National Barn Company s standard posts have a .40 CCA treatment. The manufacturer has a limited warranty for 40 years, but the life span of the post should far exceed 40 years. A .60 CCA treatment is available for additional cost and has a 60-year limited warranty from the manufacturer. Post Protectors are also available to offer additional protection from moisture and termites; they have a lifetime limited warranty. A concrete pier system can also be used and the posts do not touch the ground.
