Ngl those are some beautiful beams

Partially correct. Those are beams, girders, and columns.

A girder (/ˈɡɜːrdər/) is a beam used in construction.

Specifically a girder is a beam that other beams frame into. Gravity load typically goes slab->beam->girder->columns->foundation. At least that's what I teach in my steel design classes.

Are there any girders in the picture then? Or none, or impossible to tell? I can't see any, by that definition.

You can see them on the upper levels. On the bottom level, you can see the shear tabs, mounted on the girders that additional beams will frame into.

c/lemmyshitpost, come for the memes, stay for the lessons on construction materials

Little known fact; heavy timber buildings will often perform better in fire than steel buildings like this.
