Pressure Treated Lumber

Built to Resist the Elements

Pressure-treated lumber is specially infused with preservatives to help it stand up against rot, insects, and moisture — threats that quickly damage untreated wood. This treatment makes it the go-to choice for outdoor structures, ground-contact installations, and below-grade projects where durability is essential.

At Haselton Lumber, we stock a wide range of ground-contact rated, above-ground rated, and specialty treated posts and beams, ensuring you have the right level of protection for your specific project.

From decks and fences to retaining walls and dock supports, our treated lumber offers long-lasting performance and the reliability your projects demand.

Common Uses

• Ground Contact: Posts, retaining walls, landscape timbers.
• Above Ground: Deck framing, fence rails, pergolas.
• Marine/Dock Applications: Specially treated for constant water exposure.

Why Treatment Matters

• Rot Resistance: Extends the life of the wood by protecting against fungal decay.
• Insect Protection: Prevents termite and carpenter ant damage.
• Moisture Tolerance: Reduces swelling, shrinking, and splitting in wet conditions.
