Fassadengrün sells stainless-steel trellises along with their attachments. Due to their rigidity, steel trellises can also be used with externally insulated walls! There is an inexhaustible diversity of shapes, designs, and materials available, even for small wall grids. You will find examples of all kinds of trellises in this section. In the following section, you will see examples of larger trellis grids, so-called "mesh panels" (used often for wire fences).
Metal trellises usually have the shape of a "standing rectangle," the upright position corresponding to the growth of the plants. The irregular lines of the plants contradict the severe lines of the trellis and the façade. The overall picture of the "green wall" that emerges between the strict lines is very harmonious ... the rectangular shape is a very strong design element for wall trellises!
Inside the frame, the grid mesh can be made of squares or rectangles; those can be arranged evenly or as is the case with our trellises, be a little more dense in the middle.
Our trellises are made of stainless steel and are thus corrosion free. The trellises are galvanically 'washed' and are therefore free of impurities or foreign bodies that can appear during the spot-welding process. One can find inexpensive stainless steel versions-- "raw" or unwashed-- which are not cleaned galvanically (for example, in garden furniture and reinforcing mats), but such grids are not sufficiently corrosion-resistant for the greening of facades.
Galvanized grids can last for several decades outdoors, depending on the situation on site. Steel trellises with a plastic coating often corrode only after 5 years... Some trellises are deliberately produced with rust to emphasize an "antique" style!
Fan-shaped trellises bring in a third language of form (a new diagonal) on the facade. When they are placed next to a window, they can disrupt the harmonic contrast between the shape of the plant and the grid lines of the building, causing visual confusion, or the eye of the observer to be somewhat irritated. For this reason, fan-shaped trellises should be used on windowless facades, if at all.
