ABSTRACT:
The present invention relates to a tubular section which may be constructed from a sheet having a pair of opposed edges. The opposed edges are releasably connectable such that the section may be stored in a relatively flat configuration. The screw fasteners used to connect the edges together may be restrained from rotation using for example a stringer element appropriately stabilised relative to the fasteners.
