Everything you need to know before buying a security door

These are the points to keep in mind when buying an armoured security door – πόρτες ασφαλείας.

Robbers are constantly finding new ways to break in and have found many ways to handle security doors that do not fulfil security characteristics.


Very important when buying a product, especially when it comes to the security of our property and many times in our own lives, is the choice of this product to be made by a well-known company, years in the field which to inspire confidence.

Unfortunately products that do not meet safety standards are of doubtful quality and origin on the domestic market.

There are many Greek companies that manufacture armoured security doors – θωρακισμένες πόρτες ασφαλείας – offering high levels of security and quality many times higher than other European sites.

Security Certifications

An armoured security door – portes asfaleias – should have a burglary certification (the most important certification) knowing the consumer the security that it can provide. The burglary certification is classified in Classes 1-6.

The greater the degree, the more secure it is, thus showing us the anti-burglary protection it provides by international standards. Additional certifications are those of sound insulation and thermal insulation.

Warranty of security door

Many companies in the field provide some guarantee of good product operation. This can range from 1 to 10 years. It is very important to be aware of exactly what this warranty includes so as not to be surprised when it creates a problem of either operation or security.

Service – Benefits

When choosing, we should be informed about the service provided by the company from which we will choose the security door. If it for any reason suddenly does not lock or close it should be repaired as soon as possible.

Shield type of security door

Important when choosing a security door is the shield type. There are two types of shielding: single shielding and double shielding. Single shielding usually consists of a one-piece boat (outer side of the door) and 1 to 3 nerves (inner side of the door).

The double shield also features a one-piece boats (outer side of the door) with 3 or more ribs internally, thermal insulation (necessary for energy-efficient spaces), sound insulation and finally a door inside a one-piece metal sheet. Therefore, the higher the shielding the more robust the door providing greater security.

Steel sheet type and quality of security door

The main part of a security door is made of steel sheet. Quality and thickness are important. The best quality sheet metal for making a shielded security door is the non-rusting electro-galvanized sheet (this type of sheet metal is used in the automotive industry). Types such as black or decapitated rust causing the door to cause problems after a while.

The thickness of the sheet is from 0.5 to 1.5mm. The most common and which meets all safety and durability standards is 1mm. Lower thickness poses significant durability and safety problems in a burglary attempt.

Metal frame

The metal frame is the one that supports the security door. Important factors are the thickness, shape and colour of the frame. The correct thickness of a sheet metal is 2mm, less thickness e.g. 1.25mm does not provide the required support and durability.

The profile of the frame must be configured to provide maximum resistance to an attempt to break the door. Finally, the metal frame should be painted with an electrostatic paint that will withstand the weather and weather conditions.

Lock Type

The type of lock on a security door has the most important role for our security. Modern locks are roller locks. There are too many types and some points need to be taken into account to provide extra security (e.g defender, catapult, etc.).

Along with the lock – κλειδαριές ασφαλείας – is the safety roller and the defender (roller protection). As with locks, there are many types of locks. Security rolls that can only be copied with the ownership card provide greater security.

Investing in a security door mainly satisfies the aesthetic part and sometimes protect the door from extreme weather conditions such as rain, humidity, etc. (aluminium cladding).

What are the types of investments?

  • MDF glaze coating with natural veneer
  • Laminate linings
  • Aluminium linings

There are pantograph designs, handmade, stainless steel surfaces, etc. See the designs here. Solid wood investments are rare due to high costs. What to look for is choosing the right investment for the space where you will install the security door.

For example on a door that is exposed to rain, humidity, etc. no glazing or laminate coating but aluminium should be chosen.


The last point to pay attention when buying a security door is the placement of the door in our area. Many companies have their own workshops with the propriet qualifications for the optimal placement of their product.

It is very important for a security door to be positioned properly, avoiding any future operating or security problems.
