MCA #1 Treated Pine

Treated Yellow Pine is a commonly used option for decking.  Most often, price is the main reason for picking treated pine.  From an appearance point of view it is far from the best choice.  Yellow pine is an unstable wood by nature.  When pine gets wet and swells then dries and shrinks back, it develops large splits and tends to move dramatically, both warping and twisting. It is not naturally resistant to decay and insects, so it is treated with chemicals to give it those properties.

As a framing material it is the best choice.  Where it is not exposed to the sun, it does not have such a tendency to split or move.  The chemicals added to the wood make it very rot resistant.  However, due to the climate we live in here in Texas, on a deck surface you are likely to begin replacing boards within a few years due to splitting and cupping that will occur.  If it is kept stained or sealed, this will reduce these problems to some extent.
