Auto-locking security rolling shutters

Sistema de seguridad antirrobo para persianas enrollables

The Portalum auto-locking security rolling shutters are a highly recommended solution to achieve a high level of security in the shutters of a house (especially compared to traditional shutters). An intermediate locking profile between the slats prevents the forced lifting of the shutter. Due to its size, it fits perfectly into small gaps and has the highest rating in wind resistance tests. The auto-locking security shutters include a system of intermediate rods that exert pressure on the guides. This action makes it impossible to force the shutter vertically from the outside, and therefore, to access.

When the shutter is down, the locking profile or the rod exerts pressure on the guide, thus preventing the shutter from being lifted by pushing it from the bottom. Available slats: 39 and 45mm with the option of inserting micro-perforated slats to provide light and air circulation. The auto-locking security rolling shutters are usually installed in the façade openings that are most accessible or most likely to be forced (usually on the ground floor) while keeping traditional shutters on the rest of the doors and windows that are difficult to access from the outside. Since the aesthetic is similar, the auto-locking shutters do not disrupt the harmony of the rest of the façade.
