistent appearance with most commercial lighting systems. The included tenon is compatible with standard area and roadway fixtures.

Where This Product Fits Best

This 20-foot steel pole is suited for exterior lighting in commercial and industrial environments where consistent mounting height and structural reliability are required. It is commonly used in:

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

The hot dip galvanized and powder coated finish provides durability in outdoor settings, including locations with exposure to weather, vehicle traffic, and moderate corrosive elements.

Installation and Long-Term Use

Installation requires a concrete foundation with anchor bolts set to the specified bolt circle and projection. The anchor base design allows for straightforward alignment and leveling during installation. The pole?s weight and dimensions require equipment for safe handling and placement.

Long-term use is supported by the corrosion-resistant finish and robust steel construction. Periodic inspection of the base, anchor bolts, and finish is recommended, especially in high-traffic or high-wind environments. The pole is designed for compatibility with standard area and roadway fixtures using the included tenon or optional mounting arms.

How This Fixture Is Commonly Used

Typical mounting height is 20 feet, supporting uniform light distribution for parking lots, roadways, and large commercial areas. Poles are spaced based on fixture output, site layout, and required light levels, with common spacing ranging from 2 to 4 times the mounting height depending on application and luminaire type.

Multiple poles are often deployed in grid or perimeter layouts to achieve consistent coverage. Using higher output fixtures can reduce the total number of poles but may increase glare or require careful aiming to control spill light.

Safety, Certifications, and Warranty

This steel pole is manufactured to meet structural and material standards for exterior lighting support. EPA ratings are provided for wind speeds from 70 mph to 120 mph. The hot dip galvanized and powder coated finish supports long-term outdoor use.

The product includes a 1-year warranty. No additional safety certifications are specified for this pole.

Frequently Asked Questions

Q: What is the maximum fixture EPA this pole can support at 100 mph wind speed?

A: The maximum EPA at 100 mph is 6.2.

Q: What type of foundation is required for installation?

A: A concrete foundation with anchor bolts matching the specified bolt circle and projection is required.

Q: Can this pole be used with both shoebox and flood light fixtures?

A: Yes, the included 2 3/8-inch tenon is compatible with standard shoebox and flood light slipfitter mounts.

Q: Is the pole suitable for coastal or high-corrosion environments?

A: The hot dip galvanized and powder coated finish provides corrosion resistance for most outdoor environments, but severe coastal or marine locations may require additional protection.

Q: How should I determine pole spacing for a parking lot?

A: Pole spacing depends on fixture output, site layout, and required light levels. Typical spacing is 2 to 4 times the mounting height.

Application Questions and Clarification

Q: Is this pole appropriate for sports facility lighting at a 20-foot mounting height?

A: Yes, this pole is commonly used for sports facility lighting where a 20-foot mounting height is suitable for the application and fixture EPA is within limits.

Q: Can this pole support multiple fixtures on a single tenon?

A: Multiple fixtures can be mounted if the combined EPA and weight do not exceed the pole?s rated limits for the site wind speed.

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

A: Periodic inspection of the pole, anchor bolts, and finish is recommended to ensure structural integrity and corrosion resistance.

Q: Are custom colors available for this pole?

A: This pole is available in bronze or white powder coat finishes only.
