Locally manufactured, Micro-perforated, slat profile, security-rolling shutters are ideal where a high degree of security is required while still maintaining vision.
These shutters are used mainly in Shopping malls, Showrooms, Banks etc. These shutters give virtually the same protection and security as a solid closed type shutter but with vision. When shop/showrooms or window displays are illuminated with shutters in closed position an amazing degree of vision is permitted.
