The thinnest armoured door on the market

A product line that is renewed in its look confirming its performance.
The revolutionary thickness of the door guarantees maximum safety and lends itself to a variety of uses. It is ideal for protecting the privacy of offices or premises, wherever sensitive data is present.

Minimal design

The new squared edging strip in just 1.5 cm frames the door like a contemporary painting welcoming you at the entrance.

The door design is further enhanced by the exclusive square handles with glossy or satin finishes.
