Material Properties of Weathering Steel

Corten steel is a durable steel that develops a protective layer of rust that is self-sealing - a layer of rust that resists corrosion at a deeper level. Different from ordinary steel, patina is created purposefully and is functional, not a defect.

Weathering performance makes Corten steel perfect for a wide range of climates, regardless of whether you live in coastal areas with lots of rain, deserts, or snowy mountainous regions.

Life Expectancy of Corten Steel Planters

Expected to last 25-40 years

When properly installed, Corten planters will last 25 years or more with no structural deterioration during normal outdoor environments.

Factors Affecting Durability

• Climate and Humidity: If not managed properly, excessive freeze-thaw conditions or waterlogging can shorten service life.

• Drainage Design: Planters must be properly drained to prevent water from pooling at the bottom.

• Soil Type and Moisture: Acid soils can accelerate erosion; the use of a liner should be considered.

• Mounting Surfaces: During early phases of corrosion, avoid putting planters directly on absorbent surfaces (wood decks, concrete without a barrier).
