Heavy-Duty Support for Exterior Gates

This in-ground aluminum alloy gate post provides a strong, stable foundation for composite and aluminum gate installations. Its heavy-duty construction is designed to manage the additional demands associated with swinging gates, making it suitable for both single and double gate configurations in residential and commercial settings.

Purpose-Built Dimensions and Material

The post has a nominal width of 4 inches, an actual width of 3.9 inches, and a height of 9 ft. It weighs approximately 21 lbs and is manufactured from Aluminum Alloy 6063 T5. Its design supports secure gate installation while maintaining a streamlined appearance suited to composite and aluminum fence systems.

Designed for Outdoor Conditions

Made for exterior use, the post is designed to resist rust, corrosion, moisture, UV exposure, high humidity, rain, and changing weather conditions. This makes it a practical structural component for outdoor entrances that require durable, stable gate support.

Residential and Commercial Applications

This gate post can be used for pedestrian gates, driveway gates, backyard entrances, garden entrances, side-yard access points, residential property entrances, privacy fence gates, multifamily properties, and commercial entrances.

In-Ground Installation

The post is installed directly into the ground to establish a secure foundation for the gate system. It is particularly appropriate for soil or dirt surfaces where an embedded post is required.
