Custom aluminium retaining walls

Can aluminium be used for retaining walls?

Yes — aluminium is used for raised garden beds, planter walls and low landscape and retaining walls, offering a lightweight, rust-proof, modern alternative to timber sleepers, concrete and steel. The retained height and loads are engineered to suit, and for significant structural earth retention the design is engineered accordingly. POBOX makes custom aluminium retaining and planter walls to measure.

Aluminium vs steel, timber and concrete retaining walls?

Aluminium is lighter than steel and concrete, won't rust like steel or rot like timber, needs little maintenance and comes in any powder-coat colour — ideal for raised beds, planter walls and low landscape retaining. Concrete and heavy steel suit large structural retention. POBOX selects the material to suit the height and site.

Do aluminium retaining walls rust?

No — aluminium doesn't rust, and a powder-coat adds a durable, UV-stable finish, so aluminium retaining and raised-bed walls suit coastal, wet and planted settings where steel would corrode and timber would rot. POBOX finishes with coastal-grade options for exposed sites.

How high can an aluminium retaining wall or raised bed be?

Height is engineered to the retained load, the material gauge, internal framing and fixing — low landscape walls and raised beds are common, and taller walls are engineered to suit or paired with a structural system. POBOX engineers each wall for its height and situation.

Are aluminium raised garden beds any good?

Yes — aluminium raised garden beds are lightweight, rust-proof, long-lived and finishable in any colour, and can be made to any size and shape with drainage and liners. They are a clean, modern alternative to timber sleeper beds. POBOX makes raised beds to measure.

Can aluminium retaining walls be custom made to any size and colour?

Yes — sheet is laser-cut, folded and welded, so walls can be made to any length, height and profile — straight, stepped or curved — then powder-coated in any colour. POBOX makes every wall to measure.

Do aluminium retaining walls need drainage?

Yes — like any retaining or raised planting, drainage behind the wall and liners are detailed to move water away and protect the wall and any structure behind it. POBOX details drainage and liners as part of the design.

Are aluminium retaining walls suitable for coastal or sloping sites?

Yes — powder-coated aluminium suits coastal and exposed sites because it is rust-proof and available in coastal-grade finishes, and walls are engineered and stepped to suit slopes and level changes. POBOX designs to the site.

How much do custom aluminium retaining walls cost?

Cost depends on length, height, gauge, finish and engineering; custom walls are priced per project. Send your dimensions and site detail to POBOX for a quote.
