Hi all. Working on fawley jetty at the moment and have noticed that most of the alloy beams being used suffer from oxidation from the salt water. Would this affect the integrity of the beam and eventuality lead to failure? Would galvanised surebeams be a better option?

a splash did you hear a splash.... i didnt hear no splash. lol

youll have to ask old alan on this 1 at a guess it will effect it if under for long periods of time due to the fact alloy will corrode fast as its more active than steel but still steel will corrode obvusly under water that is 1 reason you shouldnt mix alloy with steel the alloy will be come weaker faster, if you notice on a dropped fordge doubble the bolt rusts fast than the body this mean the bolt it a more active metal and the dropforge is a noble metal
 
Salt water won't corrode aluminium.

it will ozidise in salt water but wont corrode like steel . alloy will get a layer of what lookes like corrosion but its like a protective layer, wear as steel will contsantly corrode ad it flask rust off
