Frequently Asked Questions:

How long does it take to put the flat pack Expandastore together?

It takes around an hour to assemble the Expandastore flat pack storage container. For experienced users it should be less, obviously if you are putting it together for the first time it may take a little longer.

Can all of the parts of the flat pack Expandastore be carried by hand?

All of the parts of the flat pack store can be carried by two people except the floor section (chassis) of the 3m and 4m Expandastores which will require more people due to the weight (351kg/421kg).

How many people are needed to put an Expandastore together?

Two people will be able to assemble the Expandastore flat pack store in most instances. If the floor section (chassis) has to be moved form where it is offloaded additional people will be required as above.

Will the flat pack container fit through a standard doorway?

The height of a standard single doorway is too low for the panels to fit through.

How long will my flat pack Expandastore take to be delivered?

Standard delivery as part of a shared load normally takes around 3 weeks but could be much sooner if we are planning a delivery run to your area at the time you order. We will let you know around five days in advance what day the delivery will be made. If you require a specific delivery date or time, or more advanced prior notice please contact us.

How will my Expandastore be delivered?

We normally use a 26 ton rigid HIAB crane lorry that will offload the flat pack storage container directly alongside at curb side so sufficient room for the vehicle to setup and offload will be required on site. Please contact us if you need a non-standard vehicle or method of offloading or any other site specific requirements.

Can the door be fitted in the long side of the Expandastore?

It is possible to order the Expandastore with the door fitted in the long side panel of the flat pack container. This does not incur any additional cost.

Is the Expandastore weatherproof?

Yes, the flat pack Expandastore storage container is designed for exterior use in all weather conditions and if properly assembled will is fully weather proof.

Can I get my Expandastore in a different colour?

As well as the standard galvanised finish and green, blue or grey exterior powder coating, the Expandastore flat pack container can be supplied in other colours from the RAL colour system depending on availability.
