What Is a Flat Rack Shipping Container?

A Flat Rack shipping container is a specialized freight container with a reinforced steel floor and end walls but no fixed side walls or roof. This design allows cargo to extend beyond the width or height of the container when necessary, making Flat Rack containers ideal for oversized shipments.

They are commonly used in international shipping, construction, manufacturing, mining, and energy industries where conventional containers cannot accommodate the size or shape of the cargo.

Customers often compare Flat Rack Containers with Open Top Containers. While Open Top containers allow loading from above, Flat Rack containers provide unrestricted side access for exceptionally wide or oversized loads.

Standard Dimensions of Flat Rack Shipping Containers

Flat Rack containers are commonly available in two standard sizes:

20ft Flat Rack Container

• Exterior Length: 20 feet
• Exterior Width: 8 feet
• Maximum Payload Capacity: Designed for heavy equipment and machinery
• Reinforced steel floor
• Fixed or collapsible end walls

40ft Flat Rack Container

• Exterior Length: 40 feet
• Exterior Width: 8 feet
• Increased cargo capacity
• Heavy-duty steel construction
• Suitable for oversized industrial shipments

Their standardized dimensions allow them to integrate seamlessly into global shipping and logistics networks.

Benefits of Flat Rack Shipping Containers

Perfect for Oversized Cargo

Flat Rack containers can safely transport equipment and materials that are too large for standard enclosed containers.

Easy Loading and Unloading

The open-sided design allows forklifts, cranes, and other heavy equipment to load cargo from the sides or above with ease.

Heavy-Duty Construction

Manufactured from high-strength corten steel, Flat Rack containers are built to handle extremely heavy loads while maintaining structural integrity.

Flexible Transportation

Flat Rack containers are suitable for road, rail, and ocean transport, making them an excellent choice for international logistics.

Cost-Effective for Large Equipment

Using a Flat Rack container can simplify transportation for oversized cargo, reducing the need for specialized shipping arrangements.

Common Uses for Flat Rack Shipping Containers

Flat Rack containers are widely used across numerous industries.

Typical applications include:

• Construction machinery
• Agricultural equipment
• Mining equipment
• Industrial generators
• Large pipes
• Steel beams
• Wind turbine components
• Boats and yachts
• Heavy vehicles
• Manufacturing equipment

Businesses transporting tall cargo may also consider our Open Top Containers, while customers needing secure enclosed storage should explore our 40ft Shipping Containers or High Cube Containers.

Flat Rack vs. Standard Shipping Containers

Understanding the differences can help you select the right container for your project.

Flat Rack Containers

• Open sides
• No fixed roof
• Ideal for oversized machinery
• Crane and forklift loading
• Suitable for extra-wide cargo

Standard Shipping Containers

• Fully enclosed
• Better weather protection
• Ideal for general cargo
• Maximum security
• Excellent for long-term storage

The best choice depends on the dimensions and loading requirements of your cargo.

New vs. Used Flat Rack Containers

A new Flat Rack container offers maximum structural integrity, minimal wear, and the longest service life, making it ideal for frequent commercial use.

A used Flat Rack container provides a more economical solution while still offering excellent performance for many transportation and storage applications.

For general-purpose storage, many customers also choose our Used Shipping Containers.

Delivery and Installation

Before purchasing a Flat Rack container, ensure your delivery site has adequate space for unloading heavy equipment. Because these containers are often used with cranes or forklifts, sufficient working space is essential.

A level, stable surface helps support the container and ensures safe loading and unloading operations.
