It's been a long time since we talked about security doors, so we believed it was due time for a refresher. Let's start by advising ourselves what they are and why we need them.
What is a security door, and why do we require them?
Put simply, and as the name suggests, a security door provides boosted security and protecting from different unwanted situations and circumstances; as an effect they are most likely to be heavy duty and of extremely strong (often but not always metal) building, and excellent care will have been handled their style. There are a number of reasons we might need them, chief amongst which are:
avoiding undesirable access (mindful as constantly of emergency evacuations).
avoiding or slowing down the passage of fire and/or smoke.
security-- a design that removes the possibility of fingers getting trapped in the door.
Ramifications of not installing security doors ...
Well, there are several, and they all hinge (no pun meant) on being not able to prevent the undesirable things taking place: if your doors are not protect then it's simpler for individuals to break in and steal or harm your goods and residential or commercial property; fire and smoke will spread far more rapidly; and people's fingers can get trapped in closing doors. So we're discussing various points on the scale which vary from real death through breaking the law and contravening guidelines through badly damaged hands and fingers through loss/damage of/to important assets to raised insurance coverage premiums ... with all sorts of business ramifications.

PAS 24.
This is your assurance that the door is being kept an eye on by a UKAS accredited accreditation body to ensure compliance with PAS 24:201.
Improved security performance requirements for doorsets and windows in the UK. External doorsets and windows intended to provide a level of security suitable for residences and other buildings exposed to similar threat and the specific and the appropriate material particular standard for basic efficiency referenced in BS 6375 Parts 1, 2 and 3.
PAS 24, like many British Standards, is a minimum requirement. To put it simply it doesn't consist of greater or lower grades for security, therefore doors that are checked to the specs of the basic either pass or stop working. Although some of the doorsets that pass will be a little more powerful than the minimum needed, a minimum standard motivates engineers to design the door to pass at the minimum requirements. This makes financial and environmental sense and the efficiency of doors certificated to this standard has actually shown that the minimum levels set by the British Standards were practically spot on.
Classes of usage.
Since there are all sorts of various environments where security doors are needed, many of which are used by the general public, as you may expect there is a British Standard to help guide you through what type of door you require: DD171:1987.
The basic sets out four levels or classes of use:.
Light responsibility-- low frequency of use and probably not that severe, such as in a personal house.
Medium duty-- medium frequency of usage, some possibility of a mishap, however the door is not normally utilized by the public-- for instance an internal office door.
Strong-- lots of use, including by the public, and a reasonably high possibility of an accident-- for example in a retail outlet.
Serious task-- the only image you need to have in your mind here is a school when the bell opts for playtime and all the kids run towards the door. Enough said!
