An armoured door weighs on average between 70 and 100 kg, although the weight can vary depending on the security class, the dimensions and the cladding panels.
In technical terms, an armoured door has a surface mass of around 35 kg per square metre, which means that a standard 90 × 210 cm door weighs around 66 kg without panels and around 80 kg with panels fitted.
Armoured doors of a higher class or with particularly heavy cladding can even reach 100 kg or more, while some made-to-measure doors with solid panels can exceed 200 kg or even 400 kg.
In this guide you will find out how much a standard armoured door weighs, how much an RC3 or RC4 armoured door weighs, how much it weighs per square metre and what really determines the weight of a security door.
How much does an armoured door weigh?
Many people search online for information about the weight of an armoured door or wonder how much a flat entrance armoured door weighs.
The answer actually depends above all on the dimensions of the door, the security class and the cladding panels fitted.
Here you will find a table with the average weight of a standard armoured door, in RC3 and RC4 security class, with a few reference figures on the weight per square metre.
| Type of armoured door | Indicative weight |
|---|---|
| Standard armoured door | around 80 kg |
| RC3 armoured door | around 80 kg |
| RC4 armoured door | around 100 kg |
| Armoured door weight per square metre | around 35 kg/m² |
| Armoured door without panels (90×210) | around 66 kg |
| Armoured door with standard panels | around 80 kg |
| Armoured doors with heavy panels | up to 200-400 kg |
As you can see from the table, the weight of a standard armoured door is around 80 kg, but it can increase significantly depending on the security class and the cladding panels.
How much an armoured door weighs per square metre
To really understand how much an armoured door weighs, the most useful figure to consider is the surface mass, that is the weight per square metre of the structure.
On average, an armoured door has a mass of around 35 kg/m².
This value makes it possible to estimate the weight of any door, regardless of its dimensions.
For example, let us take a standard flat armoured door with dimensions of 90 × 210 cm:
- door surface: 0.9 × 2.1 = 1.89 m²
- surface mass: 35 kg/m²
The weight of the door structure will therefore be:
35 × 1.89 = around 66 kg
This value refers to the door without cladding panels.
When the decorative panels (inside and outside) are added, the weight generally increases by 10-15 kg, bringing a standard door to around 80 kg in total.
The weight per square metre is the figure most used by manufacturers because it makes it easy to calculate the weight of doors of different sizes.
For example:
| Door dimensions | Surface | Structure weight (approx.) |
|---|---|---|
| 80 × 210 cm | 1.68 m² | around 59 kg |
| 90 × 210 cm | 1.89 m² | around 66 kg |
| 100 × 210 cm | 2.10 m² | around 73 kg |
To this value you then need to add the weight of the panels, the lock and the fittings.
Many people think an armoured door weighs hundreds of kilos, but the metal structure on its own generally weighs less than you might imagine.
The total weight increases above all when the following are fitted:
- very thick or decorative panels
- solid iron pull handles
- additional security fittings
In these cases the final weight of the door can grow significantly.
How much a standard armoured door weighs
When we talk about a standard armoured door, we generally mean a flat door with dimensions of 90 × 210 cm, which is the most common size in homes.
In this case the weight depends mainly on the internal metal structure and the cladding panels.
As a rough guide:
- armoured door without panels: around 66 kg
- armoured door with standard panels: around 80 kg
The figure of around 80 kg is therefore what we can consider the average weight of a home armoured door.
This weight makes it possible to ensure the structure is good and solid without making the door difficult to open or use day to day.
How much an RC3 armoured door weighs
An RC3 armoured door weighs roughly 80 kg, considering a standard-sized door of 90 × 210 cm with cladding panels.
This weight comes from the internal steel structure, the multipoint lock and the reinforcements needed to pass the burglar-resistance tests required for this security class.
It is the most common class in private homes, because it offers a good level of protection while keeping the door relatively easy to use every day.
How much an RC4 armoured door weighs
An RC4 armoured door weighs on average around 100 kg in standard flat dimensions.
The greater weight compared with RC3 is due to a more robust internal structure, with thicker steel sheets and additional reinforcements designed to increase resistance to break-in attempts.
Here too the weight can vary slightly depending on the cladding panels and the fittings installed on the door.
How much the components of an armoured door weigh
An armoured door is made up of many different elements, and each of these contributes to the overall weight of the door. Some components weigh just a few grams, while others can have a significant impact on the final weight.
Among the most important elements are the metal structure, the lock, the cladding panels and the security fittings.
The internal steel structure is the heaviest part of the door. It is made up of steel sheets and metal reinforcements that ensure rigidity and resistance to break-in attempts.
The multipoint lock also has a significant weight, because it contains several locking mechanisms that drive the deadbolts along the perimeter of the door.
Another element that can have a major impact on the overall weight is the cladding panels, especially when they are made from particularly thick or decorative materials.
In some particular configurations, the panels can become very heavy. For example, panels with a recessed defender or with significant structural work can even exceed 100 kg in weight.
Some fittings can also have a significant impact. For example, pull handles made of solid iron can weigh over 30 kg, especially when they are designed as large decorative elements.
This means that, with very solid panels or particularly heavy fittings, the total weight of the armoured door can increase considerably compared with the average figures.
Frequently asked questions about the weight of armoured doors
On average, a flat armoured door weighs around 80 kg in the standard dimensions of 90 × 210 cm with cladding panels. The weight can increase or decrease depending on the security class, the materials used and the fittings installed.
An entrance armoured door weighs on average between 70 and 100 kg in standard dimensions. The weight can increase in the case of large doors or those with particularly heavy decorative panels.
The average weight of an armoured door is around 35 kg per square metre. This value refers to the door structure without cladding panels and makes it possible to estimate the weight of the door based on its dimensions.
An RC3 armoured door weighs roughly 80 kg in standard flat dimensions. The weight depends on the steel structure, the security lock and the cladding panels installed on the door.
An RC4 armoured door weighs on average around 100 kg in standard dimensions. The greater weight compared with RC3 is due to the presence of more robust structural reinforcements designed to offer a higher level of security.
Many people think an armoured door is too heavy for a normal home. In reality this is not the case. Even though an armoured door can weigh 80-100 kg or more, the hinges and the frame are designed to bear the load without any problem. This allows the door to open and close smoothly even after many years of use.
An armoured door without cladding panels weighs roughly 60-70 kg, considering a standard door of 90 × 210 cm.
This weight refers to the metal structure of the door alone, made up of steel sheets, internal reinforcements and the security lock.
When the inside and outside decorative panels are installed, the weight generally increases by 10-15 kg, bringing the total weight of the armoured door to around 80 kg in the most common configurations.
An internal door weighs between 15 and 25 kg, while an armoured one weighs 70-100 kg.
An armoured door with heavy panels can reach up to 200-400 kg.
Conclusions
If you were wondering how much a home armoured door weighs, you now know that in most cases the average weight is around 80 kg, although it can vary depending on the structure and the panels installed.
RC3 armoured doors, among the most common in homes, generally have a similar weight, while RC4 doors can reach around 100 kg thanks to their more robust structural reinforcements.
It is worth remembering that the weight of an armoured door is not a drawback in everyday use. Hinges, frame and fixing systems are designed precisely to bear high loads and ensure smooth opening, stability and long-lasting performance.
In some particular cases, such as large doors or those with very solid panels, the overall weight can increase significantly. However, in the most common installations the reference figure remains around 80 kg for a standard armoured door.
