Pressure-treated wood is wood that has been infused with chemical preservatives to protect the wood from rot and insects. The wood is placed in a depressurized holding tank that removes the air and replaces it with a preservative.
The problems with pressure treated wood, however, outweigh the benefits when building a new fence. One of the most common problems is warping and twisting.
As you can see in the pictures, these pressure treated 4x4's twisted at the top even though they had top and bottom fence plates holding them in place. This was not one post we replaced that was like this for a customer, it was the entire lot.
And, the fence was installed just under 8 years prior. Our difference is our post-on-pipe system. The pipe is embedded in concrete, not the wood. Our 4x4 cedar posts are then mounted on the post, ensuring minimal to zero wood rot, and if there is a problem in the future, we can simply swap out the cedar post, as the galvanized metal pipe in the ground will not rot or rust in our lifetimes.
This helps ensure our fence is the last fence you'll ever install!The posts have a lifetime of plus years. Farmers in the area made fences by laying them on top of one another in a diaganol line. Woodsmen cut the trees and hand hewed the lightered parts into posts and sold them all over the southeast.
As the older lightered trees were cut out; these same woodsmen started using heart cypress as posts and continued selling them in the Southeast area to cattle farmers. After the Cypress posts were no longer available Southern Pine trees were debarked and treated by dipping them into a barrel filled with creosote oil made from coal tar.
More modern mills were built which used a machine to peel these small trees and pressure treat them in a cylinder or retort under pressure. They had a peeling operation and a Creosote retort for pressure treating the posts. The posts were cut by small crews using a chainsaw and farm tractors. The suppressed trees from Southern yellow pine forstests were selected because they were very dense and straight and, therefore made an excellent fence post.
In another retort was installed to treat with CCA as the Creosote product was becoming more expensive.
After 1 year of learning the company crew made 10 loads per week. The equipment has been upgraded so that now we are making 35 loads per week. The equipment the harvesting crew uses measures the diameter and length of the trees before they are cut.
We program in a computer the sizes we are needing and the processing head cuts those sizes thus reducing our inventory and enabling us to respond to large orders in a timely fashion. Home Products Applications Contact Us.Why don't fictional characters say "goodbye" when they hang up a phone?

Pressure Treated Pole and Piling Chart.Some tree species contain chemical compounds in their wood that provide a natural resistance to the microorganisms that cause decay, and this natural resistance means that these wood species are more durable in terms of rot when they are used for outdoor building projects.
Among the most decay-resistant species are those in the cedar family, including Western red cedar and Eastern white cedar. The decay-fighting chemicals are in the greatest abundance in the tree's heartwood, the dense wood near the center of the trunk, and much less so in the sapwood in the outer part of the trunk.
Consequently, lumber made from heartwood is much more resistant to rot than is lumber that contains sapwoodwhich is not significantly more durable than nonresistant species.
In outdoor structures that are not in contact with the ground, such as decks, gazebos, pergolas and fence boards, cedar may last 30 years or longer. When in contact with the ground, such as when it's used for fence or support posts, it can last between 15 and 20 years.Ammoon looper firmware
Pressure-treated lumber is made from a non-decay-resistant wood, often Southern yellow pine, that is infused with a chemical treatment that prevents decay. In modern pressure-treated lumber, the most commonly used preservatives include alkaline copper quaternary ACQ and copper boron azole CBA. The lumber's longevity depends on how much preservative is in the wood, a characteristic that varies among grades of pressure-treated lumber.
For above-ground use, wood with 0. When the proper grade is used, pressure-treated lumber can last more than 20 years. The rating or grade of pressure-treated lumber is displayed on a grade stamp -- applied to the face of the lumber -- or on a tag stapled to the ends of boards.
Standard-grade lumber carries labels such as "Above-Ground" or "For Above Ground Use," while heavily treated lumber for ground contact is labeled "Ground Contact.Casita refrigerator
In terms of physical characteristics, cedar differs from pressure-treated lumber because of differences in wood species apart from their decay resistance. Red cedar is, for example, not as hard as yellow pine, making it more vulnerable to gouges and scratches when used in applications such as deck flooring.
The bending and compressive strengths of cedar are less than those of pine, too, which make it less capable in important structural roles. Cedar's principal advantages over pressure-treated lumber are its freedom from synthetic chemicals and its attractiveness. Those advantages come at a significant cost, however. The best grades of cedar, those that contain primarily heartwood and are free from cosmetic defects, typically cost several times as much as comparable pressure-treated lumber.
The cost varies regionally, though, and in areas where cedar is more prevalent, its cost will be lower, although never as low as that of pressure-treated pine.
Use the right fasteners: For cedar, use stainless steel or aluminum nails or screws. Neither of these will "bleed" dark streaks onto the wood. For pressure-treated lumber, use stainless steel or hot-dipped galvanized fasteners. Other types of galvanized fasteners are more prone to corroding in treated wood.

Show Comments.Pressure-treated lumber is a popular choice for building outdoor projects. Pressure-treated wood is made for use outdoors, where exposure to the elements can quickly rot untreated wood, and where damage from insects, such as termites, is common. The preservatives used in pressure-treated wood give it resistance to these things to make it last much longer outdoors.
Treated wood is mainly intended for landscaping and for building outdoor structures, such as fences and decks. People ask all the time whether you can or need to stain pressure-treated wood. One of the elements in pressure-treated wood that helps it resist the elements is copper. And copper is corrosive to other metals.
