Alaskan Yellow Cedar Timbers, Post and Beam

Alaskan Yellow Cedar

Scientific Name: Chamaecyparis nootkatensis

Alaskan Yellow Cedar is quite a versatile species of lumber that can easily be used in any project.

This species of wood can be used for decks, siding, trim, ceiling, paneling, floors, doorscustom woodworking, and millwork. Its durability and ease of tooling makes it readily adaptable for the construction and finishing of homes, schools, factories, churches, and recreational centers along with a variety of other residential, commercial and industrial uses.

Found only on the Pacific coast of North America, Yellow Cedar is the hardest known cedar in the world.

Prized by boat builders, it has exceptional resistance to weather and insects as well as easy workability. First used by the West Coast Indians for their historic Totem Poles and great war canoes, it is a rare and often difficult to find lumber species.

Alaskan Yellow Cedar is very popular for carving as well as versatile when used in industrial applications. It has been traditionally used for boat building because of its long term durability. Racing boat enthusiasts have often used it for high performance shells, and for bridge decking. It stands up to constant wear and load impacts without forming ridges or splitting. It does not splinter, so it is also used on stadium seating.

Lumber Sizing

When ordering your Cedar products it is important to understand lumber sizing.  Lumber is generally going to be sold on what is called Nominal Sizing rather than Net Sizing. An example of this would be to order a 2″x4″.   Though the board is nominally called a 2″x4″ its net size may be 1.5″ x 3.5″ if it has been surfaced on all four sides.   

If you need a particular net size of material, please be sure to make your sales representative aware of the exact net size so he can provide you with the right piece of lumber.

Common Yellow Cedar Lumber Grades Available

Note: all pictures are meant for a general grade description.  If you want to see a more defined grade image, please let us know.  We can email you pictures and grade rules.


Clear Vertical Grain – Pieces may exhibit a few minor characteristics which do not detract from their high appearance and quality.  Limiting provisions include:  very light torn grain, very light skips on the non-graded face and very light warp.

A & Better Clear – Ideally suited to applications where finishing requirements are less exacting.  Limiting provisions include: small seasoning checks , occasional very light skips on edges and backs. Allows for two small, sound tight knots or their equivalent

C and Better Clear -This grade accounts for pieces of lumber having one or more characteristics which are of such size and number that the piece is not of C & BTR grade. Medium pitch streaks, limited pin holes, hit and miss skips, two knots approximately 1″ or their equivalent

D and Better Clear – Clear grains but allowances for medium pitch streaks, limited pin holes, hit and miss skips, two knots approximately 1″ or their equivalent.

Select Tight Knot – The basis for this grade are the knots, burls and naturally occurring markings which are of fairly uniform distribution and add to the decorative character of the piece. Sound, tight knots: star checked and/or slightly chipped knots permitted.

Bear Creek Lumber can offer other grades depending on the type of product ordered.  

Boards, timbers, paneling, bevel, etc all have slight variations to their grades, so it is important to understand what you are ordering.  If you are not certain on the grade you are being quoted, feel free to ask your sales representative for additional information. 

It is also important to be aware that if you are getting quotes on different grades of the same product that you are sure which grade you are purchasing at the time of sale.  Each grade has different characteristics and allowances for trim backs, so when you sign your purchase agreement it is imperative that you understand which grade you are going to be receiving.

Note the different colors above (some boards have been finished). Yellow cedar, like any other wood, has a range of colors from soft yellow to light brown.

Finishing Alaskan Yellow Cedar

Although Alaskan Yellow Cedar is naturally durable, a surface coat is recommended to protect the wood and extend its service life.  When selecting a finish coat, make sure it contains the following: water repellent, Fungicide/Mildwcide, Protection against ultra violet light.  Penetrating oil-based products, particularly those containing pigments, are recommended for Cedar.  Pigments provide increased UV protection. 

Importance of Stainless Steel Nails and Fasteners

Hot-dipped galvanized, aluminum and stainless steel nails are all corrosion-resistant and all can be used to nail Alaskan Yellow Cedar. 

Other types of nails, such as electro-plated, are not recommended.  They can rust and disintegrate and react adversely with the natural preservative oils present in Cedar, resulting in stains and streaks.  Copper nails also react with Cedar and should not be used.   Stainless steel is the best choice but hot-dipped galvanized is the most widely used and economical.

Below is an example of a contractor that used regular nails on an Atlantic coast home, with Alaskan Yellow cedar 1″x3″ Tongue and Groove siding.

The contractor erroneously thought that blind nailing the TnG would prevent the nails from corroding. The pictures show that corrosion has started, and streaks seem to come from the wood. Alaskan Yellow Cedar has tannins in its fibers that react with untreated steel, resulting in these black marks.

Although some people may find these “zebra” streaks somewhat attractive, we must remember that behind this wood there is a corroding fastener that eventually would need replacement. Remember to only use stainless steel fasteners with Alaskan Yellow Cedar products.

Alaskan Yellow Cedar grows in a band from Southern Alaska to Southern Oregon. It is one of the slowest growing trees in North America and includes trees that are 700-1200 years old. 50-60 annual rings per inch are not uncommon. 

This rare and exceptionally beautiful wood species seeks out high and adventurous sites and often grows to the tree line. It is a medium sized tree, with a thin bark. It is slow growing with high disease and decay resistance, as well as oils that make it very aromatic. It grows from Alaska south to Oregon with the largest areas of growth in British Columbia and SE Alaska. Other common names: Nootka cypress, sitka cypress, pacific yellow cedar.
