AI summary

The present invention relates to a canopy structure comprising a plurality of T-shaped profile members (10) each having a middle flange (12) and two free flanges (14, 16); and a plurality of metal U-shaped profile members (38) each having two opposing flanges (42, 44) extended by two edges (46, 48) folded towards one another. The structure further comprises a plurality of latching U-shaped profiled sections (58) made of polymeric material, each comprising two retaining flanges (60, 62) and two opposing latching flanges (64, 66). The latching U-shaped profiled sections (58) are suitable for being inserted into each of said U-shaped profile members (38) so that said retaining flanges (60, 62) engage with said folded edges (46, 48), while said middle flange (12) engages between said two latching flanges (64, 66).
