3x3 in. x 12 ft. HD Square Post (.090 Thk) - Custom Color

A 12 ft heavy-duty square post with the finish freedom to match the project.

The 3×3 in. x 12 ft. HD Square Post (.090 Thk) – Custom Color is specified as a 3-inch square aluminum support profile with a .090-inch heavy-duty wall and 12-foot supplied length. It is designed for projects where the lighter .080 LD post class is not the right structural direction, while still remaining distinct from Aluglobus’ heavier .120/.125-wall 3-inch HD post options.

The .090 HD identity matters just as much as the 3-inch outside size.

Aluminum posts should be compared by outside size, wall class, length and application. This product is identified as the 3″ × 3″ × 12 ft .090 HD custom-color post. The current custom-color catalog copy describes Heavy Duty reinforced architectural aluminum but does not independently publish a wall value in its technical table, so engineered submittals should confirm the production-order wall thickness.

A 12 ft structural post should match the architecture, not be forced into an unrelated stock color.

Aluglobus’ aluminum fence program offers custom powder coating in any RAL color, with matte, satin, textured and gloss options. That lets the 3-inch HD post coordinate with fence panels, gates, exterior trim, cladding, windows and other metalwork across the property.

Screen swatches are design references only. Confirm the physical powder code, gloss, texture and required architectural coating specification before production.

Long stock gives more flexibility for tall fences, deeper approved support and changing grade.

A 12-foot extrusion is useful when standard 8-foot posts do not provide enough total length for the approved finished height and structural mounting. The extra stock can also simplify field cutting across projects with changing elevations.

Taller approved layouts

More stock length gives designers and installers room for taller fence conditions when the .090 HD class is appropriate.

More embedment flexibility

Longer material leaves more post available below grade when the project-specific footing design requires it.

Grade changes

Sloped and stepped properties often require different final cut lengths along one fence run.

Field-cut versatility

Starting with 12 ft allows the installer to cut down after finished elevations are confirmed instead of starting short.

The custom-color post is sold on its own. Add a matching 3-inch cap only when the project needs one.

The live custom-color product is a standalone post listing. Aluglobus separately lists a 3″ Aluminum Cap – Custom Color in its gate-parts selector, so the cap should be treated as an optional accessory rather than part of this post SKU.

Use the exact SKU values, then keep engineering values project-specific.

The live custom-color product confirms a 3″ × 3″ profile, 12 ft supplied length, Heavy Duty reinforced architectural aluminum construction and a custom powder-coated finish. The .090 wall designation is retained as the current product identity, while engineered submittals should confirm the wall and alloy on the production order.

Engineering

Confirm wind, load, spacing and footing requirements for the specific project

Twelve feet solves a stock-length problem. HD wall class solves a load problem.

A longer extrusion can provide more embedment or finished-height flexibility, but it does not automatically make the post suitable for every tall fence or gate. The correct support still depends on wall thickness, panel area, wind exposure, spacing and gate leverage.

Where a 12 ft .090 HD post can make sense.

Use the HD post where the project benefits from additional wall thickness and long stock, but still verify the actual loads before assuming .090 is enough for every heavy condition.

A 12 ft custom-color HD post should be specified as part of the complete fence or gate system.

These Aluglobus system images illustrate how posts, panels, gates and finishes work together. They provide design context rather than claiming every pictured project uses this exact custom-color SKU.

Specify the color and coating performance together.

The live product confirms a custom powder-coated finish. Aluglobus’ broader aluminum fence program offers any RAL color, matte, satin, textured and gloss options, supported by 7-stage preparation and AAMA-grade UV-resistant architectural finish positioning.

Twelve-foot posts need the footing, alignment and final elevation solved before installation.

The live product supports concrete footings, deep-set structural use, gate hinge support, trimming with proper metal-cutting tools and integration into modern fence systems. Treat those as installation options, then size depth and anchoring from the real project rather than a generic rule.

Confirm the HD post specification

Verify the .090 wall and alloy on the production order when engineering or permitting depends on those values.

Map every support role

Separate line posts, corners, ends and hinge posts because one wall class may not be correct everywhere.

Establish finished elevations

Use a laser, level or string line to determine how much of the 12-foot extrusion is actually needed at each location.

Design the structural mounting

Size concrete footings, bases or other supports from the real loads, soil and site conditions.

Set posts plumb in both directions

Long posts amplify small base errors, so verify vertical alignment before concrete or structural fasteners are finalized.

Sight the full run

Check the complete post line before installing fence panels or gate hardware.

Cut only after elevations are confirmed

Use suitable non-ferrous cutting equipment, protect the finish and deburr the final cut.

Install the 3-inch cap

Clean the finished post top and install the matching black aluminum cap after final cuts and alignment are complete.

The live product includes gate support, but hinge loads still need to be checked.

Aluglobus specifically lists gate hinge support and continuous gate-system use among the applications for this custom-color post. That establishes a real gate-use context without making one 3-inch post universally correct for every driveway or pedestrian gate.

Custom powder-coated aluminum keeps routine care simple.

The live product page positions this post as a low-maintenance exterior support. Routine care is mainly about keeping the powder-coated surface clean and inspecting the complete fence or gate system rather than repainting, oiling or staining the post.

Mild cleaning

Use water and a mild cleaner when dirt, salt or environmental residue builds up on the powder-coated surface.

No staining cycle

Unlike wood support posts, the aluminum profile requires no oil, sealing or staining as part of routine maintenance.

Protect the coating

Avoid unnecessary abrasion during installation and address chips or field damage according to the approved finish-repair method.

Inspect the system

For gates and taller fences, periodically inspect fasteners, hinges, alignment and foundations because structural performance depends on the complete installation.

Know what the 3″ × 3″ × 12 ft .090 HD custom-color post is before ordering it.

The important decisions are the 12 ft stock length, verified HD role, custom finish, gate or fence loads and the values that need confirmation for engineering.

Confirm the post specification and custom finish before the 12 ft extrusion goes into production.

Select the 3″ × 3″ × 12 ft .090 HD custom-color post from the product options, or send Aluglobus the fence or gate layout when you need help confirming the support specification, finish package or compatible 3-inch cap.
