It's the camera. It's not as colourful in real lifeVery colourful what ever it is.
ThanksThe metal lath is in fact a roll of expanded steel mesh - aka ex-met . Rolled out and nailed to the joists.

@^woody^ what say you?It’d normally be done as a repair to wooden laths, I don’t think anyone would ever mesh the entire ceiling and plaster onto it
Yes, it's a real beast. Super solid and thick.It's a lot harder to take down.
It was quite common from around 1920's upto around 1950's but I've mostly seen it in non-residential buildings.
It was used quite a lot in the USA for ceilings before plasterboard. The galvanizing can break down over time leaving the laths open to rust and failure.
It's a lot quicker to skim plasterboard than fill EML or timber laths.
I think it was a post-war thing where there was a lot of steel and production capacity. Whole ceilings were done by this method, not just repairs.
