5.5″ Aluminum Slat

It is a wide twin-cavity 6063-T6 aluminum extrusion with a nominal 5.500″ face and 0.803″ depth. It is designed as horizontal or vertical infill for compatible Alumission fences, gates, screens, wall toppers, railing applications, and custom panels.

Yes. The 5.5″ profile can be repeated throughout an entire panel. Use no gap for maximum visual coverage or introduce a consistent gap to create a more open architectural appearance.

Yes. A no-gap layout can be used when maximum privacy is the design goal. Plan the complete panel carefully and allow for the actual system, installation method, tolerances, movement, and local requirements.

Common design choices include no gap, 1/4″, and 1/2″, but the spacing can be customized. Smaller gaps reduce sightlines and increase privacy; larger gaps increase openness, visibility, light, and airflow.

Yes, when the application allows it. Larger custom gaps create a more open, see-through screen. Verify local opening limits, safety rules, climbability requirements, and the intended use before fabrication.

Yes. The 5.5″ profile can be combined with Alumission 2.5″ and 1″ aluminum slats to create mixed-width patterns, accent bands, repeating rhythms, and custom privacy designs.

Mixing profile widths gives you more control over proportion and visual rhythm. The 5.5″ slat provides broad coverage, the 2.5″ slat introduces a medium-width break, and the 1″ slat works well as a narrow accent.

Yes. Horizontal installation is a popular choice for modern aluminum fences and gates because it emphasizes long, clean architectural lines.

Yes. The same profile can be used vertically when the posts, frame, fastening method, and overall panel design are planned for vertical infill.

The profile is designed to work with Alumission post systems. The exact post configuration depends on whether the post is an end, line, corner, gate, wall-topper, or other application.

Yes. It can be used as infill in properly designed pedestrian gates, driveway gates, sliding gates, and other compatible Alumission gate frames.

Yes. The wide face and adjustable spacing make it well suited for privacy screens, equipment screens, wall toppers, and other architectural infill applications.

Yes. The displayed variation price is for one 5.5″ slat in the selected length and finish unless the product page specifically states otherwise.

No. Posts, frames, covers, caps, screws, brackets, spacers, and other installation components are sold separately unless specifically listed as included.

The nominal cross-section is 5.500″ wide × 0.803″ deep with a 0.053″ nominal wall thickness. Normal extrusion tolerances apply.

The profile is made from 6063-T6 aluminum, an alloy commonly used for architectural extrusions because it combines good form, finish quality, corrosion resistance, and practical strength.

It is a hollow twin-cavity extrusion. The two internal cavities help the wide profile maintain its shape while keeping it lighter than a solid aluminum bar.

No. Aluminum does not rust like ordinary steel. The powder-coated finish also adds an exterior protective and decorative layer for low-maintenance use.

No routine painting or staining is required. Clean the powder-coated surface with mild soap and water and avoid abrasive pads or harsh chemicals.

Yes. It can be field-cut with suitable aluminum-cutting equipment and a fine-tooth blade. Measure carefully, support the extrusion, and deburr cut edges before assembly.

Yes. Aluminum is a noncombustible material. The fire performance of a complete installed assembly can also depend on surrounding materials and project conditions.

Select from the current online length options shown on this product page. 10′ profiles are available by phone order only; they cannot be purchased online and shipping charges may apply.

Choose from the finishes currently displayed in the color selector above. Availability can vary by length and inventory, so the selector is the best source for the purchasable combinations.

Yes. Alumission aluminum profiles are made in the USA.

Yes. The modular Alumission system is designed to make many projects approachable with common measuring, cutting, drilling, and assembly tools. The exact tools and installation method depend on the project configuration.

Determine the finished panel dimension in the direction the slats will stack, subtract any required frame allowances, then divide the usable dimension by the 5.5″ slat face plus your selected gap. Mixed-width patterns should be laid out as a complete repeating sequence before ordering.

Yes. Gap size directly affects slat quantity, privacy, appearance, and total panel layout. Decide on the orientation and spacing first, then calculate the number of profiles needed for each opening.

Yes. For a custom pattern using 1″, 2.5″, and 5.5″ profiles, plan the opening dimensions, orientation, desired privacy, and repeating sequence before ordering. Contact Alumission if you want help confirming a material list.
