Summary

The last fence post you'll ever set: welded-aluminum in-ground posts in matte black, 4"x4" and 5"x5". They can't rot like wood or rust like steel — set them in concrete once and forget them. Run our aluminum or steel privacy panels, or use them to replace the rotted 4x4 under an existing wood fence and keep your boards. Three lengths (6', 9', 12') matched to our steel post grid, with extra below-grade length on the taller posts. Made in Canada, delivered and unloaded on your property and unloaded.

Description

The last fence post you'll ever set. Welded-aluminum in-ground fence posts in matte black, in 4" x 4" and 5" x 5" profiles. They can't rot like wood and can't rust like steel — set them in concrete once and forget them.

One Post, Two Jobs

Run our aluminum or steel panels — the post system carries our privacy fence panels for a complete zero-rust build.
Replace rotted wood posts under an existing wood fence — keep your boards, swap the failure point. Aluminum posts are the permanent fix for the 4x4 that keeps rotting off at grade.

Never Dig Out a Rotted Post Again

Wood posts fail where they meet the ground. Aluminum has no grain to wick water and nothing to rot — the below-grade section is as permanent as the concrete around it. The 9' and 12' lengths carry extra below-grade length for taller fence runs.

Sizing — Same Grid as Our Steel Posts

Two profiles and three lengths, matching our steel fence post grid exactly: choose 4" x 4" for standard fence lines, or 5" x 5" for gate posts and heavier-duty runs. 6' posts for low runs and rail work, 9' for standard privacy heights, 12' for 8' privacy fencing.

On-Property Delivery & Unload — Western Canada

Made in Canada and delivered on our own trucks: your order arrives at your property and our crew unloads it. Check your postal code in the shipping estimator for your current delivery window.

Frequently Asked Questions

Aluminum vs steel fence posts?

Both outlast wood by decades. Aluminum adds zero-rust for life and lighter handling; steel offers maximum stiffness for the heaviest gate posts. For most fence lines, aluminum is the set-and-forget option.

What post spacing should I use?

6' or 8' on-center, matching our panel widths.

Do I need rot protection sleeves on these?

No — sleeves protect wood posts. Aluminum needs nothing below grade. (If you're keeping wood posts elsewhere on the run, see our Post Rot Protection System.)

🏅 Warranty

BarrierBoss 25-year limited structural warranty on the welded 6063-T5 aluminum — aluminum cannot rust, including at cut edges. 15-year limited warranty on the factory matte black finish (peeling, flaking; gradual gloss reduction from weathering is normal, not a defect). Structural modifications beyond normal installation void the warranty. Installation quality is the installer's responsibility — improper installation is not covered.
