Charltons use Wolmanit® CX pressure treated to UC4 level for all of our products including all softwood 5 bar and pedestrian gates. UC4 is normally used for wood in ground contact so our gates are treated to the highest level.
Wolmanit CX is a product range consisting of liquid, chromium free preservatives, based on inorganic copper and boron compounds, which are used preventively to combat wood-destroying fungi, including those causing soft rot, and insects, including termites. Extensive international testing has confirmed the effectiveness of Wolmanit CX.
Wolmanit CX is based on Copper HDO, a fungicide that has been successfully used in wood preservation for many years and has undergone some of the most intensive toxicological testing of any wood preserving fungicide in the world.
After their rapid fixation in the wood, the aqueous Wolmanit CX products are resistant to leaching and the elements and are not harmful to plants.
