RE: Wood Designation Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hem-Fir and S-P-F are species combinations (one grade of wood that may
encompass two or more individual species of tree that have identical or very
similar properties).

Hem-Fir may be one of several types of fir or Western Hemlock (note there is
a difference in Hem-Fir and Hem-Fir (north) which includes Western Hemlock
and Amabilis Fir only).

S-P-F refers to "spruce, pine, or fir" and may encompass several different
species of each.

You can refer to the NDS supplement for the exact species included in these
and other groups.

Hope this helps
Dan

What do the designations stamped "Hem-Fir" and "S-P-F" on stand for and mean
for purpose of wood design ?  I have an idea but cannot find this discussed
in the references I have. Thanks.
