Certified burglary resistance according to DIN EN 1627, optimized airflow, and modular design – with “TrafoLG”, Hodapp GmbH & Co. KG expands its security portfolio for sensitive technical facilities.
In an increasingly complex risk landscape, where critical infrastructure must be protected against targeted attacks, sabotage, and extreme weather conditions, robust physical security solutions are gaining strategic importance. Hodapp GmbH & Co. KG responds to these demands with the development of the RC5 security grille “TrafoLG” – an innovative solution that combines certified intrusion resistance with technical functionality.
With resistance class RC5 in accordance with DIN EN 1627, “TrafoLG” meets the highest current standards for mechanical security in grille systems. The grille is specifically designed for use in high-security zones – such as transformer stations, data centers, military facilities, or government institutions with security areas complying with BSI standards. It reliably protects against forced entry using powerful tools while maintaining functionality: an effective ventilation cross-section of 36% ensures the necessary air circulation in heat-sensitive areas.
Uncompromising Security – Thoughtful Design for Demanding Applications
The requirements for protecting technical installations today go far beyond simple barrier functions. With “TrafoLG”, Hodapp offers a security grille that impresses with mechanical robustness as well as architectural flexibility. The system’s surface finish and construction can be customized for each project – both visually and technically. This enables operators to ensure not only reliable protection but also seamless integration into existing facility designs.
A key feature is the modular construction, which allows for precise installation across a wide variety of building types – from new constructions to retrofit applications. In combination with optional components such as pressure relief slats, weather protection elements, airflow regulation, or special high-performance coatings, “TrafoLG” is ready for environments with specific climatic or technical security requirements.
Tested Quality – Engineered for Maximum Operational and Supply Security
All security-relevant components of the RC5 grille are tested according to strict standards. The RC5 classification is based on simulated attack scenarios using heavy-duty tools such as angle grinders or drills. The grille construction withstands these impacts for at least 15 minutes – a critical time buffer for monitoring systems, response teams, and emergency shutdowns.
Especially in critical infrastructure like power supply facilities, data centers, or military areas, this resistance time can make the difference between damage and protection. The system’s high airflow capacity also makes it ideal for transformer rooms or server environments where continuous ventilation is essential to prevent overheating or system failures.
Practical Implementation Through Experience and Specialization
Hodapp brings over 75 years of experience in the development and production of specialized doors and gates to this new product. The company headquarters in Achern, Baden-Württemberg, focuses on technically complex, project-specific solutions – whether in steel, stainless steel, or increasingly also in aluminum. The development of “TrafoLG” reflects the company’s commitment to not only meeting regulatory standards but to advancing security products through engineering intelligence and practical application.
Manufacturing is handled entirely in-house – from design and certification to quality assurance. This ensures a reliable supply chain, clear lines of communication, and consistent adherence to high standards throughout all phases of a project.
Conclusion: “TrafoLG” as a Building Block of Holistic Security Concepts
With the RC5 security grille “TrafoLG”, Hodapp offers a robust, flexibly deployable solution for operators of critical infrastructure who require both certified security and technical performance. Whether for new construction or retrofitting, the system is designed for customized configuration and sustainable operation. Optional enhancements such as high-performance coatings or weather protection modules further extend its range of applications.
“TrafoLG” exemplifies Hodapp’s commitment to delivering security technology that combines substance, durability, and system intelligence – for operators who demand not only protection, but protection with strategic added value.
