XT-300 SELF-LOCKING Roll-Up Door

Roll-up door in extruded aluminum of high strength 6063-T5 alloy (Aluminum, Silicon, Magnesium and Titanium) from the brand PORTALUM Model XT-300. Roll-up door consisting of a curved main profile and an intermediate locking profile. These profiles, thanks to their innovative design, are linked to each other, allowing that when the door lock is completely lowered, the intermediate profile is rotated in the guides, producing an effective lock on both sides of the door and for each equidistance of the main slats that make up the rolling door. This self-locking mechanism of the profiles, without the addition of external mechanisms, provides maximum security against intrusion and burglary in commercial premises, residential garages and industrial closures. The XT-300 model allows a wide range of finishes for the customer’s choice with blind, combined and die-cut versions with or without methacrylate.
