Barricade a door with box section

[OldKettle]

Hi,
I have an external side door which is never used, and will likely eventually be bricked up, but I want to secure it for now, with some kind of drop in barricade.

The door is in a corner with brick walls at both sides (the hinges are in the corner).

I had planned to barricade it with timber, but because it is in a corner any bracket that side would have to be flush with the wall.

Plan B is to use box section, with holes drilled into the wall at the corner, and then brackets, on the other side.

I was hoping that I could use 25mm x 25mm x 3mm mild steel.

Will this work? Is there a better way?

Not a bad idea but I'd be inclined to go up on your material section, perhaps to 50x50x6 angle?

I'd use 30x30 box section however, make sure that you have it far enough into the wall that it cannot be bent and pulled out.
make sure the brackets are really strong and that any padlocks you use on them are not your weakest link.

Many many padlocks can be opened with a slither of coke can, its on youtube - the crims know this - get some that cannot of make it so the bracket covers the lock and only gives access to the bottom.

Just screw thru door to frame.

that was exactly what the retail unit next door did after burglars had smashed through the shop door.

Thanks for this, and to everybody else who has commented. I should have been clearer that the barricade will be on the inside of the door.

As such I hadn't planned to use any padlocks, just brackets on the handle side (the hinge side been in the wall).

Any suggestions on brackets and/or depth of holes would be much appreciated.

just brackets on the handle side

A pin in the brackets to prevent the bars being lifted out if the intruders make a small hole and can then get an arm through it to remove the bars.

The holes can be reinforced by a vertical steel strip screwed to the frame. A single strip from top to bottom of the frame and with screws above and below each hole in the door frame

The bars should be as close to the door as possible, touching if possible to prevent the door bowing and cracking when attacked

Add extra layers to the outside of the door, steel sheet would be good.
This worked quite well for my back door a few houses back.
use right angle on the frame.

A sheet of 18mm ply covering the door and frame, then screwed into the frame at every 150mm.
