No, I don't think that is what is causing it. That video just shows someone playing as a dummy and a random glitch.

Have you tried raising the material to something even stronger like test material?

Same effect with Test, Mega Metal and Door Metal.

Depth/resolutions

Copy them from the vanilla doors

Still breaks ._.

Oh.

Stop using MOSRotatings. Constant collision doesn't work in current engine.

Use immobile doors instead.

Or I don't know what the problem is, the thread is unreadable.

Have a look at this mod.

I haven't personally looked at the code myself, but it accomplishes what you are trying to achieve, a bunker module that can gib. Maybe it can help you.

EDIT: I just looked at it. It appears to work by using a MOSRotating as the base and using attachables for the different parts. Maybe you could try something similar, and build it out of attachables?

Still wouldn't be collideable.
