What elements are included in the design of protective rolllets
By the design of the roller shutters (rollelet systems), somewhat reminiscent of ordinary window blinds. The mobile part is a canvas formed by strong steel or aluminum horizontal profiled stripes, which “come together” and “move out” like blinds. A winding device equipped with a manual or electric drive is located in a small box that is mounted above the opening.
The perimeter element of the rollet is a compact rectangular metal frame attached to the outer surface of the wall along the perimeter of the closed opening. Additional protection is provided by strong shutters that can be located both inside and outside the room. It is amazing that all this complex design at first glance looks completely not bulky, but, on the contrary, stylishly and noble.
