Why use the LPS 1175 Issue 7 SR4 Steel Security Doors?

The LPS 1175 Issue 7 SR4 security door is a steel door that is independently attack tested by BRE. This falls in the high level of security rated steel doors available.

The dorset is attacked with a variety of hand tools fora maximum of 30 minutes, with a maximum working time of 10 minutes. If entry through the door is not gained then the dorset receives the LPS 1175 Issue 7 SR4 level rating.

To meet the required certification the door has to be provided within the scope that has been tested. If the specification you require falls out of the scope, we can still provide a door to the same spec but it will not be certified.


All LPS 1175 Issue 7 SR4 security doors are bespoke and take around 18 - 24 working days to manufacture.

Large range of options and colours available.
