Standard Container Storage Units

Mr Box specialises in supplying containers for the self store industry. We are members of the Self Storage Association and supply containers to over 30 existing self store clients.

Specification

We source our new containers directly from the factories and build our containers to a specification designed for self store operators. Available in 4 standard sizes at 8 foot long by 7 foot 6 inches high, or 10, 20, or 40 foot long by 8 foot wide, and 8 foot 6 inches high. The most popular containers for storage purposes are the 10 and 20 foot units, as well as the multi-compartmental conversions we offer.

The stores are constructed from corten steel, which is very strong and also resists corrosion. Containers are coated with a 2 pack paint system that is designed to stand up to the rigors of marine use with the underside being bitumen coated.

Additional Mr Box features include:

  • Built to a full marine specification – manufactured from corrosion resistant corten steel.
  • Protected with marine grade paint.
  • Fitted with additional ventilation – to ensure condensation is not a problem.
  • Fitted with high locking bars – for ease of use.
  • A wipe clean 28mm marine ply floor that is specially sealed and certified as being rot and vermin proof.
  • Factory fitted lock box (high security lock box) with anti-jemmy lugs fitted to the doors – which shrouds the padlock and protects it from interference.
  • Available in a range of colours.
  • Capable of being stacked.

We hold stocks of new containers in a variety of colours, although the green and blue are more or less standard.

Tunnel Containers

Most standard containers have double doors on one end, but we also supply tunnel units with doors on both ends. This means the interior can be divided into smaller individual units by placing a movable dividing wall.

Multi-Compartment Storage Unit

Multi Compartment Container Storage Units

Mr Box has developed a design of multi-compartment containers, whereby we adapt standard containers and subdivide them into smaller individual stores. Each unit has its own high security entry door and ventilation. Individual store sizes can vary but up to 8 x 50 units can be achieved in a standard 40ft container. The doors are prefabricated high security personnel doors and are equipped with a multi-lever security locks and anti-jemmey flanges. Not only are they smart and easy to operate, but they are also very secure. This style of container offers a lot of flexibility and normally attracts a better rental return than the standard sized containers.

Padlocks

We also supply special high security padlocks designed for use with a lock box. These locks can be supplied with a master key service whereby you have a key that fits any lock in the series but your client can only access their own container. This enables you to over lock the store should you face any payment problems.

Licence to Store Goods

Self Storage Association

If you are an existing self-store operator, or just in the process of planning a self-store start up, you may find a copy of our Licence to Store Goods useful. Take a look and if you are interested in obtaining an electronic copy give us a call.

Staircases

Containers can be stacked and many of our self-storage customers operate their sites in this fashion. Access to the upper tier of containers can be easily achieved through a mobile staircase. Manually operated or motorised versions are available.

Advice

The self-storage industry is a relatively new and entrepreneurial industry and many of our existing self-store customers were new start up companies when they first approached Mr Box for equipment.

Over the years we have advised many customers on setting up their sites and now pride ourselves on, not just providing containers, but a whole range of complimentary services such as: advice on self-store sites, security and padlock design, master key services, staircases and gantries, and the terms and conditions under which they offer their service.

If you are interested in starting a self-store operation, or are looking for self storage facilities in the UK, please feel free to call us for a chat and we’ll try to assist.
