The right combination between the technical section of used profiles and the use of combined system of special rails and anti-storm hooks, make these roller shutters ideal for installation where a special withstanding against wind pressure is required, also in case of big and XL-Closure.
In relation to the model, the typology of these roller shutters may be realized in extruded aluminium (with a special reinforced section for the WINDoor model) or in different materials, like the double-wall system of DP110 model, in which inside is made with insulated material, in order to ameliorate the temperature and acoustic difference from outside and inside.
