Fences are treated under pressure because wood is known to be the best building material, until the time it stays dry, but it does not last for long time if it gets wets as it might get damaged, and can encounter fungus and insects. We can coat this wood with some fungicides or with some preservatives, but this coating will not reach deep inside the wood, it remains only on the surface of the wood.

For pressure treated fence posts, wood is submerged in tank filled with chemical preservatives; this tank is then heated on high pressure. This pressure forces the chemical to enter deep inside the wood; this helps wood to survive for long years and to be free from insects and fungus. Pressure treated wood is costly as compared to the non-pressurized wood, as the pressurized wood stays for long time in comparison to the non- pressurized wood.

It is also a problem that the non-pressurized wood is more attractive, fancy, and of low costs, as compared to the pressurized wood. The decision of buying pressure treated fence posts seems to be a wise decision as it stays long and is the right choice to select. The ultra violet sun rays damages the wood, and turn the wood grey but it affects the pressurized wood very slowly.

One should take certain precautions, while working with the pressure treated wood, he/she should wear a dust mask while cutting the wood, and wear gloves while handling the pressure treated wood fence. The chemical used to pressurize the wood is poisonous, which one should not breathe in to the body. This pressure treated wood should not be burnt because it gives out a nasty smell and smoke, which can be choking too. There are especially designed nails and screws for pressure treated wood, which one should use while working on the woods.

Some of the chemicals used are too poisonous and too acidic in nature and they can destroy nails and screws if not properly used. One should be sure, that the wood he is using is right for the job. There are different kinds of pressure treated fence posts, some are built for being exposed to weather, some are for burial, and some other are rated for contact with saline water.

Number of dissimilar varieties of pressure treated wood is accessible like CBA, ACQ, and CCA etc. It is important for a person to know about the kind and the quality of pressurized wood he/she is using according to the needs of the job. Different people have different comments about the pressurized wood; some think that the quality of wood has become advanced.

Pressure treated lumber in the market uses copper whereas primarily arsenic was used for treating wood. The color of chemical of the pressure treated wood becomes greenish if it is treated with copper; it is the chemical, which can keep the wood good looking even in sun, snow and rain for years. The quality of the pressurized wood has risen with time and innovations.
