Girder winched above new Canberra embassy in seconds (1-4)
I believe the answer is:
i-beam
'girder' is the definition.
(I-beam is an example)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for i-beam that I've seen before include "Rigid metal girder" , "Metal girder I-shaped in cross-section" , "Structural girder" , "Common type of metal girder" .)
