SDZ system, commonly known as the traditional roller shutter system, is mainly intended for use in existing buildings. This is the perfect solution in case of renovation, when the old roller shutters need to be replaced. Also, this system is often used in newly constructed buildings. At the building’s design stage, architects provide the opportunity to replace roller shutters after years of operation. Specially designed SDZ system allows to quickly et noninvasively install the product to the existing surface. Aluprof offers many construction variants of the system, depending on the components used to match the functionality of the roller shutter and its mode of installation. Roller shutter’s curtain consists of profiles made of high quality sheets covered with two-layer PU/PA paint coatings that are highly resistant to abrasion and weathering. There is also an option to use the PVC profiles.
