hi there,
this is from the last property owner renovation. it seems they put a new plasterboard on the wall. but there is a gap between door trim and plasterboard. and I can see there is a metal piece between the board and trim.
anyone know what it is?

Looks like plaster trim.
Why do you want to know?
