Dockside Marine Supply supplies piling and timbers treated to endure marine environments. 

Treatment

Marine lumber is treated with Chromated Copper Arsenate (CCA).  In New Jersey, the standard level of treatment is 2.5 lbs CCA per cubic foot for salt water immersion and 1.0 lbs for foundation use, fresh water immersion or salt water splash. 

Measurements

Piling is often designated by the minimum diameter of the butt end of the pole for residential applications, but may also be listed by the diameter of the tip or by class, which specifies several measurements.  Timbers follow standard lumber conventions and are quoted in rough dimensions; for example, a 6” x 6” timber will measure approximately 5 ½” x 5 ½”. What we stock.

Disposal of Treated Lumber

• Reuse treated wood to the extent possible
• Do not dispose of CCA-treated wood remnants or sawdust in compost heaps, wood chips or mulch; chemicals from the preservatives may enter the food chain.
• Dispose of construction waste or materials removed from service in accordance with local regulations. Contact your municipality or provincial government to find out how to dispose of CCA-treated lumber in your area. (Most areas use ordinary trash collection or burial).
• NEVER BURN TREATED WOOD. Arsenic and chromium may be released into the environment as part of the smoke or remain in the ashes.
