Our Brampton corner modular planter is made from structural 2 mm Corten steel as standard, with the choice of having it weathered, with its distinct and beautiful orange patina, or un-weathered. The thickness of the Corten steel is more than enough to create durable structures that will stand the test of time and bespoke thicknesses can be ordered on request. Designed to connect easily to our straight modular planter sections, they allow you to create your own custom raised beds, complete with the unique protective properties and patina of beautiful Corten steel.
