What Is Corten Steel?

Corten steel is also called weathering steel; it is a set of steel alloys created to remove the need for painting. Over the course of time this material forms a steady rust-like look after exposure to the elements. This oxidized layer protects the metal under it making it perfect for outdoor corten steel planters.

Not like ordinary metals, corten steel ages smoothly, becoming more beautiful over time. This is why designers, landscape designers, and homeowners alike are incorporating landscape corten steel planters into their designs.

Benefits of Corten Steel Planters

  1. Weather Resistance & Durability : One of the main reasons for the increasing recognition of corten steel planter boxes is their remarkable resistance against corrosion. The patina layer that forms acts as a protective layer that means these planters remain for many years in outdoor environments.
  1. Low Maintenance : Once the patina evolves corten steel planters need low maintenance. Not like painted metal planters that chip or fade corten planters preserve their traits without the need for sealing, painting or extra treatments.
  1. Modern Aesthetic Appeal : The warm, earthy tones and industrial texture of corten steel planter walls bring a contemporary yet rustic charm to any setting. Whether you’re using round corten steel planters for outdoor decor or corten steel planters square for structured layouts, the visual appeal is undeniable.
  1. Sustainability : Made from recyclable materials, corten steel planters are an eco-conscious choice. Their long life cycle and minimal maintenance reduce environmental impact compared to plastic or treated wood alternatives.
