2.5″ Aluminum Slat

0 (0) Reviews

A powder-coated 6063-T6 aluminum slat for horizontal or vertical fence and gate designs. Use it alone or combine it with 1″ and 5.5″ slats to create custom privacy, semi-private, and open patterns. Available online in 6′ and 8′ lengths.

Price range: $44.04 through $69.59

The 2.5″ Aluminum Slat is the versatile middle-width profile in the Alumission slat family—wide enough to create strong visual coverage, yet narrow enough to support detailed patterns and precise spacing. Its clean rectangular face works in modern aluminum fences, gates, privacy screens, wall toppers, and custom architectural panels without making the finished design feel too heavy.

Use the 2.5″ slat by itself for a consistent, balanced layout. Tight gaps create a more private appearance, while larger spaces introduce light, air, and visibility. A layout with gaps approaching 4″ produces a noticeably more open, see-through design; smaller spacing reduces sightlines and gives the panel a more continuous look. The gap is a design choice and should always be checked against the project’s safety and local-code requirements.

For a more custom pattern, combine the 2.5″ profile with Alumission’s 1″ Aluminum Slat or 5.5″ Aluminum Slat. Alternate widths, repeat a rhythm, create narrow accent bands, or use a wider 5.5″ slat as the dominant element with 2.5″ and 1″ profiles as visual breaks. Varying both slat width and gap size gives designers and homeowners far more control than a single-profile fence.

The profile can be installed horizontally or vertically with Alumission post systems. Horizontal layouts can make a property line look wider and emphasize long architectural lines. Vertical layouts create height, rhythm, and a more traditional picket direction with a clean contemporary finish. The surrounding posts, frame members, fastening method, and spacing plan must support the chosen orientation.

Extruded from lightweight 6063-T6 aluminum, the hollow 2.500″ × 0.803″ profile is easy to handle, measure, cut, and assemble. Its powder-coated exterior is designed for low-maintenance outdoor use, while aluminum’s natural corrosion resistance means it will not rust like steel.

Control Privacy and Visibility

Choose the Gap That Creates the Right Look

The same 2.5″ slat can produce very different results depending on its orientation and the open space between profiles.

Tight-Gap Privacy

Place 2.5″ slats with small, consistent gaps to reduce sightlines and create a more private, visually continuous panel while retaining a crisp horizontal or vertical reveal.

Balanced Semi-Privacy

Use moderate spacing to soften the solid-wall effect. This approach introduces controlled light and airflow while keeping the 2.5″ profile visually dominant.

Open 4″ Spacing

A gap near 4″ creates a lighter, more see-through fence or screen. Verify opening limits, climbability rules, and safety requirements for the exact application before fabrication.

Horizontal or Vertical

Run the slats horizontally to emphasize width and long modern lines, or vertically to emphasize height and repetition. Alumission posts can support either design when the complete frame is planned correctly.

Build a Custom Slat Pattern

Mix 1″, 2.5″, and 5.5″ Profiles

Use the 2.5″ profile as the bridge between narrow accent slats and wider privacy slats to create a pattern unique to the project.

2.5″ Slats Only

Repeat one profile width for a calm, uniform design. Change only the gap to move from greater privacy to a more open architectural screen.

Add 1″ Accents

Combine with the 1″ Aluminum Slat to introduce finer lines, smaller visual breaks, or repeating narrow accent bands.

Pair With 5.5″ Slats

Use the 5.5″ Aluminum Slat for broader coverage, then place 2.5″ slats between wider sections to add proportion and rhythm.

Combine All Three Widths

Create a deliberate sequence using 1″, 2.5″, and 5.5″ profiles. Plan the full panel on paper first so the pattern, end spacing, cut lengths, and quantity remain consistent.

Included: One 2.5″ Aluminum Slat in the selected length and powder-coated finish.

Questions & Answers

2.5″ Aluminum Slat Questions & Answers

Detailed answers about privacy, gap planning, mixed-width designs, horizontal and vertical layouts, dimensions, installation, finishes, ordering, and care.

Product & Design

What is the 2.5″ Aluminum Slat?

