1. What do we mean when we speak of ‘Class’ in a reinforced door?

When we speak of reinforced doors, we often take for granted the so-called burglar resistance, while there is a European standard (EN1627) in force that governs and classifies the levels of security of closing systems in general.

As regards reinforced doors in the Italian market, the reference classes are: Class 2, Class 3 and Class 4.

The resistance class depends on the number of bolts (or pins fixed to the leaf that, when the door is closed, get inserted into the corresponding holes on the frame), the number of locking points (i.e. those operated by the lock through key turns and bolts), the type of lock.

2. What are the features of a Class 2 reinforced door?

Class 2 reinforced doors provide a moderate protection, preventing the intrusion of people trying to enter by means of physical force or with the use of simple tools, such as screwdrivers, wedges, pliers etc.
These doors are normally the most suitable for condominiums.

3. What are the features of a Class 3 reinforced door?

Class 3 reinforced doors offer better security than ‘Class 2’ doors, preventing the intrusion of a burglar who also makes use of large screwdrivers and a crowbar.
Generally, these are the right choice for villas, detached houses and offices.

4. What are the features of a Class 4 reinforced door?

Class 4 reinforced doors guarantee very high security, preventing the intrusion of an expert burglar who also uses tools such as saws, hammers, axes, chisels and portable battery drills.
Mostly are advisable in the case of isolated houses and mansions.

5. We hear about a 'Euro cylinder', but what is it exactly?

Compared to old double bitted keylocks, a Euro cylinder is safer and more sought after. Its features include three basic elements: the lock, the cylinder, the anti-drill defender to protect the cylinder.
Using an inadequate lock will negatively affect the security of the door.
So today it is essential to have a lock with a Euro cylinder.
