No.1
and Better

Bridges, decks, warehouses and all heavy construction where superior strength is required. Exposed framing where fine appearance is demanded. Graded primarily for members stressed in bending but also used as tension and compression members.

Columns, posts and struts in heavy construction such as warehouses, docks and other large structures where superior strength is required. Exposed framing where fine appearance is demanded. Graded for structural members in compression parallel to grain but may also be used in tension or bending.

No.2
Structural

Ranks only slightly below Select Structural in strength and appearance. Similar uses where high strength is required but appearance is less important.

Ranks only slightly below Select Structural. Similar uses where high strength is required but appearance is less important. Graded primarily for structural members parallel to grain but may also be used in tension or bending.
