My local lumber yard did say the good stuff with the arsenic has be outlawed. He also mentioned that they upped the copper content to make up for the loss of the arsenic. The copper when it gets wet, now reacts with the zinc in the hangers and causes corrosion which affects the iron in the hanger and eventually hanger failure. The wood probably has a lesser life span because it has less bug killer built in. He further stated that the new hangers have an extra heavy coating of zinc, so the iron inside will be further protected, and should last longer. He also suggested using stainless screws to hold the deck planks. Boy an I glad I built my deck two years ago. I don't know how many pounds of epoxy coated screws I went through, but I would have needed a second mortgage if they were stainless. This years project is a storage shed. This thread has given me lots of good idea's. I'll be going with the concrete footings.
