HARTMANN bullet-proof doors –
The ideal protection for larger spaces

Bullet-proof doors – or ‘strongroom’ doors to give them their official title – are an excellent alternative for companies, authorities or private individuals looking to protect both high-value and large quantities of valuables from unauthorised access. Particularly in the case of new builds or renovations, strongroom doors can be incorporated directly into the building if there is not enough room for more conventional options, such as burglar-proof and fireproof safes, filing cabinets and wall safes.

No matter whether you are interested in storing important files and documents, extensive collections, weapons and ammunition, or narcotics – wherever space is too tight for a standard safe, strongrooms with the appropriately tested bullet-proof doors offer a secure and convenient solution.

Vaults – security for an entire room

Also known as a compound or modular vault, a strongroom is made up of individual wall panels that are assembled and welded together on site. These strongrooms contain a multitude of customer locker systems that can be hired out – for example, in banks and building societies. Strongrooms are used not only within the commercial sector, but also by refineries, jewellery makers, gold purchasers and asset handling companies. A modular strongroom is also an ideal option for pharmaceutical companies when it comes to applications such as storing narcotics and expensive special diagnostics devices.

In its most basic configuration, a strongroom is essentially a room with a strongroom door. The ability to secure an entire room provides protection for larger quantities of valuables. Their composition and exact material characteristics are not communicated externally. On account of its heavy weight alone, a strongroom door must be installed by a professional.

Walk-in gun safes – legally compliant weapon storage

A walk-in gun safe can be an attractive option for those with large weapon collections. The important thing to note is that the armoury must comply with statutory requirements. Ask your responsible regulatory authority or the police if you require further details in this regard. You can also take a look at our Weapons Act page for more information.

Key factors to consider when thinking about a strongroom are not only the bullet-proof door, but also the masonry of the room itself. The thickness of the walls is just as important as the material being used: aerated concrete and hollow blocks are now largely considered inadequate, whereas solid bricks and reinforced concrete are perfectly acceptable from a security perspective.

Buying a bullet-proof door

HARTMANN TRESORE is synonymous with security. Over 200,000 customers have already made the decision to invest in one of our security solutions. At HARTMANN TRESORE, you can buy the perfect bullet-proof door to meet all of your security needs.

If you’re looking for a bullet-proof door to protect a strongroom, it’s easier to incorporate one if you have thought about it right from the initial planning stages of the building. Don’t underestimate the requirements with regard to the structural design of the house and transportation of the unit – after all, the strongroom door alone can weigh more than 850 kilos.

Protecting archives

The requirements surrounding the protection of files within an archive can vary. If you are working with personal data and storing this information in paper form as well as digital, the subject of data protection has a huge role to play. Similarly, file retention requirements – applicable in the case of lawyers or doctors, for example – may make it necessary to create a strongroom complete with a bullet-proof door to ensure this data is secure. In some cases, the retention periods to be observed by lawyers and notaries can extend to 10 years (information correct as of 02/2017). Many of the documents in these industries are required in writing, and it is not always possible for reference files to be stored digitally, which is why there is an increased need for protection here in order to remain covered during the periods of limitation for a client’s compensation claims.
