Depending on the perspective, expanded metals offer views into or out of the building. Due to their three-dimensional character, they score with significant strength and surface stability. In contrast to perforated metal sheets, the production is waste-free, therefore expanded metals are often the more cost-efficient alternative.
Expanded metals are defined by openings in the surface, caused by staggered cuts, which are created by means of expanding deformation and without any loss of material. Expanded metals are made of sheets or strips, the resulting mesh is neither plaited nor welded.
Expanded metals are usually made of metal, but they can also be made of plastic. Produced in standard production, expanded metals display ribbed, plastically structured surfaces, while flat rolling of the grating is found in perforated metal sheets. Expanded metals can achieve free cross sections between 4 and 90 percent; In contrast to perforated metal sheets, however, there is no waste during production (cut punching). Expanded metal gratings exhibit significant strength and surface stability, as stretching (“cold drawing”) causes metals to become brittle and become more resistant to bending. Due to their 3-dimensional character, façades made of expanded metal turn into “eye catchers”.

The expanded metal façade is used as sun protection but is also “interwoven” with flower pots whose design follows the form of the existing building and joins it to the new expansion. The façade unifies the entire building by connecting the old construction with the new extension.
