Concerning CCA Poles
If you are in the wood business you will most likely know very well what CCA poles are. If you’re not in the timber industry you’ve most likely seen cca poles however did not know it at the time. Let’s have a look.
CCA is short for chromate copper arsenic. It is a preservative used in treating wood poles. Hence the actual cca poles. The actual copper is used as a fungicide to protect the poles from being damaged by a range of fungi. The arsenic is an insecticide which will stop harmful termites as well as borer bees and other bugs for compromising the actual integrity of the poles. The chromium that’s implied in the “chromate” portion of CCA is used to protect the poles from ultra-violet light.
The soon to be CCA poles are treated in a pressure treatment and vacuum procedure. When the wood has been completely treated it’s stack up to dry out. The quantity of stress that’s applied will determine just how much CCA is imparted in to the poles. The more CCA that goes into the poles the more guarded they will be.
There is concern that cca poles may leach the harmful chemicals that they are treated with in to the environment and also evidence has been found of this, especially where the soil has a large clay content or perhaps an alkaline ph. Some countries have limited the usage of CCA poles within residential and commercial areas as a result of these kinds of studies.
There has also been evidence that individuals that come into contact with CCA poles on a regular basis are exposed to higher levels of arsenic than is safe. It is because of this that CCA poles aren’t permitted to be used in playground equipment or even hand rails along with other stuff that individuals come into contact with on a regular basis in Australia.
The fact remains however that CCA is a great additive for wood poles and still has its own place in construction. The majority of the commercially sold poles will be creosote treated though to avoid people from using CCA poles within home construction. It is not illegal to treat poles with CCA you just have to use them within the proper environment.
If you are going to be setting up phone poles in a rural area or even industrial area where atmospheric contaminants are high then you’re more likely to use CCA poles so that they will endure the environment better. If you are going to be doing wood building within a residential region or perhaps a commercial region you are going to need to make use of other sorts of poles which have not really been treated with arsenic.
As time goes on there’ll most likely be other chemical treatments which will replace CCA treatment. Until then it’s still one of the best methods to make sure that your poles are not likely to be eaten by bugs or even damaged by fungi along with other nasty things like that. Therefore until a brand new procedure comes about that’s just as efficient we will have CCA poles.
