I would just like to say

Below is a pic of the top of me garage doors where they meet int middle. Each door has a bolt that goes into the floor. I want to put something at the top to secure the doors anorl. Problem is ma hippo is 1.86m tall. The gap below the metal beam is 1.9m so there's only a gap of 40mm clearance.

The obvious thing would be to drill a hole through the metal beam but I think that's a risk as it will weaken it. The metal beam has a triangle of bricks above it which it supports.

Something that attaches to the door and feeds under the metal beam and up to the bricks above, and secured to the bricks may be possible. Any other ideas?

I cannot see drilling a hole in a steel lintel will weaken it any. It is not like you are going to drill a whole series of them across it. A couple of 10mm holes, one for each door will suffice.

Drilling a couple of holes through the flange of the I-beam will not affect its strength. The stiffness of the beam is nearly all in the web. The top and bottom flanges are there to resist torsion, and bending in the horizontal plane, there are no forces trying to move the beam horizontally. (I studied structural engineering at collij and I is a re-tyred civil enjineer). And I own a fender so you can trust me :p:D:p
