Deck Lumber and Boards

Once the location and design for a new Humboldt Redwood deck have been chosen, it is time to determine the redwood building materials you will use. Before running out to your nearest Humboldt Redwood dealer, you’ll need the right products to make sure the best deck is built – starting with a solid deck wood.

The best wood for decks should have considerable strength for structural stability, be weather resistant, and be durable enough to last for years and years.

Humboldt Redwood is one of nature’s finest and strongest building materials with shear strength up to five times greater than plastic composite decks. All this strength and durability comes packaged in a lightweight wood that’s easy to work with, which helps to keep construction costs low. On top of all these benefits, Humboldt Redwood deck wood is an attractive material. It’s rich, warm color and grain pattern will look great even as it ages.

If you’re considering redwood for your deck project, take a look at the quality products below to learn more about what Humboldt Redwood has to offer. There are several factors to keep in mind when choosing Humboldt Redwood lumber and deck boards – namely, the grade, board size, and finish.

Redwood Grades

Did you know there are more than 30 types of Redwood grades? The term “grade” refers to both the durability and the appearance of the lumber. Lumber grades are determined using criteria outlined by the Redwood Inspection Service (RIS). The grades help determine the best use for Redwood based on its durability and appearance.

Understanding the durability of the wood is important because it helps determine the best use for the lumber (e.g. ground-contact vs. above-ground, substructure vs. surface, etc.). And appearance is particularly important in the case of redwood because it has so many variations in color and the presence of knots.

Our section on Redwood Grades has a wealth of information that can help you choose the grade of deck wood that will work best for your project.


Redwood Deck Board Sizing

Once you know the grade you want to work with, choosing the right Humboldt Redwood deck boards is simply a matter of getting the right dimension. Sizing isn’t just about the square footage of a deck. You can create a unique look by using different lengths and widths of Humboldt Redwood deck boards.

If budget is of higher concern, less in-demand deck board lengths such as 8’, 10’, and 14’ can be more economical. By designing your deck to take advantage of these less popular deck board lengths, you can have a beautiful, unique deck at a more affordable cost per square foot. Contact your nearest Humboldt Redwood dealer for additional information and suggestions on the most economical deck board lengths available.

Humboldt Redwood deck boards are available in the following dimension, length, and grades:

Dimension Length Grades Available Finish Characteristics Available
2”x4” 6’ – 20’ Deck Common, Deck Heart, Selected Heart, Clear, B Grade, Heart B, Heart Clear S4S*
2”x6” 6’ – 20’ Deck Common, Deck Heart, Selected Heart, Clear, B Grade, Heart B, Heart Clear S4S*
*S4S = Surfaced Four Sides

Once you have your deck measurements you’re ready to buy Humboldt Redwood deck boards. If you’d like to see some boards in person, please contact your local lumber yard to learn more and have any last-minute questions answered.

Framing and Substructure

Humboldt Redwood has the strength needed to create a structure that will securely support your deck for years to come. However, there are other products that can be used beneath the Redwood surface if you’re on a budget. Allweather Wood Pressure Treated Lumber is an affordable substructure material that can be paired with Humboldt Redwood decking to create an outdoor space that’s cost effective, beautiful and solidly built.
