Abstract: A canopy structure 50 a plurality of support posts 11, 12, 13, 14 arranged substantially in the form of an array 51, and a plurality of panels 10 mounted on the support posts to form a canopy cover 50. Each panel 10 is a rectangular sheet of flexible material 16 and a plurality of substantially inextensible support straps 17, 18, 19, 20 fixed to the sheet 16. A support strap extends along each side of the sheet 16. Each end of each support strap is mounted to a support post and an intermediate point is attached to the support strap of an adjacent panel. The support straps generally have a twin catenary configuration which draws fabric from the inner area of the panel towards the edge thereof. The panels are attached to the support posts and to each other by loops of webbing 30, connecting rings 31, and shackles. The loops of webbing 30 are typically reinforced to reduce the likelihood of failure thereof. A canopy panel 10 for use in the canopy structure described above is also included.
