A 24 ft Alu 40 slat in black powder coat: long stock for sliding gates, wide openings, wall toppers and pergola infill, or for cutting several custom pieces from one length.
A 24 ft black aluminum slat for long spans and custom cuts
This 24 ft black aluminum slat is the long-stock version of the Alu 40 profile. It suits projects where standard 8 ft pieces would mean extra joins, such as wide sliding gates and long wall toppers, and it gives fabricators and installers raw length to cut several custom pieces from a single slat.

Where long stock helps
- Sliding gates: a single length can cross a wide gate frame with no visible break.
- Wall toppers: fewer joins along a long masonry wall keep the line clean.
- Pergola infill: cut to the exact bay width of a patio structure.
- Custom fences: cut to odd section widths to reduce offcut waste.
- Fabrication: keep stock on hand for several small jobs and cut as needed.
Pair the slats with a frame from our aluminum gates range, or see the pergola category for patio structures.
Planning and handling
A 24 ft piece needs space to unload, store flat and cut. Plan cut lists before ordering so each length yields usable pieces, and support the slat along its length while cutting to protect the powder-coated finish. Delivery or pickup of long lengths depends on your location, so confirm with our team.


Getting more from each length
One 24 ft slat equals three 8 ft pieces, but it gives you more options: you can cut two 10 ft pieces for a wide gate and keep the rest for a short return, or split it into pieces that match an odd bay width exactly. Planning cuts across all your slats before ordering usually reduces offcuts and the number of lengths you need. Keep the black finish consistent with posts, caps and frames so cut pieces blend into the rest of the project.
This slat belongs to the Gen 2.0 by-the-piece series. For standard 8 ft sections, the 8 ft black Alu 40 slat is easier to handle; if you are matching an existing fence, tell us which system it uses.
Material & finish
What it is made of
ALU 40 Slat 24 ft. – 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.
