Effective protection against break-ins is becoming increasingly important – whether for commercial properties, public buildings, or high-end private residences. All of them require well-designed security solutions that not only act as a deterrent but also provide reliable protection in the event of an incident.
The Lindner Group offers tailor-made systems that combine certified security with architectural design freedom and can be seamlessly integrated into a wide range of building types. Our systems significantly increase the technical effort required to gain unauthorised access, thereby greatly reducing the likelihood of a successful break-in.
Our burglar-resistant systems are tested in accordance with DIN EN 1627 and meet resistance classes WK/RC1 to WK/RC6. This classification covers all realistic attack scenarios: from simple prying tools to professionally used power tools. Consistent quality assurance – from planning and implementation through to retrofitting – ensures that our solutions continue to operate reliably in the long term.
Burglar-resistant doors form the first physical barrier against unauthorised entry and play a decisive role in determining whether an attempted break-in fails. The Lindner Group offers doors in various resistance classes (e.g. RC2 to RC4), which can be individually tailored to the specific level of risk. They can be equipped with mechanical or electronic locking systems and further combined with access control, panic functions or escape route technology – providing a multifunctional solution that ensures both security and convenience.
Our burglary protection solutions go far beyond doors: windows, façade and wall elements are fully integrated into the overall security concept. In addition, our systems can be combined with supplementary functions such as fire protection, sound insulation or bullet resistance. The result is integrated security solutions that provide comprehensive and long-lasting protection for people, assets and buildings – without limiting architectural design freedom.
The burglar who manages to get through our doors has yet to be found.
Our burglar-resistant doors withstand even the most forceful attacks – their protection remains intact even under extreme physical assault. Tests conducted in accordance with DIN EN 1627 demonstrate this clearly: creating a hole like the one shown in the picture simply isn’t possible with our doors.
Thanks to their robust construction, reinforced fittings and innovative locking systems, they form an impenetrable barrier. At the same time, they can be flexibly adapted to the required resistance class (RC2 to RC4) and provide reliable protection for both new builds and retrofit projects.
Optional features such as door viewers, bolt monitoring contacts or self-locking mechanisms complete the security concept – ensuring maximum protection and everyday peace of mind.
Burglar-resistant doors from the Lindner Group impress not only with their protective performance but also with their high-quality craftsmanship and versatile design options. Security doesn’t have to look heavy or intrusive – our solutions combine proven robustness with architectural elegance.
Key Quality Features:
Burglar-resistant systems from the Lindner Group are used in office and administrative buildings, judicial and government facilities, banks, research institutions, educational establishments, and exclusive residential properties.
The resistance classes RC1 to RC6, as defined by DIN EN 1627, represent typical attack scenarios – ranging from opportunistic intruders using simple tools to professional offenders equipped with heavy-duty instruments. Our systems are tested under realistic conditions, meet the highest standards, and take into account not only doors and windows but also adjoining components such as walls, joints and connections. The result is a comprehensive security concept that leaves no weak point unprotected.
