Door gate/screen thing help

[IzzyHandsIsMySpiritAnimal]

Thought I'd posted this yesterday but looks like something went wrong.
Wondering if anyone can help me track down a product.

My MIL lives opposite some people who have this rather fancy wrought iron looking screen door (a bit like a garden gate but more sturdy) which they can lock across their front door, and then open the door itself to allow airflow.
I can't seem to describe it very well and wanted to try to look up where they might sell.
However, MIL doesn't know the people across the road and I don't really want to knock on a stranger's door to ask.
I can't work out what to call this screen/door/gate in order to search online.

Any ideas? If I put 'metal screen door' I just seem to get mesh fly screens. If put 'metal door gate' I get either garden gates or solid metal shutters.

They were called Rape Gates when we lived in Papua New Guinea, although that was probably only on bedroom doors.

Try goggling "security gate for front door", seems to give what you want.

I googled "front door security gate" (similar to the post above) and got loads of results for companies that do this.

Most of them are fairly plain, but there are some fancy wrought iron ones too.
