RE: Drawings of Old Steel Bridges

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Just a guess.  If it's a shop drawing from a fabricator, it could mean
"Piece Mark No. 3, Right-hand", especially if there is one marked "3L".

	Hello everyone,

	I have a set of drwaings and details of an old steel bridge. Next to
	designation of a channel used for bracing, there is a notation "3R".
Can
	someone explain to me what it means. For example: 13C13.8# 3R

	Many thanks in advance,
