|
No.3 |
Assigned design values meet a wide range of
design
requirements. Recommended for general construction purposes where appearance is not a
controlling factor. Many pieces included in this grade would qualify as No.2 except for a
single limiting characteristic. |
|
Stud |
Suitable for stud uses including use in
load-bearing walls. Composite of No.3 strength and No.1 nailing edge characteristics. |

Recommended for general framing purpose. Good
appearance, but graded primarily for strength and serviceability. |
|
*Standard 2" to 4" wide only) |
Recommended for same purposes as Construction
grade. Characteristics are limited to provide good strength and Excellent serviceability. |
|
*Utility (2" to 4" wide only) |

construction and good strength is desired. Used for such purposes as studding, blocking,
plates, bracing and rafters. |
|
Design values are not Assigned Economy |
Usable lengths suitable for bracing, blocking,
bulk heading and other utility purposes where strength and appearance are not controlling
factors. |
