About Using Treated Wood For A Trellis
Most of the treated timber at your neighborhood hardware store will be pine. It is more than not a light color, which can sometimes look a little green after being treated. The main benefits of using treated pine start with its relatively low cost, when compared to other common timbers that are suitable for outdoor structures like cedar. This option will give you the least expensive pergola possible. So, if the cost is your primary concern, then the call has already been made and you are going to have a pine arbor, pergola or other garden structure. There are a few other factors involved in the decision for most people, though. One being the harm on the environment, because most treated wood, is treated with a three chemicals known as CCA, chrome, copper and arsenic, and arsenic being known to cause cancer. If you are a DIY type of person, then you will end up with this stuff in your airways after the project, and if your children will be playing on it then they will have it on their skin too. And, don't even think about growing berries on your garden arbor that's has been treated with CCA. In the treatment process, these chemicals are added to the wood, often, when it still has very high humidity. This plays a part in the cheaper price, because the factory doesn't have to dry it, but it also might lead to some cons in your garden structures like trellises. Improperly dried wood will change in shape considerably when dried, which can lead to bowing, warping and cracking in your garden structure. Having said that, treated timber is as of now pleasing many people out there that have built their back porches and garden using it as their wood.
But if treated timber isn't your cup of tea, then there are many other selections of wood for unique pergolas or even vinyl pergolas at Best Pergolas.
