Guide
Aluminium has become the material of choice for architectural planters — and for good reason. It's light enough for rooftops, tough enough for the Australian climate, and finished to any colour you like. Here's why we recommend it for most residential, commercial and landscape projects.
Aluminium combines strength, light weight and corrosion resistance in a way few materials can. For planters — which live outdoors, hold wet soil and often sit on structures with weight limits — that mix is hard to beat. It's why architects and landscape designers specify it for everything from balcony troughs to large commercial installations.
Aluminium is roughly a third the weight of steel. On rooftops, balconies and podiums where structural load is limited, that difference is decisive: you get a large, substantial-looking planter without the weight penalty. It also makes delivery, handling and installation safer and faster.

Aluminium naturally resists corrosion and won't rust like mild steel. Paired with a quality powdercoat, it stands up to full sun, coastal salt air and constant moisture from soil and irrigation — holding its finish and structure for years.
Aluminium takes powdercoat beautifully, so you can match a planter to a facade, a brand palette or a planting scheme in virtually any colour or sheen — including textured and matte architectural finishes. Finishes can be matched consistently across an entire project.
No rust, no rot, no sealing. A powdercoated aluminium planter generally needs nothing more than an occasional wipe-down to keep looking its best — a real advantage for commercial sites and busy households alike.
Aluminium is one of the most recyclable materials available and can be reprocessed indefinitely without losing quality. A long service life plus full recyclability makes it a responsible choice for projects with sustainability targets.
For some looks a weathered Corten-steel aesthetic is the brief — we can advise where that suits and where powdercoated aluminium is the better long-term call.
