Pressure Treated vs. Dip Treated

There are two main types of treatment that are commonly used with timber fencing and fence panels. These are dip treated and pressure treated. Both of these treatments are very effective but here we will point out the most important differences.

Dip treated panels

These are often a darker brown or golden colour. The dip treating process is fairly quick to do, meaning the price is usually lower than pressure treatment , which takes much longer. However, dip treatment does not last quite as long and may require additional applications of a brush on preservative in order to give the timber the longest life possible.

Pressure treatment

This is a method that forces preservatives into the timber, right through to the middle. It’s done by putting the timber in a vacuum and then large amounts of pressure applied to force the chemical preservatives in. These preservatives, like those in dip treatment, are very effective against insects and fungal decay. However, pressure treated timber will, on average, last a bit longer than dip treated. Therefore, this kind of timber will be slightly more expensive than dip treated initially, but you need to weigh up the importance to you of the initial costs against the length of time you expect the timber to last.
