Corroding joist hangers

Do you ever call out corroding joist hangers and rusting nails on connectors on decks?

We had a Simpson rep at a few association meetings ago who reccomended nothing less then their Z-max connectors as the standard hangers and fasteners just can't stand up to the new PT wood. I would say thats probably a fact.

Absolutely! It's a serious life-safety issue that needs to be reported.

Corrosion on the connectors or fasteners is an indication that they were not properly matched to each other, to the preservative in the wood, to the environment in which they are used, or a combination of all of these things. This became more of an issue once we moved away from CCA based wood preservatives during the early 2000s.

Simpson puts out some good info on this, available here:
