What “LD .080” actually means

Outside size creates presence. Wall thickness defines the structural class.

A 3.15-inch square post looks substantial, but Aluglobus intentionally identifies this version as Light Duty because the aluminum wall is .080 inch. The custom-color SKU also identifies 6063-T6 aluminum. Separate 3-inch .125-wall HD posts remain available when the project requires a heavier structural class.

3.15″ × 3.15″ footprintBroader than the compact 2×2 family, giving larger fence panels and gate openings a more substantial visual support.

.080″ wallThe published wall thickness makes the post class transparent and easier to compare against heavier options.

LD versus HDUse Light Duty where .080 is appropriate. Move to the separate .125-wall HD family when engineering, wind area or hinge loads require more wall material.

Why choose the 8 ft version

Keep the larger 3.15″ architectural footprint without buying extra post length the project does not need.

Eight-foot stock is the more efficient choice when the approved finished height, mounting condition and grade can all be resolved within the available length. The post keeps the same .080 Light Duty wall class and 6063-T6 aluminum while reducing unnecessary cut-off material compared with the 11 ft version.

Less excess material

When 8 feet is enough, the project avoids paying for and cutting away extra long-stock material.

Easier handling

Eight-foot extrusions are simpler to transport, stage and maneuver on many residential and light-commercial jobsites.

Standard-height efficiency

Use this length when the approved above-grade height and structural mounting fit comfortably within the available stock.

Clear upgrade path

Move to the 11 ft LD version when more length is required, or to the .125-wall HD family when the structural class itself must increase.

Important: 8 ft is supplied stock length, not a universal finished fence height or footing depth. Confirm the approved mounting and embedment before ordering or cutting.

Custom finish planning

Use the larger post as part of the property palette, not as an isolated color decision.

Aluglobus offers custom powder coating in any RAL color across its aluminum fence program, with matte, satin, textured and gloss options. The 3.15-inch post can therefore coordinate with fence panels, gates, wall cladding, window frames, exterior trim and other metalwork instead of being limited to a stock finish.

White & light neutralsReduce the visual weight of a larger 3.15-inch post and coordinate naturally with bright stucco, coastal architecture and minimalist façades.

Grey & anthraciteCreate a contemporary support line that pairs with modern windows, garage doors, roofing and darker exterior details.

Bronze & earth tonesWork well beside stone, brick, wood-look aluminum and warm architectural materials.

Texture & glossMatte, satin, textured and gloss choices can change how a large post reads in sunlight even when the base color is similar.

Screen colors are design references only. Confirm the final powder code, gloss, texture and required coating specification before production because displays cannot reproduce a physical finish exactly.

Post + cap

Technical specifications

The product publishes size, length and wall class. Project loads still need project answers.

The live product page identifies the post as 3.15×3.15 inches, 8 ft long, Light Duty, .080 thickness and 6063-T6 aluminum, with a custom-color post and matching custom-color flat press cap in the grouped selector.

Specification boundary: the public selector does not publish the alloy, allowable load, universal wind rating, fixed post spacing or one footing size for this exact individual post.

LD versus HD

The meaningful comparison is .080 wall versus .125 wall, not 3.15 inches versus 3 inches.

Aluglobus puts these post classes side by side in its gate selector. Similar outside dimensions can serve very different structural roles.

Decision	3.15″ × 3.15″ LD	3″ × 3″ HD family	What to verify
Wall	.080″ published	.125″ published on HD family	Which wall class does the design require?
Outside footprint	3.15″ square	3″ square	Is the choice visual, structural, or both?
Long stock	11 ft black option	8 ft and 12 ft HD options appear in Aluglobus selector	How much length remains after mounting?
Gate support	Optional gate context, Light Duty class	Stronger direction for higher hinge loads	Leaf width, weight, wind area, automation and foundation
Best fit	Large-profile support where .080 is sufficient	Higher-demand fence and gate conditions	Use actual loads, not appearance alone

Applications

A bigger post can improve proportion without automatically becoming a heavy-duty post.

The 3.15-inch footprint works well where compact 2-inch posts would look undersized beside larger panels, taller fencing or wider architectural bays.

Residential

Larger fence panels

A broader black support can look more proportional beside substantial aluminum fence sections.

Privacy

Architectural screening

The larger footprint suits privacy designs visually, but full-privacy wind area must still be checked against the .080 LD class.

Grade

Stepped & sloped runs

Eleven feet provides more final-cut flexibility where finished elevations change along the fence.

Gate system

Compatible lighter gate use

The post is offered in Aluglobus gate options, but hinge loads must be checked before using the LD profile as a gate support.

Commercial

Light-duty perimeter support

Useful where the larger visible profile is desired and the project does not require the separate .125 HD class.

Design-led

Custom-color verticals

The 3.15-inch square footprint creates a strong architectural rhythm while the selected finish controls how dominant or subtle the post feels.

Market perspective

Around the 3-inch size, heavier commercial and industrial aluminum posts commonly move to .125 walls.

Ultra Aluminum lists 3″ × 3″ commercial and industrial posts at .125 wall. That reinforces why this Aluglobus 3.15″ × 3.15″ .080 profile is appropriately identified as Light Duty instead of being marketed as HD based on outside size alone.

Market signal	Aluglobus 3.15″ LD	Heavier commercial direction
Outside size	3.15″ square	About 3″ square
Wall	.080″	.125″ commonly appears in heavier 3″ commercial / industrial offerings
Intent	Large footprint, lighter wall class	Higher structural class
Buying rule	Use where .080 meets the actual requirement	Upgrade where wind, privacy area or gate leverage requires more wall

System context

The 3.15″ custom-color post should be planned with panel proportion, alignment and finish continuity.

These Aluglobus system images show how posts, panels and gates work as one visual system. The images illustrate design context and finish coordination rather than claiming every pictured project uses this exact 8 ft post SKU.

Factory finish program

Custom color should be specified with the coating process, not after the structural post is chosen.

Aluglobus describes its aluminum fence program as custom powder coat in any RAL color with matte, satin, textured and gloss options, supported by 7-stage preparation and an AAMA-grade UV-resistant architectural finish.

Installation planning

Eleven feet gives flexibility, but it also magnifies layout mistakes.

Before concrete or structural fasteners are finalized, establish the post class, complete layout, finished elevations, approved mounting design and the final powder-coat specification.

Before installation: verify that .080 LD is suitable for the panel area or gate loads, then confirm spacing, grade, footing or base design and local requirements.

Confirm LD is the correct class

Review fence height, privacy area, wind exposure and gate loads before selecting .080 over the .125 HD family.

Approve the color and post class

Confirm the .080 LD support role together with the powder code, gloss and texture before material goes into production.

Map every support condition

Separate line, end, corner and gate positions so one post is not automatically used everywhere.

Establish finished elevations

Use a laser, level or string line to determine the final top line and cut length.

Determine the structural mounting

Size footings or bases from actual soil, wind, fence height and load conditions.

Set plumb in both directions

Tall posts make small base errors more obvious, so verify vertical alignment carefully.

Sight the full run

Check the entire line before finalizing concrete or structural fasteners.

Install compatible panels or gate hardware

Use the connection details specified for the selected Aluglobus system and verified post role.

Install the flat press cap

After final cuts and alignment, clean the post top and finish it with the matching 3.15-inch cap.

Frequently asked questions

Know exactly what the 3.15″ × 3.15″ × 8 ft LD custom-color post is before ordering it.

The core distinction is simple: larger footprint, efficient 8 ft stock, .080 Light Duty wall and a coordinated custom finish.

What are the exact dimensions?

The live product page lists the post as 3.15 inches by 3.15 inches square and 8 feet long.

What is the wall thickness?

The published wall thickness is .080 inch, and Aluglobus labels the profile Light Duty.

What aluminum alloy is used?

The live product page identifies 6063-T6 aluminum for this exact custom-color SKU.

What cap is grouped with the post?

The grouped selector includes a 3.15-inch Flat Press Cap in Custom Color as a separate selectable quantity.

Can I order the post in a custom RAL color?

Aluglobus advertises custom powder coating in any RAL color across its aluminum fence program, with matte, satin, textured and gloss options. Confirm the exact powder code and availability before production.

Why is this post called Light Duty if it is over 3 inches square?

This 3.15-inch post uses a .080 wall, while Aluglobus separately offers .125-wall HD post families for heavier structural conditions.

Is the finished fence automatically 8 feet high?

No. Eight feet is supplied extrusion length. Final above-grade height depends on mounting, embedment, grade and any field cut.

When should I choose the 11 ft LD version instead?

Choose the 11 ft Light Duty version when the approved installation needs more stock for deeper embedment, taller finished height, larger grade changes or additional field-cut flexibility while remaining in the .080 LD class.

When should I move to the .125-wall HD family?

Move to the HD family when fence height, privacy area, wind exposure, spacing, hinge loads or engineering requirements exceed the .080 Light Duty class.

How should the custom finish be planned?

Approve one powder code, gloss and texture direction for the post, flat press cap and matching aluminum components before production. Screen colors should not be treated as the final physical color standard.

Factory-direct custom aluminum post profiles

Choose the structural class and finish before the 11 ft post goes into production.

Select the 3.15″ × 3.15″ × 8 ft .080 LD custom-color post and matching flat press cap from the product options, or send Aluglobus the project layout when you need help deciding between 8 ft versus 11 ft stock, LD versus HD support, or the finish package.
