Coast Forest: Products - Product Directory

Coast mills produce a wide range of products in Construction grades. It is not uncommon to manufacture to customer’s in-house standards. There are some specialty products such as siding and decking produced from the knotty fiber. However, the greatest volume of construction lumber is manufactured to one of the three grading rules (NLGA, Coast Forest or PLIB) described previously. The choice of rule normally will depend on the intended end use of the product. Specifically, whether a structural product with known engineering properties is required or whether the wood is intended for remanufacture or general construction where strength is not critical. The type of construction lumber graded under each of the rules is described below. The grades are summarized in Table 4 and illustrated on pages 18 to 25.

NLGA - For rough or dressed lumber, unseasoned or kiln dried, all species and all sizes from nominal 2"x2" to 12"x12". All structural lumber is stress graded and intended for use in the size shipped (except for cross cutting for length). NLGA stock can be remanufactured into smaller cross sections but not without invalidating the grade and strength ratings. It is the most common grading rule used. The stress grades are those developed for the North American housing and construction markets.

Coast Forest-JPS 1 - Only for the metric sizes of Hem-Fir (N) used in post and beam housing. There is one grade (E 120). All lumber manufactured to this standard is stress graded with known engineering properties. Not normally available in thickness greater than 120mm.

PLIB R-List - For rough or dressed lumber, unseasoned or kiln dried, all species and all sizes up to 12"x12". Often specified if lumber is to be remanufactured into smaller sizes or used as is for non-structural applications.

Grade Rule	Grade	Description and Recommended Use
NLGA	Light Framing	General framing lumber in size up to 4"x4".
	Standard adn Better	Studs, plates and rafters in wood frame construction. Also used for general construction.
	Utility	Studs, blacking, bracing in wood frame construction. Also used for general and/or temporary construction plus packaging, pallets and other industrial uses.
	Structural Light Framing and Joists and Planks	Stress graded lumber intended for structurally designed applications. Up to 4" in thickness and 12" in width.
	No2 and Better	Structual members in wood frame or general construction where high strength properties are required such as joists, rafters, trusses and beams.
	No.3	General construction where appearance and high strength are not critical as well as industrial/remanufacturing uses such as packaging and pallets.
Coast Forest JPS1	E-120	Stress granded metric sized structural lumber intended for post and beam residential house construction. Also suited for a wide range of industrial applications.
PLIB R-List	Merchantable Lumber	Construction type lumber intended for use as is where structural design stresses are not required and/or where it is to be remanufactured and re-graded to other grading rules.
	Salect Merchantable and No.1 Merchantable	Inrtended for remanufacturing and/or general construction where a sound, strong, good quality of knotty wood fiber is desired.
	No.2 Merchantable	Similar to Select and No.1 grades except allowing slightly larger knots and other growth characteristics.
	No.3 Merchantable	A Utility type grade suitable for temporary construction and industrial remanufacturing.

Grades	Recommended Uses
Beams and Stringers(Rectangular Timbers)
No.1 and Better	Bridges, desk, 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.
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.
Standard	General construction and mine timbering.
Utility	Temporary heavy construction and shoring.
Posts and Timbers(Square Timbers)
No.1 and Better	Columns, Posts and struts in heavy construction such as warehouses, docks and other large structures where superior strength is ewquired. 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. Similar uses where high strength is required but appearance is less important. Granded primarily for structural members parallel to grain but may also be used in tension or bending.
Standard	General construction and mine timbering.
Utility	Temporary heavy construction and shoring.
