Aluminum Fence Post Systems for Structural Performance and Installation Flexibility

SLEEKFENCE post systems are engineered to support a range of installation conditions while maintaining structural integrity, precise alignment, and a consistent architectural expression across the system. Designed as an integral component of the overall fence assembly, each configuration ensures reliable performance across varying site and project requirements.

Post Profiles

Post profiles are selected based on structural requirements, fence height, and application conditions.

3" × 3" aluminum posts
Designed for lighter applications, supporting fence heights up to 6 ft.

4" × 4" aluminum posts
Standard profile suitable for most applications, supporting fence heights up to 12 ft.

6" × 6" aluminum posts
Heavy-duty profile for large gate systems and higher load conditions.

Installation Systems

Post systems are designed to accommodate a range of installation conditions, from embedded foundations to surface-mounted applications.


Embedded Systems

Embedded systems are designed for maximum structural performance, with posts set directly into concrete footings to provide long-term stability and alignment.

Dig & Set (Embedded)
Posts are embedded directly into concrete footings to provide maximum strength and long-term structural performance, typically used for fence heights up to 8 ft. This method does not require internal inserts and is suited for standard applications.

Overheight System (Embedded)
Designed for fence heights up to 12 ft, this system utilizes an engineered insert sleeved within the aluminum post, combined with a precision shim system to ensure a secure and fully integrated structural connection under increased load conditions.

Surface Mount Systems

Surface-mounted systems are designed for installation on existing slabs or structural surfaces, providing flexibility where in-ground installation is not feasible.

Light Duty Surface Mount
Aluminum posts are mounted using a pre-welded baseplate, suitable for lower fence heights and reduced wind load conditions. An aluminum skirt conceals anchors while maintaining a clean architectural appearance.

Heavy Duty Surface Mount
Engineered for higher wind exposures, rooftop applications, and overheight systems, this configuration uses reinforced baseplates and a sleeved internal post system with precision shimming to ensure structural stability. Multiple baseplate sizes are available depending on project requirements.
