Lumber is not cheap and either is labor if you have to do a project more than once. 4×4 lumber is an essential building block of construction, most commonly used as posts in the framing of houses, sheds, and many other structures. Like most lumber, 4×4 lumber gets its name from its dimensions. Depending on the demands of your particular project, 4×4 lumber can be purchased both treated and untreated. Just keep in mind that a treated 4×4 is going to be significantly heavier. Why You Should Inspect 4×4 Lumber If you need 4x4s (or any other large posts, really) inspect them first. Why? Many of them, especially 8-ft. posts, come from logs used for veneer, which is peeled from the logs like paper towels from a roll, leaving only the very center of the log. The center “pith” is the least stable part of the log and is very prone to twisting, splitting and bowing. This is particularly true of treated 4x4s because the treatment exaggerates the warping. Look for posts without a “bulls-eye” and growth rings from edge to edge. Perfect lumber is rare. Find the best you can.
