The external protective shutters (roller shutters) can be opened and closed manually (on a rope), with a spring mechanism or an electric drive. The shutters can also be equipped with a lock and/or an anti-burglary system.
The cost of protective shutters depends on the size of the fabric, the chosen control option, and the complexity of installation.
Protective shutters are easy to operate, have a low cost, and a long service life even with intensive use. The main elements of all roller shutter models are: a flexible fabric that winds onto a shaft located above the opening in a protective box.
