Is a roller shutter possible for a large lift/slide door?

A rail is installed where the roller shutters are guided. For 6m, they are almost certainly aluminum roller shutters; plastic no longer works there.

"Is" still nothing at all, that was just in the first draft and I was just wondering how it would work with the roller shutter. Because a real roller shutter is mandatory for us, blinds are absolutely not an option...

Thanks for the note about the rails. Are there possibly pictures of how it looks with the rails? Despite some googling, I haven't found anything yet.

Here with rail

But our door is only about 4 meters wide, but the rail is visible.

That is good - the chance to reconsider it should be taken. Below 15 m width on this side of the house, it also looks crooked.

At 6m it is very definitely aluminum roller shutters, plastic is no longer possible.

The sliding lift door itself should also urgently be recommended to be made of aluminum - even if it is supposed to be white. Unless you are married to a weightlifter, it is advisable to try moving such a beast live in the manufacturer's showroom.

But our door is only about 4 meters wide but the rail is visible.

I see two doors about one meter wide each...
And I don't understand why the roller shutters are separated there.

Huh? On the left is a sliding door with a width of 4 meters and no doors. One element is fixed and the door slides in front of it.
