Gates put more load on their posts than any other part of a fence. The 4×4 in. x 8ft. HD Square Post (.125 Thk) from Aluglobus Aluminum Systems is a 4×4 aluminum gate post 8 ft long, with a .125 wall thickness, the heaviest wall among the square posts in our price list. It is listed for pedestrian gates and sliding gates.
In the pedestrian gate post options, this post appears as the concrete footing option: Option 5 Concrete Footing – 4×4 in. x 8ft. HD Square Post (.125 Thk). The heavy-duty sliding gate kits also list a 4 in. square post for concrete footing as one of their two post options, alongside a 3 in. post. That makes the 4×4 in. post the choice when you want a free-standing gate post set in concrete rather than a wall-mounted one. Explore compatible gates in our aluminum gates range, including the DIY sliding gate 19 ft x 6 ft.
The same 4×4 in. HD post is listed in three lengths:
Work out how much post you need above grade for your gate height and hardware, then add the depth your footing requires. If 8 ft covers both, it is the easiest length to handle and set; if not, step up to 11 ft or 12 ft. Footing size and depth should follow the included instructions and your local code, and our team can confirm the right length for your gate.
Close the top of the post with the 4" flat press cap, which is listed for 4 in. square posts. Hinges, latches, guide rollers and gate catchers are sold separately; check the hardware list for your gate and confirm fit on the 4×4 in. profile with our team before drilling.
Material & finish
4×4 in. x 8ft. HD Square Post (.125 Thk) – Black is made from aluminum 6063-t6, finished with AAMA 2604 Super-Durable Powder Coating in black.
6063-T6 is an architectural aluminum alloy made for extruded profiles. It gives clean, consistent shapes and takes a powder coating evenly, which is why it is widely used for fences, gates and other exterior building products.
AAMA 2604 is the American Architectural Manufacturers Association specification for high-performance organic coatings, powder coatings included, on aluminum extrusions. It sets test requirements for outdoor color and gloss retention, chalking and corrosion resistance.
