Grain
Lumber has either flat or vertical grain.
Orders for Clear All Heart and Clear
may specify a grain. Garden grades are
shipped as mixed grain but can be field-
selected for desired use. When used for
deck surfaces, flat grain redwood should
be applied with the bark side up for best
performance. Vertical grain lumber will
provide the smoothest surface for railings
and benches.
Vertical Grain Flat Grain
Texture
Redwood is generally available surfaced
(S4S) or rough. Surfaced lumber is best
for decking or areas that are to be painted.
Seasoning
Unseasoned redwood is suitable for
most landscaping applications, but air-
seasoned or kiln dried redwood often
has a better appearance and provides
enhanced stability and finish retention.
Dry lumber is lightweight making it easy
to work with.
Specifying Redwood
To ensure delivery of the right lumber for
the purpose intended, the specification
should include: use, grade, grain,
seasoning, size and texture.
For example
Redwood lumber for (use) decking shall
bear the Redwood Inspection Service
grade mark and shall be (grade)
Construction Common, (seasoning)
unseasoned, (size) 2x6, (texture) S4S.
Redwood specifications should always
require the use of top-quality corrosion
resistant fasteners.
