TIMBERS In general, applications can be classified into two broad end use groups: first, for those structures such as large buildings in which both the strength and the appearance of exposed wood members are of equal importance; and second, in landscape, park and garden structures where appearance is paramount. For both use–groups, Western Red Cedar offers the advantages of natural beauty, design flexibility, exceptional dimensional stability and long term durability. Cedar has a long history of withstanding the rigors of time and weather. It is also a recognized structural material with known mechanical and physical properties(see WRCLA publication Designer's Handbook). These attributes allow the design of timber structures of all types using basic engineering principles and stress– or appearance– rated grades of Western Red Cedar. GRADES OF WESTERN RED CEDAR TIMBERS 
Grade: NO. 2 AND BETTER CLEAR Description This grade should be specifi ced when the finest quality rough lumber is desired. The lumber is sound and well manufactured. Its natural characteristics do not detract from the wood's fine appearacnce. Grading Rule Paragraph1 Export R List 401 
Grade: D AND BETTER CLEAR Description The C and better Clear grade offers good appearance in high quality, well manufactured lumber. Suitable for high quality landscape structures and as exposed posts and beams in heavy timber construction. In most cases, this grade is sold with a specified allowance of D grade. D Clear grade permits larger and more numerous natural characteristics which are widely accepted in the construction of outdoor structures. Some pieces of D Clear may require trimming to yield lengths for the intended use. Grading Rule Paragraph1 NLGA 203 b,c,d 
Grade: APPEARANCE KNOTTY Description A non structural product manufactured to meet the appearance requirements of quality projects. This materials has highly restricted wane allowances to give well defi ned corners. Contains no holes or other characteristics. Represents good value for appearance end uses. Available rough sawn or rougher headed in nominal 2" and thicker sizes. Note: Upon request, Appearance Knotty timbers are available with structural grading. Be certain to specify Appearance Knotty structural lumber when strength characteristics are required. Grading Rule Paragraph1 Proprietary 
Grade: NO. 2 AND BETTER STRUCTURAL Description Material of this grade is evaluated for structural strength characterisitics. The classification includes pieces meeting the grades of Select structural, No.1 Structural, and No.2 Structural. Lumber of this grade is intended for engineered applications where strength is more important than appearance. Available surfaced or rough textured. * Graded as Light Framing Grading Rule Paragraph1 5"and thicker, with more than 2" greater than thickness 
Grade: STANDARD BEAMS, POSTS AND TIMBERS Description Timbers of this grade are intended for general construction purposeswhere serviceability is more important than appearance. No Structural values are assigned. Available surfaced or rough textured. Grading Rule Paragraph1 5" and thicker 1NLGA - National Lumber Grades Authority Western Red Cedar Lumber Association |
