The answer is simple. Carl Stahl X-TEND is fully load rated. In the case of this enclosure, the structural performance of the mesh allowed the designer to minimize the size and amount of steelwork involved in the structure. In short, the mesh becomes part of the primary load carrying structure, sharing the load and enabling the optimization of other primary structural components.
At Halle Zoo, three lightweight pylons wrapped in X-TEND wire mesh is all that is required to provide a habitat for the marmoset monkeys. Consistent with other more conventional forms of lightweight fabric architecture, the mesh supports the steelwork, holding it in position.
In such a small enclosure, the monkeys have space to swing without fear of injury from contact with structural clutter. Meanwhile, the visitors appreciate the openness of the space and the ability to get closer to the action.