It is a hollow 6063-T6 aluminum extrusion with a nominal 2.500″ face and 0.803″ depth. It is used as horizontal or vertical infill in compatible Alumission fence, gate, screen, wall-topper, and custom panel systems.

Why choose the 2.5″ slat instead of a narrower or wider slat?

The 2.5″ face offers a useful balance between coverage and pattern flexibility. It creates more visual presence than a 1″ accent slat but allows more detailed spacing and repetition than a wider 5.5″ privacy slat.

Can I build a complete panel using only 2.5″ slats?

Yes. Repeating only the 2.5″ profile creates a uniform design. Use smaller gaps for greater privacy or larger gaps for a lighter, more open appearance.

Can it be used for both fences and gates?

Yes. It can be used as infill in properly designed fence panels, pedestrian gates, driveway gates, sliding gates, privacy screens, and wall toppers.

Is this a solid or hollow aluminum profile?

It is a hollow rectangular extrusion. The hollow construction provides clean architectural lines with less weight than a solid bar.

Is each profile sold individually?

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

Privacy, Gaps & Layout

How does the gap between slats affect privacy?

Smaller gaps reduce sightlines and create a more private appearance. Larger gaps allow more light, airflow, and visibility through the panel.

Can I use very small gaps between 2.5″ slats?

Yes, when the complete assembly and fastening method allow it. Plan a consistent reveal and leave any clearance required for fabrication, drainage, expansion, and installation.

Can I use a 4″ gap between slats?

Yes, a gap near 4″ can create an open, see-through architectural design. Confirm that the opening complies with local rules for the specific fence, gate, pool barrier, guard, or property application.

What gap gives full privacy?

A true full-privacy result generally requires an overlap, interlocking system, or a layout that eliminates direct sightlines. Small open gaps improve privacy but can still allow angled visibility.

Will a horizontal layout look different from a vertical layout?

Yes. Horizontal slats emphasize width and long modern lines, while vertical slats emphasize height and repetition. The same gap can feel different depending on orientation and viewing angle.

How do I keep every gap consistent?

Use accurately sized temporary spacers or a repeatable layout jig, verify the first several slats with a tape measure, and recheck the total pattern before fastening the complete panel.

Should the end gaps match the gaps between slats?

Usually a centered, balanced layout looks best, but the end condition depends on the post channel, frame, cover, and fastening method. Plan the complete opening before cutting or installing profiles.

Combining Different Slat Sizes

Can the 2.5″ slat be combined with 1″ slats?

Yes. Use 1″ slats as narrow accents between 2.5″ profiles, create repeating bands, or alternate the widths to produce a more detailed custom pattern.

Can it be combined with 5.5″ slats?

Yes. A 5.5″ slat can provide broad coverage while 2.5″ profiles introduce smaller sections, breaks, and visual rhythm.

Can I combine 1″, 2.5″, and 5.5″ slats in one panel?

Yes. All three widths can be combined in a planned horizontal or vertical pattern. Draw the sequence first so the total width or height, gaps, quantities, and end spacing fit the finished opening.

Do mixed slat widths need the same gap?

No. Gaps may be uniform or intentionally varied, but a deliberate repeating rule usually produces the cleanest result. Verify that every opening remains suitable for the application.

How do I calculate a mixed-width pattern?

Add the face widths of every slat in one repeating sequence, add the planned gaps, and compare that total with the clear panel dimension. Repeat the module as needed, then divide any remaining space deliberately at the ends or within the pattern.

Orientation & Compatibility

Can the 2.5″ slat be installed horizontally?

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

Can it be installed vertically?

Yes. Vertical installation creates height and a contemporary picket-style rhythm. Use suitable top and bottom frame support and a fastening method designed for the complete panel.

Which Alumission posts can be used with this slat?

The 2.5″ slat is designed for use with Alumission post systems. Select the post style, channel arrangement, covers, and hardware that match the fence or gate layout.

Can I change from horizontal to vertical without changing the slat?

The slat profile can be used in either direction, but the surrounding frame, support, cut lengths, attachment points, and installation sequence must be planned for the selected orientation.

