CORTEN AND STEEL PLANTER BOXES IN MELBOURNE
Westberg Sheetmetal fabricates custom steel and Corten planter boxes for commercial and residential projects in Melbourne. We build to any dimension and specification — Corten weathering steel or powder-coated mild steel in any RAL colour — and deliver across Victoria.
MILD STEEL OR CORTEN — WHAT'S THE DIFFERENCE?
MILD STEEL — ANY COLOUR
Mild steel planters are fabricated and powder coated in your chosen RAL colour. The powder coat provides a durable, weather-resistant finish. Commonly specified for commercial projects where colour matching to a brand palette or architectural scheme is required. Colour is consistent and long-lasting.
Best for: Commercial projects · Brand colour matching · Contemporary residential · Indoor use
CORTEN — THE LIVING FINISH
Corten (weathering steel) develops a stable rust-coloured patina when exposed to the elements. No coating is required — the patina is the finish, and it becomes more characterful over time. Increasingly specified by architects for outdoor landscaping, feature walls, and residential gardens. Once the patina forms, the steel does not continue to corrode.
Best for: Outdoor residential · Architectural landscaping · Feature gardens · Natural material aging
Corten requires an initial weathering period outdoors. We can discuss sealing options if required.

What is Corten steel and why is it used for planters?
Corten (also known as weathering steel) develops a stable rust-coloured patina when exposed to weather. This patina acts as a protective layer — the steel does not continue to corrode once the patina has formed. It's widely used for architectural planters, garden features, and landscape projects where a natural, characterful finish is desired.
