Containers for Exhibition Use
Within the field of unusual requests we were asked to supply and were happy to oblige with 40ft containers to the Ford Motors stand of the 2004 Motor Show at the NEC (the Thunderbird theme). The units were subsequently also used for the Paris Motor Show. We worked with the customer to paint the units a suitable colour that was then specially lit on the stand.

Control Unit Containers
This unit was to container electrical equipment cabinets, so we installed Unistrut in the floor and around the walls for secure fixing of the units, given that these also had to withstand the dynamic forces associated with transportation. We also supplied forced ventilation with plenum mounted fans in order that heat generated by the units could be expelled.

A-Frame Container Unit
The customer wanted the versatility of a 20ft container and a hook-lift A-frame so we combined the two. This unit has a permanently welded A-frame chassis attached to it. If a customer needs to be able to separate the two we can supply an A-frame platform with twistlocks that a container would attach to in the same way as to a vehicle trailer.

Process Enclosure Container
Process enclosure incorporating two lifting beams allowing heavy equipment to be handled for servicing, etc. Exact positioning of various apertures for connections of the process equipment to external systems meant that a complex roof framework was required for the mounting of the beams in exactly the correct position for lifting. High ventilation throughput with fans.

Site Office Containers
A very common request is to convert containers to site offices, mess room, or storage cabins. Armoured and normal personnel doors are commonly fitted into the sidewalls of the container. However, in the example below the customer decided to use the original doors for security and had an internal bulkhead fitted just behind them, with a wooden internal door.

Our Role In Your Project
Whether you require a basic sports club changing room, living accommodation or a highly modified, attenuated, thermally lined, temperature controlled unit with apertures and gland plates galore, we see our role as the provider of a finished product ready to use or receive your equipment/ process/ control panels, without needing further modification by you.
We want to get involved in your project, so we will ask a lot of questions to ensure that all the product related issues have been correctly dealt with (such as structural loading and integrity) and also ensure other specialist features have all been thoroughly thought through and designed.
