Hello.
Do you think corrosion is happening on these galvanized connector plates?
The truss system is one year old.
The connector plates have a low level corrosion resistant coating (G90)
Thanks.
These plates were sprayed by corrosive chemical solution(similar to bleach) so they became like these.
Almost all truss connector plates of this one-year old house look like these pictures.
Is a repair required immediately to extend the longevity of the structure?
How to repair? With WD40?
Thanks.
The lifetime of these connector plates might be shorter than brand new ones.
So I'm wondering if there's a way to prevent them from getting worse.
Any method?
If it were mine I probably wouldn't be too concerned about it.
That said, you could clean them and paint them. Paint over galvanizing is one of the more robust options out there for protecting steel from corrosion.
