How are the containers delivered?

Containers are delivered by truck, either tilt-bed or flatbed. A tilt-bed truck allows the container to be positioned on the ground at the delivery location. Delivery by flatbed truck generally costs less than by tilt-bed, but requires that you have the proper machinery to lift the container off the truck at your site. For container purchases, Interport can arrange delivery through one of its third-party trucking providers or you can engage the trucking company of your choice to pick your container up at Interport’s depot. For container rentals, Interport will arrange delivery through one of its third-party trucking providers. 

How should I prepare the ground for delivery?

Your container should be placed on firm, dry, level ground, i.e. pavement, gravel, or hard dirt.

How much room is required for tilt-bed delivery?

For a 20’ container: 60’ of straight running room; for a 40’ container: 110’ of straight running room.

How can my container be customized?

Interport can add personnel doors, roll-up doors, or windows, and can paint your container. Other customization options are also available.

How is payment made?

Once you’ve ordered your container, Interport will issue you an invoice. Once your invoice is paid via check, money order, wire transfer, cash, or credit card, Interport will release your container to you or to the trucking company making your delivery.
