Bring modern sophistication and lasting performance to any outdoor space with the Manhattan Corten Steel Tapered Rectangular Planter. Part of the Planters Unlimited Corten Collection, this planter pairs clean, contemporary lines with the exceptional durability of weathering steel. Each piece arrives with a rustic, pre-patinated finish, created through our factory patina process and protected with an external sealer for added longevity.
Corten steel is prized for its evolving character and strength. This iron-based alloy reacts naturally to moisture and the elements, developing a rich, earthy patina that forms a protective surface layer. The patina helps guard against deeper corrosion while delivering the warm, organic finish designers love.
To provide this signature look right away, Planters Unlimited accelerates the weathering process by applying a patina finish in-house and sealing the exterior to help minimize continued patina development and reduce potential runoff.
Every Manhattan planter is made to order for a precise fit in commercial or residential designs. Choose from sizes ranging from 30" to 120" in length and 18" to 48" in height. Need a custom size? Contact us for a quote online or call (888) 320-0626.

Specs & guidance: detailed information available in our Metal Guide Specifications
Note: Use care when placing Corten planters on sensitive surfaces, as rust transfer or staining may occur.
Corten steel planters offer a unique balance of architectural style, rugged durability, and natural beauty. As they weather, they become even more visually striking—without compromising structural integrity. The Manhattan Tapered Rectangular Planter is an ideal solution for hospitality spaces, streetscapes, commercial campuses, rooftop gardens, and high-end residential landscapes.
