Global trade and transportation heavily rely on shipping containers which serve as robust metal boxes specifically designed to endure the challenges of long-distance shipping. These standardized containers ensure secure and efficient movement of goods across various parts of the world. However it’s worth knowing what type of metal is typically utilized in constructing these versatile storage units. In this article, we’ll discuss the commonly used metal for making shipping containers and its distinctive characteristics that make it an ideal choice for such purposes.

The Versatile Material

Corten steel, also referred to as weathering steel is a popular choice for shipping containers because of its distinct characteristics and benefits in marine settings. Let’s explore why Corten steel is the preferred option for shipping containers:

Corrosion Resistance: Corten steel possesses remarkable resistance to corrosion, rendering it suitable for long-term exposure to various environmental conditions such as saltwater and humidity. Its composition containing elements like copper, nickel, and chromium contributes towards this quality. A protective oxide layer develops on the surface of Corten steel which restricts any further corrosive damage thereby improving its longevity and sturdiness.
Longevity:Shipping containers are constantly exposed to harsh conditions during transportation and storage. Corten steel’s corrosion-resistant properties contribute to its longevity and ability to withstand the rigors of marine environments. It reduces the need for frequent maintenance thereby extending the life cycle of shipping containers.
Strength and Structural Integrity: The structural integrity of shipping containers is maintained due to the exceptional tensile strength exhibited by Corten steel which enables it to withstand heavy loads and support stacking or lifting through cranes during transportation. Furthermore its high strength to weight ratio proves beneficial in this regard.
Weldability and Fabrication: Corten steel can be easily welded and fabricated allowing for efficient manufacturing of shipping containers. This characteristic simplifies the construction process and enables the creation of containers with various sizes and configurations to meet specific shipping requirements.
Aesthetics: Corten steel develops a distinctive rust-like appearance over time which gives shipping containers a unique and industrial look. This aesthetic appeal has contributed to the popularity of Corten steel in architectural and design applications including shipping container homes and commercial structures.
