Gypsum board reinforced with plywood - how to fasten?

[Heggemony]

Living in an apartment with drywall as interior walls. A wall intended for TV mounting is reinforced with plywood behind it. If it were only drywall, I understand that I should use molly bolts for mounting a TV/wall furniture, for example in the rest of the apartment. But now that it is drywall+plywood, what should be used? I also see in pictures from the construction that there are regularly spaced studs made of steel if that adds anything.

I live in an apartment with drywall as interior walls. One wall intended for TV mounting is reinforced with plywood at the back. If it were just drywall, I've understood that I should use molly bolts for hanging the TV/wall furniture, for example in other parts of the apartment. But now that it's drywall+plywood, what do I use then? I also see from construction photos that there are evenly spaced steel studs if that adds anything.

If there is plywood behind, it should work fine to screw directly into it with an appropriately thick screw.

If there is plyfa behind, it should work fine to screw directly into it with an appropriately thick screw.

So you don't need molly plugs, plastic plugs, or anything? Just a plain screw? Even if it's for a TV or a wall-mounted TV bench underneath?

For example, a screw like in the picture?

Screw in and hang the TV on studs, then you won't have to worry.

In general, you should be able to handle that type of wall like a wooden wall, i.e., no plug.

But if you are concerned about the increased weight of a large TV, especially if you have a long arm or similar, you can always use mollyplugg intended for double gypsum that expands behind the plywood.
