Security class RC3: what it means for flat entrance doors
When choosing an entrance door for your flat you will come across the term security class RC3. We explain what it means and which door parameters stand behind it.
What RC3 means
Security classes express how long and with what tools a door resists a break-in attempt. Our security doors are certified in security class 3, which is the recommended standard for flats. You receive a certificate with the door.
What makes the door resistant
- 10 locking points – 6 active bolts of the central lock and 4 fixed bolts against lifting out, which slide into the steel door frame,
- 8 anchors, with which we anchor the door directly into the wall,
- steel leaf with a shell of 1.25 mm thick steel and internal reinforcement of the same thickness,
- steel door frame made of 1.5 mm thick steel, set in concrete together with the threshold,
- security cylinder in security class 4, resistant to drilling.
Installation is part of security
Even the best door loses its resistance if it is badly fitted. That is why we anchor the door frame and pour concrete around all of it. We describe the procedure in the article Installing security doors.
Warranty
We give a 7-year warranty on the lock and 5 years on the door construction and surface, door frame, handle, cylinder and installation.
