3mm Corten Steel Planters

Turn heads in your garden or terrace with a rustic steel planter that ages beautifully and lasts for decades.

The 3mm Corten Steel Planters are built for durability and visual impact in modern landscapes. Made from thick, pre-weathered Corten steel, these planters develop a protective rust-like patina over time, creating a warm, industrial finish that blends beautifully with natural surroundings. 

Each planter is fully welded with smooth edges and crafted in-house by the Online Metal Store team. Choose between a fully assembled version or a flat-pack component kit for easier handling and installation. Designed for architects, designers, and homeowners who want strength, elegance, and zero maintenance.
