Frame marquees use a semi rigid frame to provide structural stability, and mostly use synthetic fabrics as a covering to avoid the problems created by shrinkage and expansion of natural fibres. Frames can be of wood, steel or aluminium tubing or, as is the case with most modern frames, box section aluminium. This latter type are often referred to as "clear span" structures which have no intermediate pole supports.
The uninterrupted internal space of frame structures makes them very popular for a wide variety of events from private functions, through corporate hospitality to large exhibitions.
Because they have a solid frame this type of marquee can accept a higher level of accessories, such as doors, windows, rigid side panels and sophisticated flooring systems. Often guests do not realize that they are actually in a "marquee".
