First of all, we should know that using high-quality anti-corrosion wood in outdoor environments, long-term use will definitely cause cracking, deformation and other conditions, so there is no way to avoid this feature. Before installing this wood, special anti-corrosion impregnation treatment and kiln drying Processing, which will help the structure of wood cells to be more stable. And it can effectively reduce cracking and deformation during later use. Secondly, we generally recommend consumers and commercial users to choose preservative wood produced by professional and conventional manufacturers This kind of anti-corrosion wood will be specially treated. The anti-corrosion wood produced by some small workshops on the market cannot effectively resist various outdoor variables. Third, after anti-corrosion impregnation treatment, it must be air-dried in an environment that meets the requirements. The outdoor environment may differ in many ways, which is a very important factor. Natural air-drying can help stabilize the overall cellular structure of Pinus australis, thereby making this prevention possible. Decaying wood can minimize cracking and deformation.
