been established by the California
Redwood Association. Most are
illustrated in CRA literature—
Redwood
Lumber Patterns No.17, Redwood
Architectural Guide
and Redwood Siding
Patterns and Applications
—and are
available from the CRA.
Grains
Vertical Lumber milled so that a cross
section of the annual growth rings
appears with grain lines parallel on face
of board.
Flat Lumber cut tangent to annual
growth rings exposing a face highly
figured or “marbled”.
Other grades will be shipped with a
mixture of vertical and flat grains. Clear
All Heart and Clear may be specified in

Flat Grain
Textures
Surfaced Unless otherwise specified,
redwood lumber, boards and patterns are
sold with a smooth-planed surface,
emphasizing the wood’s beauty of grain
and color.
Saw-textured One or more faces
can be resawn for a rough texture effect.
The saw-textured surface increases
redwood’s natural finish-holding ability,
resists or obscures smudges and scuffs
and is recommended for exterior siding
and less formal interior applications.
Surfaced
Saw-textured

Standard grademarks include grade
name and symbol of authorized grading
agency. Grademarks may be on
seasoned or unseasoned lumber on
face, edge or end of piece. “Certified Kiln
Dried” marks lumber kiln dried to
accepted RIS standards.
