Redwood Grades

Redwood lumber comes in over 30 different grades. This includes general-purpose grades as well as specialized grades for a single use. The criteria for grading, as defined by the Redwood Inspection Service, include appearance and durability. There is a grade of redwood for almost any application. Here are the factors to be considered when grading Redwood:


This is a major factor in the grading of redwood. If the lumber is clear (free from knots), it gets the highest grades. Other factors that affect grades are number, size, and nature of knots. Characteristics like stains, crooks, or manufacturing defects are also taken into consideration.

The color of a piece of redwood lumber determines its durability and resistance against insects and decay. For instance, reddish brown heartwood from the inner portion of a tree contains extractives that make it impervious to decay. On the other hand, cream-colored sapwood, which develops in the outer growth layer of a tree, does not have this quality.

Architectural Use: 

Some grades of redwood are especially suited for exterior and interior architectural uses. The following grades are sold dried (preshrunk and stress-free) for this purpose:

  • B Grade
  • Clear
  • Clear All Heart
  • Heart B
  • Heart Clear

When it comes to beauty and dimensional stability, no other wood type equals these finish grades. They are the ideal grades for siding, paneling, trim, and cabinetry where attractiveness and tight joinery are desired.

Garden Use:

Redwood grades that have knots as well as other characteristics that may make them unsuitable for architecture, are often used for decks, fences, and garden structures. The following grades are offered seasoned or unseasoned:

  • Construction Common
  • Construction Heart
  • Deck Common
  • Deck Heart
  • Merchantable
  • Merchantable Heart

The more durable heartwood grades are ideal for uses where the wood will be on or near soil. They can be used to create posts, bulkheads, or patio grids. Examples of these heartwood grades are:

  • Clear All Heart
  • Construction Heart
  • Deck Heart
  • Heart B
  • Merchantable Heart

When using wood for construction above ground, one of the sapwood-containing grades are ideal. This is because, during construction, there is little danger of insect or decay problems. Examples of grades that are beneficial for this use include:

  • B Grade
  • Clear
  • Construction Common
  • Deck Common
  • Merchantable

Redwood Patterns

Redwood pattern profiles are established by the Redwood Inspection Service. These profiles and dimensions help simplify the specifying and ordering of pattern lumber. Patterns are established based on:

Surface Texture: Pattern lumber or lumber that is shaped to a molded form can either be smooth-planed or saw-textured.

Grain: Redwood sidings can be sold as vertical grain (VG), flat grain (FG) or mixed grain (MG).
