What are the negatives of Corten steel?
While Corten steel may be visually appealing, its unstable ferro-oxyhydroxide layer, susceptibility to rust and corrosion, limited lifespan, and contamination risks make it an unreliable choice for architectural applications. While Corten Steel Planters bring numerous benefits to the table, one potential disadvantage is their substantial weight. These planters are significantly heavier than alternatives made from materials like plastic, fiberglass, or even some types of wood.However, given Corten’s longevity and lower maintenance needs, it represents a long-term investment. Mild steel is certainly a cost-effective alternative, but if a protective coating, such as powder coating or galvanising, is applied for added longevity, the cost comparison with Corten starts to level out.Unlike stainless steel, Corten Steel is a distinct type of alloy designed to weather gracefully over time, offering structural strength and an aesthetic quality that sets it apart.After installation and exposure to normal weather the surface of the panel develops a gorgeous rustic finish and texture. Corten contains copper, chromium, manganese, and nickel which makes this material more expensive.The appearance of corten steel develops over time and it is normal for it to flake a little at the bottom where there is the most water. This has no bearing on the durability of the corten steel. It’s also important to note that rust is 7 times thicker than the original steel.
What is a cheaper alternative to corten steel?
Mild Steel does not form a protective layer but aesthetically is very similar to Corten Steel. Corten starts to develop its trademark Patina quicker than Mild Steel. Mild Steel is a more cost-effective alternative to Corten for those budget-conscious gardeners. Corten Steel is used today for storage containers, bridges, planters, and more because it doesn’t corrode over time.COR-TEN, Corten, weathering steel, and preweathered steel are all used, often interchangeably, to refer to the rust-hued steel that is used today for everything from bridge structural members to world-class architecture. But there are important differences between these materials.The rusting or weathering process of Corten steel is what makes it special. It does not prevent rusting, but it forms rust only on its outer surface for protection. The presence of chromium, copper and nickel improves the Corten steel’s weather resistance, allowing the development of a desirable patina.To tell you frankly, Corten Steel’s lifespan can reach up to several decades and, in some cases, even beyond a century, around 40-120 years! Yep, you heard it right – Corten Steel is no one-hit wonder. Its durability is a testament to its unique composition and the formation of that protective rust-like patina.Limited Use in Extremely Corrosive Environments Although corten steel has great corrosion resistance, it might not be appropriate for very corrosive situations, such as coastal regions with a lot of exposure to seawater. Additional safeguards or other steel alternatives could be required in such circumstances.
How to tell if steel is Corten?
Corten Steel undergoes a gradual weathering process so that you may notice signs of ageing, such as rust accumulation and colour changes over time. These visual cues indicate that the steel is indeed Corten and not a standard steel with surface rust. As mentioned above, corten steel is very low maintenance. However, we do recommend regular checks and cleaning to make up part of a periodic maintenance schedule. Remove any packaging from the product as soon as the delivery is received. Shrink wrap or other packaging materials may cause an uneven patina.Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.As mentioned above, corten steel is very low maintenance.

Is Corten steel good for planters?
Corten Steel is used today for storage containers, bridges, planters, and more because it doesn’t corrode over time. For this reason, it is recommended sealing the insides of planters and the backs of retaining walls made of corten steel with a bitumen sealer. By following these simple care and maintenance tips, you can ensure that your corten steel structures will last for many years to come.
How long will corten steel last outside?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years. Unlike stainless steel, Corten Steel is a distinct type of alloy designed to weather gracefully over time, offering structural strength and an aesthetic quality that sets it apart.
