20 Foot Round Steel Light Pole | 4.5 Inch Diameter | Anchor Base | Black

Product Overview

This 20 Foot Round Steel Light Pole is designed for outdoor area, parking lot, and roadway lighting applications where a durable, mid-height mounting structure is required. The pole is constructed from 11 gauge steel, hot dip galvanized and powder coated in black for corrosion resistance and long-term exterior use. Anchor base installation supports secure mounting to concrete foundations in commercial and industrial environments. A top cap is included for a finished appearance and to protect the pole interior from weather exposure.

This pole is commonly specified for new construction and retrofit projects where mounting heights around 20 feet are needed to achieve uniform site illumination. It is suitable for supporting a range of area, roadway, and parking lot luminaires within its EPA and weight limits.

Core Performance and Output

The 20 foot height and 4.5 inch diameter provide a balance between structural strength and visual scale for mid-sized exterior lighting layouts. The pole supports effective projected area (EPA) ratings up to 5.6 at 90 mph, with decreasing EPA capacity at higher wind speeds (1.1 at 140 mph). This allows for mounting of single or dual fixtures, depending on fixture size and local wind load requirements.

11 gauge steel construction delivers rigidity and vibration resistance for typical parking lot and roadway lighting heads. The anchor base design ensures stable installation on properly engineered concrete pads. Excessive fixture EPA or mounting multiple large heads may exceed wind load ratings, especially in high wind regions. Always verify fixture EPA and weight against the pole?s published limits for the intended site conditions.

Adjustability and Control Options

This pole is supplied with a top cap and anchor base hardware. It does not include a tenon; direct fixture mounting or custom tenon adapters may be required based on the luminaire type. The pole is compatible with standard area and roadway lighting heads designed for 4.5 inch round poles with anchor base mounting.

Fixture orientation and aiming are determined by the bracket or mounting hardware used with the selected luminaire. The pole itself does not provide integrated tilt or rotation adjustment. Control options such as photocells, motion sensors, or networked controls are determined by the fixture, not the pole.

Longevity and Reliability

Hot dip galvanizing provides a corrosion-resistant base layer, while the powder coated black finish offers additional protection against weathering and abrasion. This dual finish system is suitable for most commercial and industrial exterior environments, including areas with moderate exposure to road salts or urban pollutants.

The pole is designed for long-term structural reliability when installed according to manufacturer guidelines and within published EPA and weight limits. Routine inspection of anchor bolts and base hardware is recommended as part of ongoing site maintenance. The included 1 year warranty covers material and manufacturing defects.

Build Quality and Physical Characteristics

The pole is fabricated from 11 gauge steel, providing a robust structure for typical area and roadway lighting applications. The 4.5 inch diameter and 124 lb weight support stable installation and resistance to wind-induced vibration. The anchor base features a 7.25 inch bolt circle and 3.15 inch bolt projection, compatible with standard foundation designs.

All poles are supplied with a top cap to prevent water ingress and debris accumulation. The black powder coated finish delivers a uniform appearance and additional surface durability. Anchor bolts and base cover are included for a complete installation package.

Where This Product Fits Best

This 20 foot steel pole is suited for exterior lighting in commercial, municipal, and industrial environments where mid-height mounting is 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 pole?s finish and structural design are appropriate for outdoor use in most climates, including urban, suburban, and light industrial settings. Not intended for coastal or highly corrosive environments without additional protective measures.

Installation and Long-Term Use

Anchor base installation requires a properly engineered concrete foundation with correct bolt circle and projection. The pole is delivered with anchor bolts, base cover, and top cap for a complete installation. Luminaires can be mounted directly or with appropriate brackets or tenons as required by the fixture design.

Routine maintenance should include inspection of the base, anchor bolts, and finish condition. The hot dip galvanized and powder coated finish minimizes corrosion risk, but periodic cleaning and inspection are recommended for sites exposed to de-icing salts or industrial pollutants. The pole is not designed for direct burial or marine applications.

How This Fixture Is Commonly Used

20 foot steel poles are typically installed in parking lots, commercial sites, and along roadways to support area and roadway lighting heads. Standard mounting height is 20 feet from grade to fixture, providing effective coverage for medium-sized lots and site perimeters. Fixture spacing is determined by light distribution requirements and site geometry, with typical layouts ranging from 2 to 4 poles per row in parking lots or along drive lanes.

Using higher EPA fixtures or multiple heads per pole may require closer attention to wind load calculations. Reducing fixture count by increasing output per head can increase glare or reduce uniformity if not carefully planned.

Safety, Certifications, and Warranty

The pole is manufactured from structural steel and finished with hot dip galvanizing and powder coating for corrosion resistance. EPA ratings are provided for wind speeds from 90 to 140 mph. All hardware is included for anchor base installation. The product includes a 1 year warranty covering material and manufacturing defects. No additional certifications are stated.

Frequently Asked Questions

Q: What is the maximum fixture EPA this pole can support?

A: The maximum EPA is 5.6 at 90 mph, decreasing to 1.1 at 140 mph. Always verify fixture EPA and local wind speed requirements before installation.

Q: Does this pole include a tenon for fixture mounting?

A: No, a tenon is not included. Fixtures can be mounted directly or with a compatible tenon adapter if required.

Q: What type of foundation is required for anchor base installation?

A: A properly engineered concrete foundation with the correct bolt circle and projection is required. Refer to the anchor bolt specifications for layout details.

Q: Can this pole be used in coastal or marine environments?

A: The pole is hot dip galvanized and powder coated, but is not specifically rated for marine or highly corrosive environments.

Q: How should I plan fixture spacing and pole layout for a parking lot?

A: Fixture spacing and pole layout depend on light distribution, fixture output, and site geometry. Typical layouts use 2 to 4 poles per row, but always confirm with a photometric plan.

Application Questions and Clarification

Q: Is this pole suitable for supporting multiple fixtures?

A: Yes, as long as the combined EPA and weight of all fixtures do not exceed the pole?s published limits for the site wind speed.

Q: What is included with the pole for installation?

A: Anchor bolts, base cover, and top cap are included. No tenon is supplied.

Q: Can this pole be direct buried?

A: No, this model is designed for anchor base installation only and is not suitable for direct burial.

Q: What maintenance is required over time?

A: Periodic inspection of the base, anchor bolts, and finish is recommended, especially in areas exposed to de-icing salts or industrial pollutants.
