randynavarro Posted February 12, 2007 Report Share Posted February 12, 2007 New deck. Less than 1 year. Simpson brand "Z" hangers are used to hang the joists - hardware specifically for use with the new generation of treated wood. Joists are pressure treated. There is corrosion on every single hanger. . . ? Any thoughts? Quote Link to comment Share on other sites More sharing options...

chicago Posted February 14, 2007 Report Share Posted February 14, 2007 The wood looks moist.Any chance its some sort of mineral deposit coming from chemicals in the wood. Quote Link to comment Share on other sites More sharing options...
Brian G Posted February 14, 2007 Report Share Posted February 14, 2007 It looks fairly uniform. My first thoughts are a salty or alkaline environment, or a simple manufacturing defect. I'm not even sure if this type would react to the salty or alkaline though... Is this near the coast? Brian G. Big Fan of Salty [] Quote Link to comment Share on other sites More sharing options...
randynavarro Posted February 14, 2007 Author Report Share Posted February 14, 2007 Is Seattle the coast? I guess, indirectly. But no, its not direct exposure to salt water. I guess we probably won't hit a definitve answer unless we were to call in the chemists!! My best theory at this point, is that the decking has been coated with some sort of oil or sealer that is attacking the metal. The wood is some sort of Brazilian hardwood - ipe or jatoba or some cool-sounding-wood-that-sounds-good-to-put-on-the-real-estate-flyer-and-get-a-lot-more-money-for-the-home sort of wood. Perhaps the coating wasn't the run-of-the-mill linseed oil or such. First time I've seen it, though. I thought the "Z" series was supposed to be pretty inpenetrable stuff.
