Double security door solution
Double door. For a spacious, impressive entrance hall. Gradara is the ideal security door to protect large size entrances. One door is swing. The other is semi-fixed.
The Scrigno Tech line comprises specific solutions such as the Gradara two-door security solution. Large in size like a large portal, it is especially suitable for very large entrances. The asymmetrical version has a small semi-fixed door and a swing door. Various finishes are available: veneered panels, lacquered panels, or steel or aluminium panels. Shatter-proof glass inserts can also be included. This door is certified in burglar-resistance class 3 in accordance with European standard UNI EN 1627-1628-1629-1630. Thermally and acoustically insulated panels are located inside the panel body for greater thermal-acoustic comfort. The door has a thermal transmittance value of between 1.6 and 1.2 w/m²k while its acoustic insulation value is 28 db.
Frame and hinges
The 20/10 thick sheet steel makes up the structure of the security door. Burglar-resistant deadbolts are fitted on the hinge side. There are six tubular hinges. Three for each door.
Lock and accessories
The lock on Gradara can either be a European cylinder or a double cylinder lock. As a rule, the lock has an installer key and five user keys. The security door comes with a variety of handles, external knobs and different-length grab bars.
