Have a look at this picture: enter image description here

It's from Airliners.net (though I've modified it a lot) and shows some lines on the fuselage. What are they? Are they Lightning Diverter Strips like in this question ?

No, they are just the boundaries between skin panels. See below for a picture of the 747-8 fuselage during assembly.

And this is how the panels for the cylindrical section look like before they are joined:

These lines are skin laps. The vertical ones do not overlap, the horizontal laps overlap by three rows of fasteners.

  • The downvote wasn't mine but it would probably help if you explained what a "skin lap" is. The asker surely wanted to understand what they are, not just what their name is. – David Richerby Aug 23 '16 at 10:22
