The “Siegen” series fulfills many purposes particularly economically. The base system is focused on the essentials: a galvanised tubular steel construction on which the pent roof lies with weatherproof trapezoidal sheet metal roofing. Trapezoidal metal sheeting or polyester are available for the sides. The rear can consist of trapezoidal sheet metal. “Siegen” can be combined with extension units in a variety of ways so that roofs of different shapes and sizes are created. For weatherproof storage of material or for parking motor vehicles, bicycles or construction machinery. Kit for self-installation and for bolting down.