Can it be used with wood, masonry, or steel structures?

It may be incorporated into a properly designed custom assembly, but connections, isolation between dissimilar materials, moisture control, structural support, and local requirements must be reviewed for that project.

Dimensions & Installation

What is the exact profile size?

The nominal overall size is 2.500″ wide × 0.803″ deep.

What is the wall thickness?

The nominal wall thickness shown on the technical drawing is 0.053″. Normal extrusion tolerances apply.

What material is the profile made from?

It is extruded from 6063-T6 aluminum, an architectural alloy commonly selected for clean extrusion quality, corrosion resistance, finishing, and outdoor aluminum systems.

How much does the slat weigh?

The profile weighs approximately 0.408 lb per linear foot. Actual shipping weight can vary with length, finish, packaging, and normal manufacturing tolerances.

Can the slat be cut to a custom length?

Yes. Use suitable aluminum-cutting equipment with a fine-tooth blade, support the extrusion securely, wear appropriate protection, measure carefully, and deburr every cut edge.

How many 2.5″ slats do I need?

Quantity depends on the clear panel dimension and selected gap. For a single-width layout, estimate by dividing the clear stacking dimension plus one gap by 2.5″ plus one gap, then confirm the end spacing and actual installation details before ordering.

Are posts, screws, spacers, and covers included?

No. The selected product variation includes one 2.5″ slat. Posts, frames, screws, spacers, covers, caps, brackets, and installation accessories are sold separately.

Finish, Outdoor Use & Maintenance

What colors are available?

Available finishes are Black, Bronze, White, Dark Gray, and Light Gray.

Is the slat powder coated?

Yes. The exterior aluminum surface is powder coated for a durable, coordinated finish with compatible Alumission components.

Will every powder-coated part match?

Yes. Mass-production powder coating is very accurate. For the best visual result, compare all components together before final assembly.

Can the slat be used outdoors?

Yes. The 6063-T6 aluminum construction and powder-coated finish are suitable for outdoor use when the complete system is properly designed, drained, installed, and maintained.

Will a cut edge rust?

No. Aluminum does not rust like steel.

How should the finish be cleaned?

Wash with mild soap and clean water using a soft cloth or sponge. Rinse thoroughly and avoid abrasive pads, harsh solvents, and aggressive chemicals.

Ordering, Lengths & Shipping

What lengths can I buy online?

6′ and 8′ lengths are available for online purchase in the listed finishes, subject to current stock.

Can I order a 10′ slat?

Yes. The 10′ length is available by phone order with an Alumission representative. It cannot be purchased online, and shipping charges may apply.

Why is the 10′ option visible but not clickable?

It is displayed so customers know the longer length is available. Long-profile packaging and shipping must be reviewed by an Alumission representative before the order is placed.

How do I see the exact price?

Select an online length and color. The general price range will be replaced by the exact price for that specific variation.

Can long-profile shipping cost extra?

Yes. Carrier limits, oversize packaging, destination, and order quantity can affect shipping charges, especially for phone-order lengths.

Can a cut or modified slat be returned?

Cut, drilled, installed, damaged, or otherwise modified material may not be eligible for return. Review the current return policy and confirm quantities and measurements before fabrication.

Performance & Safety

Is the 2.5″ slat fireproof?

Yes. The aluminum profile is noncombustible. Fire performance of the complete fence or gate also depends on posts, coatings, fasteners, adjoining materials, and the installed assembly.

Is the slat structural by itself?

No. It is an infill profile, not a complete structural system by itself. Posts, frames, foundations, spans, connections, wind exposure, loads, and local requirements must be considered together.

Can I use a 4″ gap around a pool or elevated guard?

Do not assume a 4″ gap is automatically permitted. Pool barriers, guards, stairs, balconies, and other safety applications may have strict opening, climbability, height, and load rules. Confirm every applicable local requirement before construction.

Who should install the slats?

A qualified installer familiar with aluminum fence and gate systems is recommended for large panels, gates, elevated guards, pool barriers, or any code-regulated project.
