What Grade of Steel is Used in Shipping Containers?
Shipping containers have become a popular option for a variety of purposes, including storage, housing, and transportation. They’re sturdy, durable, and can withstand harsh weather conditions. However, not all shipping containers are created equal, and the grade of steel used in their construction can vary. In this blog post, we’ll explore the grade of steel used in shipping containers, its properties, and its suitability for various purposes.
What is Steel Grade?
The steel grade is a classification system used to describe the quality and characteristics of steel. The grade of steel used in a shipping container is an essential factor to consider, as it can affect the container’s durability, strength, and ability to withstand harsh conditions.
What Grade Steel is Used in Shipping Containers?
Shipping containers are typically made from corten steel, also known as weathering steel. Corten steel is a high-strength, low-alloy steel that contains copper, chromium, and nickel. The steel is designed to form a protective layer of rust when exposed to weather conditions, protecting it from corrosion and rust. Corten steel is a type of steel that meets the following specifications:
- ASTM A242 – This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight or added durability are important.
- ASTM A588 – This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight or added durability are important.
- ISO 6346 – This is the standard for the coding, identification, and marking of freight containers used in the international intermodal freight transport industry.
Properties of Corten Steel
Corten steel has several properties that make it ideal for use in shipping containers, including:
- High Strength – Corten steel is a high-strength steel that can withstand harsh weather conditions and resist corrosion.
- Corrosion Resistance – Corten steel forms a protective layer of rust when exposed to weather conditions, protecting it from corrosion and rust.
- Low Maintenance – Corten steel requires minimal maintenance and upkeep, making it a popular choice for shipping containers.
- Longevity – Corten steel has a long lifespan, making it a durable and cost-effective choice for shipping containers.
Suitability for Various Purposes
Corten steel is an ideal choice for shipping containers due to its strength, corrosion resistance, and longevity. It can withstand harsh weather conditions and resist corrosion, making it suitable for use in transportation and storage. Additionally, its low maintenance requirements and long lifespan make it a cost-effective choice for businesses and individuals looking for durable and reliable storage solutions.
Corten steel is the grade of steel used in shipping containers due to its high strength, corrosion resistance, low maintenance requirements, and longevity. It can withstand harsh weather conditions and resist corrosion, making it an ideal choice for transportation and storage purposes. When considering purchasing or repurposing a shipping container, it’s essential to consider the grade of steel used to ensure it meets your requirements for strength, durability, and longevity.
Aluminum vs Steel Shipping Containers
While steel shipping containers are the most commonly used type, aluminum shipping containers are also available. Both materials have their advantages and disadvantages, and it’s important to consider which one is the best fit for your needs.
Aluminum Shipping Containers
Aluminum shipping containers are less common than steel containers, but they do have some advantages:
- Lightweight – Aluminum is much lighter than steel, which means that aluminum containers can be easier to move and transport.
- Corrosion-Resistant – Aluminum is naturally corrosion-resistant, which means that aluminum containers won’t rust and can withstand harsh weather conditions.
- Low Maintenance – Aluminum requires very little maintenance, which can save time and money in the long run.
However, aluminum containers also have some disadvantages:
- More Expensive – Aluminum is more expensive than steel, which means that aluminum containers can be more expensive to purchase or rent.
- Less Durable – While aluminum is strong, it’s not as durable as steel, which means that aluminum containers may not last as long as steel containers.
- Not as Secure – Aluminum is less secure than steel, which means that aluminum containers may be easier to break into or vandalize.
Steel Shipping Containers
Steel shipping containers are the most commonly used type and have been around for several decades. They have several advantages:
- Durable – Steel is stronger and more durable than aluminum, which means that steel containers can withstand harsher conditions and last longer.
- Secure – Steel containers are more secure than aluminum containers, which means that they are less likely to be broken into or vandalized.
- Cost-Effective – Steel is less expensive than aluminum, which means that steel containers are typically more affordable than aluminum containers.
However, steel containers also have some disadvantages:
- Heavy – Steel is heavier than aluminum, which means that steel containers can be more difficult to move and transport.
- Corrosion – Steel is prone to corrosion and rust, which means that steel containers can deteriorate over time if not properly maintained.
- Maintenance – Steel requires regular maintenance to prevent corrosion and rust, which can add to the overall cost of the container.
When choosing between aluminum and steel shipping containers, it’s essential to consider your specific needs and requirements. Aluminum containers are lightweight, corrosion-resistant, and low maintenance, but they are also more expensive and less durable than steel containers. Steel containers are durable, secure, and cost-effective, but they are heavier and require regular maintenance to prevent corrosion and rust. By considering these factors, you can choose the best type of container for your needs and ensure that you are getting the most value for your investment.
How Much Do Shipping Containers Cost?
The cost of shipping containers can vary depending on several factors, including the condition of the container, its size, and its location. In this section, we’ll explore the different factors that can affect the cost of shipping containers and provide a rough estimate of what businesses or individuals can expect to pay.
Factors That Affect the Cost of Shipping Containers
- Condition – The condition of the container is one of the most significant factors that can affect the cost. New or nearly new containers will be more expensive than used containers, which may have some wear and tear.
- Size – The size of the container is another significant factor. Standard-sized containers, such as 20-foot and 40-foot containers, are typically more affordable than larger or custom-sized containers.
- Location – The location of the container can also affect the cost. Containers located in areas with high demand or limited supply may be more expensive than containers located in areas with more availability.
- Customizations – Customizations such as doors, windows, or insulation can add to the overall cost of the container.
- Delivery – The cost of delivery can also add to the overall cost of the container. Containers that are closer to the buyer’s location will typically be less expensive to deliver than containers that are located further away.
Estimated Cost of Shipping Containers
The cost of shipping containers can vary widely depending on the above factors, but here is a rough estimate of what businesses or individuals can expect to pay:
- New 20-foot container: $3,000 to $5,000
- New 40-foot container: $4,000 to $7,000
- Used 20-foot container: $1,500 to $3,000
- Used 40-foot container: $2,000 to $5,000
Shipping containers are a cost-effective solution for storage, housing, and transportation. The cost of shipping containers can vary depending on several factors, including the condition of the container, its size, and its location. By considering these factors, businesses or individuals can estimate the cost of shipping containers and choose the best option for their needs and budget. With the right shipping container, businesses or individuals can benefit from durable, secure, and reliable storage or transportation solutions.
