Custom Metal Planters — Corten, Steel & Aluminum

Corten steel planters are generally considered safe for ornamental plants. For edible plants, a food-safe liner is recommended to prevent direct contact between soil and the metal surface. Aluminum planters are a naturally inert option and are frequently chosen for herb gardens and vegetable planters where soil contact is a concern.

Corten steel planters are engineered for decades of outdoor use — the patina layer that forms acts as a self-protecting barrier against further corrosion. Powder-coated steel planters typically last 10–20 years depending on climate and coating quality. Aluminum planters are rust-proof by nature and can last indefinitely with minimal maintenance in most outdoor environments.

Yes. All planters from Custom Metal Home are made to order. You can specify exact dimensions — length, width, height, and wall thickness — as well as shape, including rectangular troughs, square boxes, L-shapes, and tapered forms. Custom drainage hole placement and mounting provisions can also be incorporated into the fabrication.

Yes, proper drainage is critical to prevent waterlogging and root rot. Custom Metal Home can fabricate drainage holes directly into the base of each planter. For installations on rooftops or elevated decks where drainage must be controlled, overflow ports or raised-feet designs can be incorporated to manage water flow without damaging surrounding surfaces.

Steel planters can be finished in a wide range of powder-coat colors, providing UV resistance, scratch resistance, and a polished aesthetic. Corten planters are typically left to weather naturally, though a pre-weathered finish is available for projects that require an immediate aged appearance without waiting for the natural patina development process to complete.

Pricing is based on material type, wall thickness, overall dimensions, quantity, and any special fabrication requirements such as custom cutouts, integrated trays, or specialty coatings. Because every planter is made to order, Custom Metal Home provides pricing on request. Contact the team with your project specifications to receive an accurate, detailed quote.
