Yes, corten steel planters are safe and excellent for plant growth. The iron in corten steel promotes chlorophyll development in plants, leading to healthy harvests. Additionally, corten steel planters are durable and low-maintenance, making them a practical choice for gardening. The protective rust layer that forms on corten steel does not release harmful chemicals into the soil and can actually benefit plant growth. While corten steel can absorb heat, this can be advantageous for plants, especially in cooler climates. As long as the interior of the planter is lined with a food-grade waterproofing coat, corten steel is suitable for growing edible plants like vegetables, fruits, and herbs.

For durable corten planter boxes, a minimum thickness of 1/8 inch (11 gauge) steel is recommended, ensuring both longevity and structural stability. Opting for thicker steel, such as 3/16 inch, enhances durability further, albeit at a higher cost. Thinner steel may risk denting and deflection once filled with soil and plants. Ultimately, choosing the right thickness is crucial for maximising the lifespan of corten steel planter boxes, with thicker options offering superior performance and longevity.

We often get asked about the difference between corten steel and weathering steel. The truth is, they’re the same thing: corten is simply the trademarked name for a specific type of weathering steel. Both materials develop a distinctive rust-like patina that provides enhanced corrosion resistance compared to regular carbon steel. This makes corten/weathering steel an ideal choice for outdoor furniture, structures, and architectural features that need to withstand the elements. As a leading fabricator of custom corten steel products, we can attest to the exceptional durability and visual appeal of this material. 

When it comes to corten steel planter boxes, the decision to paint them hinges on personal style and aesthetic preferences. While the natural rust patina of corten steel adds a unique, weathered charm appreciated by many, the painting offers customisation options to match your garden’s theme. However, it’s essential to weigh the advantages and disadvantages carefully. Painting provides added protection against corrosion and allows for colour coordination, but it also eliminates the distinctive corten appearance and may require periodic touch-ups. Consider testing a small area first to ensure the colour aligns with your vision, or embrace the raw beauty of unpainted corten steel for a timeless appeal.

To prevent staining from weathering steel garden edging:

  1. Allow the steel to fully weather (6 months) before installing.
  2. Offset edging from adjacent surfaces.
  3. Mist/wipe down steel during initial weathering.
  4. Consider pre-rusting/pre-weathering steel.
  5. Apply sealant after the desired patina to lock in the look.

By managing the weathering process carefully, corten steel can be a durable and low-maintenance option for garden edging.

Weathering steel garden edging is renowned for its exceptional durability and longevity. Under optimal conditions, such as low humidity, minimal soil salinity, and a neutral pH environment, this robust material can endure for up to a century—that’s right, 100 years! Even in less favourable circumstances, you can expect your weathering steel edging to maintain its structural integrity for at least a decade.

The secret to weathering steel’s impressive lifespan lies in its unique ability to form a dense, protective layer of oxidation on its surface. This patina acts as a barrier, shielding the steel from further corrosion and deterioration. However, it’s important to note that certain environmental factors can accelerate the oxidation process, potentially impacting the edging’s longevity.
