Tie rusts badly (5)

I believe the answer is:

truss

'tie' is the definition.
(I know that truss is a type of tie)

'rusts badly' is the wordplay.
'badly' indicates anagramming the letters.
'rusts' anagrammed gives 'TRUSS'.

(Other definitions for truss that I've seen before include "Bind like a chicken" , "Bind - structural framework" , "Support - bundle - cluster" , "Bundle of hay or straw" , "Corbel, in architecture" .)

I've seen this clue in The Irish Independent.
