Corten Steel Planter Boxes
Create strong, architectural garden features with Metwall’s modular Corten Steel Planter Boxes. Made from 1.6mm REDCOR® weathering steel, these Australian-made planter boxes combine clean lines, lasting strength and the distinctive rusted finish of Corten steel.
Each planter box features 50mm folded top and bottom edges for additional rigidity and a substantial, premium appearance. The panels are laser cut, precision folded and supplied with pre-drilled holes, making assembly straightforward.
Your planter box will initially arrive with a natural grey steel appearance. Once exposed to outdoor conditions, the REDCOR® steel will gradually develop its protective rust-coloured patina. The colour and texture will continue to evolve over the first few months, creating the warm, weathered finish for which Corten steel is known.
