Questions about rebar

[fernando]

Hi Captain,
If i understand what you mean ...
I see local anchors made with this type of steel ... although i guess this is saved from other applications, just to make it cheap for modest fishermen.
But where i see these being massively applied is for construction, in either concrete beams or solid pavement. They call it "pre-stressed" concrete. Frames are made with rebar (if i get it) and after, fresh cement fills up the the desired structure volume. It then works by contraction, gaining more resistance. I guess in some cases the bars are laid streched with hydraulic jacks, before cement is applied and when it dries, the bars are let loose, improving the beams strength.
I may talking nonsense; if so, forget the whole thing .

Can you post some pictures? Sometimes in the US we use rebar to make hoopnet and trotline drags to locate our fishing gear that's been hidden out of sight of others. They look like grappling hooks and often get lost to tree roots, rocks, etc. It would be easy to see how one that was lost to a river, recovered a time later, and cleaned could look really old.

Thanks, gents, for your fast replies! I realize that I probably should have posted my question under 'ethno items'...sorry! Let me post a pic and you'll see what I'm talking about.

This whole piece, although partially cast (?) and of rebar, appears to be blacksmith made, with hammer tooling, primitive construction. Note to top securing ring. This piece was reportedly found at the coast of North Carolina, (my state) the 'Graveyard of the Atlantic'.
