25 Foot Round Steel Light Pole | 4 Inch Diameter | Anchor Base

Product Overview

This 25 foot round steel light pole provides a fixed-height mounting structure for area lighting fixtures in parking lots, pathways, building perimeters, and similar outdoor applications. The pole is constructed from 11-gauge steel with a 4 inch diameter and uses an anchor base mounting system that secures to a concrete foundation with embedded anchor bolts.

The pole arrives with a hot dip galvanized and powder coated bronze finish applied over the steel substrate. This dual-layer finish process addresses both corrosion resistance and color consistency. A top cap is included to seal the pole opening against water and debris intrusion.

Total pole weight is 139 lbs. The anchor base bolt circle accommodates 8 to 10 inch patterns, and bolt projection is 2.75 inches from the base plate surface.

Where This Product Fits Best

This pole height and construction are appropriate for commercial parking areas, retail lot perimeters, industrial yard lighting, campus pathways, and building entrance approaches where fixtures need to clear vehicles and pedestrian traffic while distributing light across open areas.

The bronze powder coat finish suits applications where color coordination with building exteriors or site furniture is required. Hot dip galvanizing beneath the powder coat provides base-level corrosion protection in humid, coastal, or chemically exposed environments.

Performance and Functional Considerations

Wind load capacity is expressed as Effective Projected Area ratings across standard wind speed thresholds. At 70 mph, the pole supports fixtures and mounting hardware with a combined EPA up to 11.8 square feet. At 90 mph, that drops to 7.7 square feet. At 120 mph, the maximum supported EPA is 4.2 square feet.

These ratings determine which fixture combinations can be mounted without exceeding the structural limits of the pole. Fixture manufacturers publish EPA values for their products, and total EPA of all mounted components must fall within the pole rating for the site''s design wind speed.

The 4 inch diameter and 11-gauge wall thickness establish the pole''s structural baseline. Installers should verify that tenon adapters, slip fitters, or arm mounts intended for use with the pole are compatible with this diameter.

Installation and Long-Term Use

Anchor base installation requires a poured concrete foundation with embedded anchor bolts positioned to match the 8 to 10 inch bolt circle. The pole base plate drops over the bolts and is secured with nuts and washers. Bolt projection of 2.75 inches determines the required thread engagement and hardware stack-up above the base plate.

Wiring is routed through a handhole or base access point and up through the interior of the pole. The top cap keeps moisture and debris from entering the pole cavity. Periodic inspection of the base hardware and finish condition is standard practice for poles in outdoor service.

How This Fixture Is Commonly Used

Once installed, the pole functions as a permanent mounting point for area lights, flood lights, or decorative fixtures. Facility operators typically mount fixtures using slip fitters or tenon adapters sized for the pole top diameter or add horizontal arms to support multiple fixtures from a single pole.

The bronze finish holds up to sun exposure and weather without frequent refinishing. If the finish is scratched or chipped during installation, touch-up paint matched to the powder coat color can be applied to prevent corrosion at the exposed steel.

Safety, Certifications, and Warranty

This pole is covered by a 1 year warranty. The hot dip galvanized and powder coated finish is included in that coverage under normal use conditions.

Structural integrity depends on proper foundation design, correct anchor bolt installation, and adherence to the EPA limits for the applicable wind speed zone. Foundation engineering and local code compliance are the responsibility of the installer or specifying engineer.
