Great question! Yes, the wood on our park benches is treated to resist both rot and insects. Outdoor furniture takes a beating from rain, humidity, ground contact and pests, so we choose and treat the timber specifically for long outdoor life.
For most of our standard benches, we use pressure-treated pine. The pressure treatment forces preservative deep into the wood fibers, creating a barrier against fungal decay and wood-boring insects like termites and carpenter ants. This is the same type of treatment used for fence posts and decking, so it is built to handle damp conditions and regular ground contact.
For premium or coastal park benches, we often recommend naturally rot-resistant species such as cedar, teak, or white oak. These woods contain natural oils and tannins that insects avoid and fungi struggle to break down. They still benefit from a quality exterior sealant or oil, but they start with much higher natural durability.
After machining and assembly, we apply a weather-resistant finish to the exposed surfaces. This top coat helps slow moisture absorption, reduces cracking and warping, and gives the bench a clean, finished look. We also use stainless steel or zinc-coated hardware to prevent rust.
Maintenance still matters. Even treated wood benefits from occasional cleaning and re-oiling or resealing every year or two, especially in very wet or humid climates. If the bench sits directly on grass or soil, keeping the feet on hard pads or gravel can also reduce moisture wicking.
So in short: yes, the wood is treated to resist rot and insects, and we match the timber and treatment to your local climate and how the bench will be used. If you need a specific treatment spec for a tender or landscape plan, just ask and we can send the datasheet.
