Trading Ethos

We pride our self in trading in an ethical and supportive manner no matter how small or large the project and offer our products on a 'supply only or fully installed basis.


3CB have recently completed 4 pitch side canopy and training room units for a prestigious new sports facility under construction in the West of England. The design brief was originally for conventional steel buildings constructed on site. However we felt we could offer a lower cost and more attractive solution, both externally and internally, by designing and manufacturing pre-constructed and clad units which could be lifted onto site and subsequently timber clad in a fire resistant treated timber as specified by the architects. The project also incorporated a larger general storage building, again timber clad in a fire resistant tongue and groove board.​


3CB were commissioned to obtain planning and undertake a total turnkey solution for this prestigious group. The group had to vacate its previous storage facility due to a housing project and establish a very large new store in a comparatively short period. The building itself at 27m x 47m x 11m was installed after demolition of an existing aged facility that was neither tall enough nor water tight. 3CB’s galvanised hot rolled steel solution was designed precisely to the clients specification to achieve a high level of racking density and thereby maximise use of the floor area. After completion 3CB installed a sophisticated automated lighting system and fire alarm. 3CB completed the project to the requested time frame and the client was delighted with our overall quality of performance and of the building also. Click the photos below to view the construction timeline ...​


3CB recently undertook the design, supply and hazardous installation of a complex air entrainment building within a very large waste water treatment facility in the East Midlands. Time lines and working methodologies were tight. Working for a well-known and respected national main contractor on this project, and the successful completion of the work undertaken by 3CB, has led to further significant project work since - including new build and refurbishment work.​
