Corten Steel vs Mild Steel: What’s the Difference

Corten Steel vs Mild Steel

When it comes to metal and steel, the two most popular options are corten steel and mild steel. While both have their unique properties, they also share some similarities. In this blog post, we will take a closer look at the differences between these two materials so that you can make an informed decision when selecting one for your project.

Difference Between Corten Steel and Mild Steel

The main difference between corten steel and mild steel is the amount of carbon in each material. Corten steel has a higher carbon content than mild steel. This makes corten steel more durable and corrosion-resistant than its mild counterpart. Additionally, corten steel is more resistant to extreme temperatures, making it ideal for outdoor applications where the temperature fluctuates throughout the year.

Mild steel has a lower carbon content than corten, which makes it softer and more malleable. Its low carbon content also makes it less resistant to corrosion than corten. However, mild steel does not require special maintenance or treatment to maintain its integrity over time – just regular cleaning is sufficient. This makes mild steel ideal for indoor applications where temperature control is essential.

Uses of Corten Steel vs. Mild Steel

Corten’s superior resistance to corrosion makes it ideal for outdoor use, such as sculptures, building façades, fences, cladding, roofing panels, bridges, and other structures exposed to harsh weather conditions (e.g., snow or sea salt). Additionally, its resistance to extreme temperatures allows it to be used in industrial settings such as furnaces or boilers without worrying about high heat exposure damage over time.

Mild steel’s malleability makes it ideal for indoor use, such as furniture frames or kitchen appliances, where flexibility is important for design purposes. Its low carbon content also means fewer health risks are associated with its use indoors compared with other metals like lead or copper when exposed over long periods due to its non-toxic nature.

Corten steel Vs Mild Steel Price 

The price difference between corten steel and mild steel can be quite significant depending on the specific product. Corten steel is a unique metal made up of alloying elements that resist corrosion while maintaining strength and durability. Since it is more expensive to source and manufacture, corten steel tends to cost much more than its mild steel counterpart. For large-scale industrial uses, such as structural framing or outdoor sculptures, this additional cost may be well worth investing in due to its superior longevity. Furthermore, when used for smaller items like outdoor furniture or décor pieces, corten steel may still be an option if the desired aesthetic is one that will last for years despite a higher initial investment.


Both corten steel and mild steel offer distinct advantages depending on the application you need; however, they both share some similarities. It is important to weigh all factors before selecting one material over another in order to ensure you get the best results possible from your project while staying within budget constraints if necessary. Metal and steel industry professionals should consider both options carefully before making a final decision on what material will work best for their particular application needs, taking into account factors like cost efficiency, durability, flexibility, and health considerations when doing so!
