Why Choose a 20 ft Shipping Container
Dual door sets make loading, unloading, and organizing much easier, especially when you need frequent entry from either direction.
Being able to open both ends creates a clear path for forklifts, pallet jacks, and long materials, improving efficiency on job sites or in warehouses.
Perfect for renovations, job sites, inventory storage, equipment, or household overflow.
Pipes, lumber, scaffolding, and oversized equipment are easier to store when you can access them from either side.
If you load and unload frequently, having two access points saves time and reduces the need to reorganize the entire container.
A new 20 ft Tunnel container is built to last 15–25+ years, giving you reliable storage without the cost of building a permanent structure.

Prepare For A Smooth Delivery
To prepare for a hassle-free delivery, consider these following points:

- Straight line space needed:
- 75ft – for 1 x 20ft container
- 120ft – for 1 x 40ft container or 2 x 20ft (moved together)
- Check the weather conditions
Weather conditions such as rain or snow can impact delivery. Ensure that the path and container location are dry and firm. - Solid, level ground
Containers need to be delivered on solid, level ground to ensure the doors will open and close properly. - Flat delivery site
It is important that the path leading to the delivery site is a level, flat surface as hills and slopes may cause the tilt body truck to get stuck.
