A functional design concept is characteristic of this product range of grates for parks. Die-cut steel surfaces create a design unit and allow rainwater to seep through. The surface design unites all structural elements of the range in a distinctive way: the grate decorates the base of the drinking fountain in a delicate and playful manner, while the proportionally enlarged die-cuts at the tree fence have a stringently symmetrical effect. The four-part grate is exchangeable to give more room to growing trees.
