The Emap stand includes four 'nodes'- coloured drumshaped 'enclosure screens' - with white canopies like lotus leaves hovering above them, each supported on a single 454mm diameter CHS column.
Each canopy is oval on plan. A 101mm diameter CHS runs at the perimeter, supported by a steel frame fixed back to the column. The canopy is covered with an upper and lower sheet of Barrisol white pvc-based single-ply membrane. The material was cut to shape and size at the Barrisol factory in France, and a 'harpoon' edge was welded to the perimeter.
The material was cut approximately 7 per cent smaller than actual size and heat-stretched on site between the column and the outer perimeter beam. The harpoon edge clips into curved extruded aluminium profiles fixed to flanges welded to the perimeter beam and to the column. On cooling the edges are secured by the tensile force of the material; they can be unclipped for maintenance.
Barrisol contains titanium for strength and to provide a Class O fire rating. The white matt finish gives 80 per cent light reflection.
The canopy support frame consists of a double ring of beams; the outer perimeter beam - an oval 101mm diameter CHS - and an inner 50 x 50mm SHS circular ring, which are welded together by a series of 50 x 50mm SHS struts. This double ring is suspended from the top of the column by a set of 6mm stranded wire cables, and braced by a similar set of cables fixed to the column at a lower level. The cables are swaged at their ends with eye connectors and are fitted with turnbuckles for adjustment. The eyes are clipped to two steel collars which encircle the column.
