Lumber specifications on drawing

Lumber specifications on drawing

Lumber specifications on drawing

(OP)
I have a drawing of a 10000 pound capacity skid that I am trying to get built.  But the drawing specifies that the wood deck on top meets the following requirements.  Lumber specification: kiln dried; oak, hickory, or other approved grp.IV hardwood species.  Quality, as delivered, shall be equivalent to grade no. 1 common per national hardwood lumber assoc. rules subject to the following limitations.

A)  Minimum width and thickness as specified
B)  Knots must be tight, sound, and 3/4" dia. max.
C)  All material to be full cross section for full length.

How do if determine if the wood I get meets these requirements?  Can anyone translate these specs?

RE: Lumber specifications on drawing

Try the following web sites:

www.hardwood.org
www.natlhardwood.org

There's an awful lot of imformation on these web sites pertaining to hardwood specifications.
