How to Choose the Right Redwood Lumber for Your Project
Few building materials bring the warmth and character of natural wood to an outdoor space like redwood lumber. Its rich color, distinctive grain, workability, and outdoor performance make it a sought-after material for decks, fences, benches, garden structures, and architectural details throughout the Bay Area.
Choosing the right redwood starts with understanding the differences between available products. Heartwood content, grade, surface texture, moisture condition, dimensions, and intended use can all influence how the finished project looks and performs. Backed by four generations of building material experience, O.K. Lumber Co. helps contractors, builders, and homeowners compare Heart B decking, S4S redwood, rough green lumber, and dry redwood so they can select the right material with confidence.
Why Is Redwood Lumber Used for Outdoor Projects?
Redwood is a lightweight, workable softwood that cuts and fastens easily. It can be left to weather naturally or finished to help preserve and enhance its color.
The part of the tree from which a board is milled affects performance. Redwood heartwood contains natural extractives associated with resistance to decay, while sapwood does not offer the same natural durability. USDA Forest Service research identifies heartwood decay resistance and dimensional stability as reasons redwood has traditionally been used for decking, siding, fencing, and posts.
Buyers should consider heartwood content, grade, knots, moisture, dimensions, and surface preparation rather than choosing a product based solely on the word “redwood.”
H2: What Should You Consider When Buying Redwood Lumber?
The best redwood lumber is the material that matches the application. Before ordering, consider the following factors.
Redwood Grade and Appearance
Redwood grades vary in knot size, color, and heartwood content. Clearer grades provide a more uniform appearance, while knotty grades display more natural character. A visible bench or trim detail may call for a different grade than a fence post or rustic garden structure.
Heart B redwood offers an appealing option for decking. Its small, tight knots add natural character, while its all-red heartwood color creates a warm, cohesive surface.
Surface Texture
S4S means a board has been surfaced on four sides, creating a smoother and more uniform profile. Rough redwood retains a textured, saw-cut surface suited to rustic designs, fences, posts, and landscape structures.
Consider whether the material will remain visible in the finished project. Smooth S4S redwood may be preferable for benches, trim, screens, and detailed features, while rough lumber can complement projects where a more natural texture is desired.
Green or Dry Redwood
Green redwood has a higher moisture content and may move as it dries. Dry redwood provides greater dimensional consistency at installation, which can benefit detailed work and projects where a predictable fit matters.
The appropriate choice depends on the application, installation method, and project schedule. O.K. Lumber can help you compare current green and dry redwood options before placing an order.
Dimensions and Lengths
Confirm dimensions, profiles, quantities, and lengths before purchasing. O.K. Lumber lists products ranging from 1x1 rough redwood and 2x2 S4S material to 2x12 boards and larger 4x4, 4x6, 4x8, and 6x6 options.
Available lengths and quantities vary by product. Checking inventory before completing your material list can prevent unnecessary cuts, waste, and project delays.

Heart B Redwood Decking for Outdoor Living Spaces
Heart B redwood decking is a premium natural wood decking option at O.K. Lumber. Its small, tight knots and all-red coloring provide natural warmth without the highly varied appearance of boards containing more sapwood or larger knots.
Milled from heartwood, Heart B offers natural resistance to decay and insects along with the workability and dimensional stability associated with quality redwood. It is well suited for deck boards, stairs, built-in benches, and other outdoor features designed to coordinate with the main deck surface.
Stair components, fascia, railings, fasteners, board spacing, drainage, ventilation, and finishing choices also affect the completed deck. O.K. Lumber can help customers review their material lists and compare suitable redwood profiles. Structural requirements, spans, exposure, and local building codes should guide the final selection.

No. Redwood is botanically classified as a softwood, although quality redwood heartwood is valued for its outdoor durability, stability, and appearance.
-
Yes, the appropriate redwood grade can be an excellent decking material. O.K. Lumber’s Heart B decking features all-red heartwood color and small, tight knots suited to deck boards, stairs, and benches.
-
S4S means the lumber has been surfaced on all four sides. This creates a smoother and more consistent board profile than rough-sawn redwood.
-
Green redwood contains more moisture and may move as it dries. Dry redwood has a lower moisture content, which generally provides greater dimensional consistency during installation.
-
Redwood lumber prices depend on grade, heartwood content, surface preparation, dimensions, length, quantity, and current availability. Requesting a quote based on a complete material list will provide a more useful estimate than comparing a single per-board price.
