40ft Standard Tunnel Shipping Container

The 40ft standard tunnel shipping container is a modified dry cargo container featuring cargo doors on both ends, enabling access from either side. This configuration is commonly used in logistics, warehousing, and construction applications where efficient loading, unloading, and material flow are required.

Key Features

• Cargo doors at both ends for through-access and simplified inventory management

• Corten steel construction for structural integrity and corrosion resistance

• Marine-grade plywood flooring over steel cross-members

• Lockable doors on each end with locking bars

• Forklift pockets for ease of handling and positioning

• Ventilation openings for airflow and moisture reduction

• Corner castings for lifting and stacking compatibility

Detailed Description

The 40ft tunnel container is constructed from Corten steel, a weathering steel grade that forms a stable protective oxide layer when exposed to atmospheric conditions. This material provides structural integrity and resistance to corrosion, making the container suitable for outdoor placement.

The defining feature of this container is its double-door configuration, with a full set of cargo doors at both ends of the unit. This design enables access from both ends, facilitating “first-in, first-out” inventory management and allowing loading or unloading operations to be performed from either side . The dual-door access eliminates the need to unload the entire container to reach goods stored toward the rear .

The floor system utilizes marine-grade plywood panels secured to steel cross-members, providing load-bearing capacity for palletized goods, equipment, and industrial materials. The container includes corner castings at all eight corners for lifting and stacking compatibility with standard handling equipment . Forklift pockets are positioned along the container base, allowing repositioning with standard forklift equipment.

Each door set includes steel locking bars with a secure locking mechanism compatible with padlocks or security seals. Ventilation openings promote airflow and reduce moisture accumulation.

Intended Use

This container is suited for the following applications:

• Warehousing and logistics operations requiring dual-end access

• Vehicle transport allowing drive-through loading and unloading 

• Construction sites as pedestrian tunnels or secure material storage 

• Industrial partitioning where the container can be divided into two storage compartments 

• Commercial storage requiring quick access to goods stored at either end

The tunnel configuration is particularly suited for operations where cargo must be accessed from both ends, as it enables faster loading and unloading compared to standard containers .
