How much load can a 6x6 post take?
The load capacity of a 3-foot #2 grade 4×4 is 17,426 pounds, and a similar 6×6 is 20,834 pounds or 16% better. However, an 8-foot 4×4 supports 6468-pounds and 2339-pounds at 14-feet, while a 6×6 is 18032 and 10550-pounds respectively – or 64% and 78% more load capacity.
How long does a 6x6 pressure treated post last?
Whether for framing only or the decking too, pressure treated lumber lasts a long time. Pressure treated lumber exposed to freeze-thaw and wet-dry cycles without care or maintenance will last about 9-years. With proper maintenance and treatment, the same deck will last 40 plus years.
How deep should a 6x6 post be in the ground?
The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet). Add about 6 inches of QUIKRETE All-Purpose Gravel into the bottom of the hole.
Can a 6x6 be used as a beam?

Why are my 6x6 posts splitting?
While extreme loading can cause a wood beam to split and would indicate a sign of impending disastrous collapse, usually the splits or cracks found in wooden posts and beams are due to shrinkage as wood dries, occur along the grain, and do not raise a structural concern.
How long will a treated 6x6 post last in concrete?
A PT post will last a long time in concrete, maybe 5 to 10 years in soil alone. I suggest you embed the post in concrete, trowel a peak around the post so water runs off, and don't let the PT post come in contact with the ground.
Should pressure treated posts be set in concrete?
With pressure-treated posts, the rot will be slow. We have three ways to solve the rotten post problem. First, the posts should be set on top of a bed of coarse gravel 3 to 6 inches deep, so the base of the post is in contact with the gravel. Concrete should be poured around the post - no concrete under the post.
What lasts longer cedar or pressure treated wood?
When it comes to comparing treated wood vs. cedar, pressure-treated wood is the sturdier and more weather-proof of the two. It's highly resistant to insect attack and rot, and special versions rated for “ground contact” can be buried in soil and will continue to shrug off decay for decades.
