What is the difference between green treated and pressure-treated wood?
Green timber has a naturally-pale, wooden colour but you will also note a slight green tint or fleck caused by the pressure-treating process.

How long do chemicals stay in pressure treated wood?
More than 90 percent of all outdoor wooden structures in the United States are made with arsenic-treated lumber.

How long will a treated 4×4 post last in the ground?
A treated 4×4 will last 20 to 25 years in the ground if the conditions in the soil and climate are favorable. That number could increase to 40 to 75 years if you install the treated 4×4 in a cement ring rather than the soil. There are a few factors that influence how long the 4×4 can last in the ground.
