Steel security rated doors are designed to withstand physical attack for varying periods of time, with a variety of attack tools. The longer the attack time, and the more aggressive the tools used, the higher the doors’ performance rating.
Without certified test evidence of performance, any claims for a doors’ security are unproven.
Teckentrup 62 doors have been tested to all the widely recognised standards including the new LPS 1175 issue 8. The bracketed rating, e.g. (SR1) provides the equivalent under Issue 7 where applicable.
The commonly required security levels, along with the typical applications are shown below. The standard has more extended times and tool kits, however as, apart from highly specialised applications, LPS 1175 D10 (SR4) is generally the highest requirement and we’ve limited the listing up to this level.
