Angle steel L90x8/-140 – what does this “-140” mean?

As the title says.....
It has the same meaning as L140x90x8!
Original poster, you should write this topic more clearly – specify exactly what kind of document or drawing it is, and which data to refer to; otherwise anything can be said and it will confuse everyone···
If nothing goes wrong, this refers to the level of that support being 140 mm below the elevation of the platform on that floor. That’s how our institute expresses it. . .
