The structural elements of the parts of the device’s mechanical order, as well as their components,
are made of hot-dip galvanized steel sheets which are painted electrostatically with a polyester base color
of 120 μm thickness, initially subjected to a chemical pretreatment carried out in several stages prior to
dyeing to achieve a high protection of materials and excellent adhesion of the paint to their surface.
The lowest part of the curtain is equipped with a single modular profile, which enhances its
robustness and stability. The bottom bar has applied a high quality EPDM reinforced rubber to ensure
sealing with the floor.
The rotation of the roller shutter’s shaft around of which the curtain is wrapped, is ensured by a
three-phase electric motor to which a suitable gear reducer is fitted. The transmission assembly consists
of the chain, sprockets and scroll bearings (Figure 2).

The halt of the screen at the boundary transport positions is ensured by means of terminal
switches, while for additional safety provision is made for the installation of mechanical terminals.
To avoid uncontrolled downward movement of the curtain, a centrifugal brake is provided to
ensure mechanical locking and immobility (Figure 3). In addition, in order to avoid potential hazards, the
device may be equipped (optionally) with photocells and pressure sensors.
