Storage Units & Site Offices from the expanda range. Expanda store, expanada chem and expanda kabin. All allow you to move your site office as required. Expanda Kabin is a movable office whilst Expanda Chem is for storing hazardous chemicals and fitted with a sump to contain chemical spillage. Expanda Store is a unique portable building ideal for restricted access, remote areas and congested site situations. The units are extended in width or length by adding further modules. There is no maximum size for construction. The components are light enough to be man handled and small enough to fit through a small passageway. Once assembled, the Expanda-Store is remarkably robust, with a new double locking system to deter the most determined thief. All parts can be ordered separately so damaged components are replaceable. Due to the demountability of the product, less space is required when in transit or in storage.
