1. Should I hire or buy a multidoor container?

Hire suits operators trialling additional storage capacity, while buying is the better option for self-storage sites looking to add a permanent, revenue-generating asset. Willbox offers multidoor containers for hire or purchase in 20ft or 40ft sizes.

2. How many storage bays does a multidoor container have?

A 20ft multidoor unit is divided into 4 individually lockable bays, while a 40ft unit offers 8 bays, letting you maximise revenue from a limited footprint. Each bay has its own 10-point security door for independent access.

3. Are multidoor containers secure enough for customer storage?

Yes, each bay features a 10-point security door with rubber grip handles, and the units are built with 10% extra steel weight for added durability. This makes them a robust choice for self-storage operators renting out individual bays to customers.

4. Can multidoor containers be customised for my site branding?

Yes, they're available in green or blue as standard and can be customised to match your site branding. Willbox's in-house conversions team can also build multidoor units to bespoke specifications beyond the standard off-the-shelf product.

5. What condition features help multidoor containers stay in good shape?

They include dark bamboo flooring for easy cleaning and additional vents to reduce condensation, minimising the need for Grafo Therm treatment. This helps keep individual bays dry and in good condition for tenants' stored goods.

6. What should I know about delivering a multidoor container to a self-storage site?

Multidoor units are built with 10% extra steel for durability, so they're heavier than a standard container of the same size, and delivery is typically by HIAB or flatbed with the same access and level-base requirements. If you're planning to stack units or expand your self-storage layout in future, it's worth discussing site positioning with Willbox in advance.
