The idea

RC4 for architecture with distinction.

Developed on a proven RC3 basis and successfully upgraded to RC4.

PORTEC has systematically further developed a proven RC3 steel door design. Reinforcements, locking mechanisms, hinges, glazing, and panels now form a successfully tested overall system of resistance class RC4. This certified solution combines protection, escape route functionality, and architectural design – for entrances where security must not look like security.
