GRADING GUIDELINES FOR RADIATA PINE

No.1 Clear Grade

Clear on all four faces with the occasional minor blemish permissible as per N.Z. Timber Grading Rules NZS 3631:1988. Typical end uses include mouldings, dressed boards, panelling, and products that require a stained finish.

Prem Grade

A near clear grade used in decking which allows for a small number of tight defects on the best face and edges. Backface allows occasional large or broken knot defects and some hit and miss dressing.

SG8 Dry

SG8 dry is a structural grade ex pruned log that allows tight and live knot defects. Suitable for Lintels, floor joists, roof beams, general framing, trusses, decking joists, Verandah posts, Pergola and other outdoor applications.

Merchant Grade

Grading allows for a small amount of pith (less than 10% of the length), cone hole, needle trace, light to moderate resin, light blue stain and wane on up to 30% of the edge. Cluster and spike knots are allowed as long as structurally sound. Grading does not allow pith (greater than 10% of length), dead knots, decaying timber and broken pieces.

Industrial OR Boxing Grade
