Why Choose Weathering Steel Planter Boxes?
1. Effortless Installation
Pre-drilled components align easily and secure using supplied fasteners. Large installations that traditionally required on-site fabrication can now be completed in hours instead of days.
2. No Ongoing Maintenance
Redcor® weathering steel develops a protective rusted patina that seals the surface. Even if scratched, the protective layer reforms naturally — no painting required.
3. Built for Australian Conditions
Manufactured from premium Australian BlueScope® steel, these planters are engineered for structural durability in extreme weather environments.
4. Self-Supporting Structure
Planters are typically supplied without bases to allow for free drainage. Optional custom bases and adjustable feet are available for rooftop and paved installations.
Available Sizes
500mm High Modular Box Planters
Available in square and rectangular formats ranging from 400mm x 400mm up to 2000mm x 400mm.
700mm High Modular Box Planters
Available in the same footprint sizes for deeper planting capacity and stronger visual impact.
With nine standard size options in each height, plus extender panels and corner modules, the system offers unmatched flexibility across residential and commercial landscaping projects.
