Green wall consists of a series of steel cultivation tubs of any desired length. The tanks are joined together to form a monolith without intermediate walls. Green wall can be free-standing, fixed to the ground or to a wall, even just on one side. In the case of a self-supporting Green wall, this can be single-sided, when the plants emerge only on one side, or double-sided, i.e. on both sides. In the case of wall mounting in modular compositions, uprights allow fixing. These tubs can be mounted in series and obtain a dense covering of plants, or spaced out, and in this case a wire mesh can be mounted as a trellis to support the ground cover plants. A multifaceted system, designed and developed to carry out articulated projects, and customised in terms of shape, size and performance.
