GE Frisco is able to source exotic lumber

Lumber for Marine Environments

We provide lumber that is safe to use in marine environments! We have treated wood that can be used for both saltwater splash and saltwater submersion. We supply this lumber in various different shapes and sizes including piling!

Sizes Offered



  • Ranging from 8-12” butts in 10’ to 60’ in length


We stock 3×8-3×12 that can be used for bulkheads and piers. Additionally, we are able to source and supply specific sizes that our customers would require.


What is the difference between saltwater splash and saltwater submersion?

  • Salt water splash: Lumber treated to withstand some contact with salt water.
  • Salt water submersion: Lumber treated to withstand constant contact with saltwater.

What is Piling?

Piling is cylindrical shaped treated lumber that has many uses. Some of the more common uses for piling include telephone poles as well as pillars for docks

Can I use marine grade lumber for other uses, such as decking or fencing?

Technically, yes you can, however we do not recommend doing so. Marine grade lumber is typically more expensive than normal pressure treated lumber and most outdoor projects can be easily done using pressure treated lumber. It is possible to have special circumstances where marine grade lumber may be more beneficial to use for your project, however, we recommend that you speak with one of our knowledgeable team members to come up with the best option for you.

How do I know what level of salt protection to get?

The requirements are set forth by the American Wood Preservers Association (AWPA) and is dependent on the location. Regions that are warmer and further in the US require a higher level of treatment than marine application in northern states.

What chemical is used for marine application?

The most common chemical used for salt water submersion is CCA. This is suitable and safe for any water application. However, it is not to be used for general residential application that is not on the water. In these scenarios, MCA would be the preferred chemical.

I need a supplier that is FSC Certified.
