Pressure Treated Wood

pressure treated wood deckCoastal Lumber specializes in lumber of all types for your outdoor building uses and we are one of the best sources in the Bay Area for pressure treated wood.

Pressure treatment is a process that forces chemical preservatives into the wood. Waterborne, Creosote, and Oil-borne (penta) are the three broad classes of preservatives typically used when pressure-treating wood and woods treated with waterborne preservatives are commonly used in residential, commercial and industrial building structures.

Insect and Weather Resistant

The most important thing to understand about pressure treatment is that it is by far the best way to avoid harmful rot and insects. While older pressure-treated wood must be periodically treated with a sealant to lock in the dangerous arsenic chemicals, newer pressure-treated must also be coated with sealant to protect the wood from weathering and corrosion.

Wood species such as Douglas Fir have more heartwood and proper modifications are made to the preservative to achieve adequate penetration and retention levels. Coastal Lumber carries primarily pressure treated Douglas Fir.

Durable with an Excellent Finished Appearance

When working with pressure treated wood, hot-dip galvanized, stainless steel or corrosion-resistant wood fasteners should be used to protect against corrosion and premature wear. The finished product must be protected from moisture and sun damage, and, the project must be built safely in accordance with state and local building codes.

Before beginning your outdoor construction project using pressure treated wood, please make sure to ask our staff at Coastal Lumber about building tips, consumer information, handling precautions, and care and maintenance recommendations. You’ll want to be sure to follow quality craftsman guidelines for an excellent finished appearance and durability.
