P.O.A
Hardwood is an excellent choice for fencing and landscaping projects that do not require structural ratings. Thanks to its H4 treatment, this hardwood post is ideal for fencing, as it can be placed directly in the ground.
Renowned for their durability and resistance to rot, decay, and insect damage, hardwood posts undergo an H4 treatment process to enhance their longevity. This process involves impregnating the wood with protective chemicals. The timber is placed in a pressure vessel, where a vacuum removes air from the wood cells. It is then subjected to high-pressure treatment, forcing the preservative deep into the wood. After soaking to ensure full penetration, the timber is dried, making it highly resilient for outdoor use.
