Composition and manufacture

RHS or UC steel columns, with slab baseplates and top-caps support universal beams, inset with galvanised joists topped with decking to form a highly-rigid, but slimline, floor profile. Many deck material options suit different environments and load requirements up to 10kN/m2. Special design features include bunded and corrosion-resistant decking, portalised connections to obviate stability bracing and improved deflection limitation.


With installation of fire protection, partitions and ceilings, column cladding, balustrade and staircase systems, each mezzanine is finished to the client’s exact application, environment and budget. Space planning, interior design and full fitting-out services are provided for entire schemes.


All design loadings are to BS 6399-1:1984 with BRE Digests to 437 and 477, Building Regulations and BS 5950-5:1998. Modular standard construction comprises regular column grids for economy and load imposition directly on to the concrete slab. Bespoke design solutions with large spans, minimum columns and slab reinforcement tailored to site conditions and client. Up to 2 hours fire protection can be provided to structures in cladding, ceiling or intumescent paint finishes. Fire separation walls, goods lifts and enclosed internal or galvanised fire escape staircases specified to comply with regulations.


Expert planning at the design and production stage enables an extremely fast site build time by crews having unrivalled training, certification and experience in all aspects. Sites include Airbus UK, AXA Technology, B&W Loudspeakers, BAE Systems, Blachere Illumination, Brand Partnership, British Geological Survey, British Vita, Cannon Rubber, Decleor, Disney Store, G Plan Furniture, GIST, HSBC, Inland Revenue, Kerry Foods, Marks & Spencer, Muller Dairies, Nottingham University, Printing.Com, Specsavers Opticians and Vidal Sassoon.
