The basic unit is 10m long, with wind bracing bays at each end. This can be added to in sections of one bay, and can thus be extended to any length as required. In the case of any length over 40m an additional braced bay would be required.

Maximum spacing between wind bracing bars : 6 bays.

 

The marquee framework can either be erected on steel footplates or on hoecker flooring systems. The anchoring method depends upon structural calculations. The structure is assembled from ground level upwards, so no dangerous roof work is involved!

 

The rafters have keder tracks for the PVC sheet keder edges to be inserted, thus resulting in a very tight and secure join between the framework and the PVC sheet.

 

Walls: Keder edges, sliders at top edge for keder tracked eave and gable purlins, laced at centre, white as standard, other colours avaliable upon request.

 

The marquee can be supplied with tested structural calculations. According to structural calculations it is stable in structure to BS6399 pt2 (Wind) & BSEN 1999 Eurocode 9. Design of aluminium structures.

 

Snow must be cleared from the roof regularly or a constant temperature of 12 degrees C must be maintained at the ridge point.
