The extension of the original concept of Sinus tree grates has resulted in the creation of several separate outdoor benches with an unmistakable expression. The strong steel sheet, simply bent in a finely trapezoidal profile, is reinforced with an almost invisible rib, rendering a completely solid shape, even for the most extended bench. The perforation refers to the pure aesthetics of the sixties, and when combined with the unique Citépin (plastic plugs), it eliminates the disadvantage of cold metal.
