Not all pressure treated split rail is "Treated Equal"

Our Appalachian Split Rail, with its Southern Yellow Pine post, gives you a longer lasting product than other pressure treated split rail on the market with a mixed hardwood post.

The American Wood Preservers' Association requires a .40 retention for material in contact with the ground. Mixed hardwood posts, Poplar in particular, will not normally treat to this retention. This results in the mixed hardwood posts failing after a few years of installation. The Southern Yellow Pine post, which will easily treat to the .40 retention level, will provide years of maintenance-free service.
