Are Steel Doors Harder to Break in than Other Doors?
A steel doorset, with a steel sub frame and high quality, integrated hardware and locking will be one of the hardest types of doors to break through using just force and medium ranked hand tools.
Most steel doorsets wil use a double skinned steel sandwich leaf and this will be between 40 - 60mm thick and have a core filling, which varies depending on specification required.
As many standard, higher quality steel doors have an integral astragal seal on the outer face, this means you have no gaps showing outside, so no place to even start levering into with attempted force.
Look towards the locking and again, assuming the build quality is higher end, the cylinder will be anti tamper and almost impossible to force without some very high end power tools and attachments.
Many so called 'security' steel doors throw claims around about 6 or 9 or 12 point locking points, but this is all academic if the actual lock they attach to is of a low grade and quality. Break the lock and you can operate all the points of locking if the door has all the multi point locking going through the one lock cylinder.
Yes, a proper steel doorset will be a very hard door to force and break through, even at low levels of tested and certified security rating.
We have witnessed so called 'security' steel doors broken into within 20 seconds using only a large screwdriver... Controlled tests, not real life break ins, just to be clear..
Buy cheap, buy twice, but also lose stock, equipment or belongings at the same time!!
