CCA Treated Lumber for Highway Construction and Utility Poles

Central Nebraska & Iowa Wood Preservers are one of very few providers in the country qualified and certified to produce hundreds of different timber products and parts for government, public utilities, and transportation applications. Starting with 6′ x 8′ x 18′ lumber, we can cut and mill raw timber into any type of block or post needed, with custom pre-drilled hole formations.

Specifically, CCA treated wood offers widespread availability, easy handling and modification, long life, and low cost in a variety for highway applications. Treating requirements appear in AWPA Standard C14, with treatment of 0.60 pounds of CCA per cubic foot as most common and 0.50 pcf or 0.40 pcf also frequently specified. Whether for state government use, county needs, or use on local road projects, lumber is treated to a retention level specified by each governmental agency or municipality.
