Fixed shade sail

Abstract

A fixed shade sail has a tarpaulin on which a lower face and an upper face are identified, a plurality of anchoring bodies connected to the tarpaulin along a peripheral edge of the tarpaulin, and a plurality of main tie-rods connectable to the anchoring bodies for tensioning, in use, the tarpaulin between a plurality of supports directly or indirectly anchored to ground. The fixed shade sail has at least one secondary tie-rod of flexible type arranged at the lower face and directly or indirectly anchorable to the tarpaulin close to or at two ends of the secondary tie-rod. A length of the secondary tie-rod is adjustable through tensioning devices so that the secondary tie-rod is taut between two different portions of the tarpaulin until the secondary tie-rod adheres to the lower face, passes at least close to a central area of the tarpaulin and acts as support for the tarpaulin.
