![]() ![]() Orienting defects to the sides, not the top or bottom face improves the strength. Wood that is stamped ‘clear’ doesn’t have those defects, and will be stronger than those that do. Knots, splits, cracks, and holes, regardless of the timber’s grade, affect the carrying strength. Curved or wandering grain lines aren’t as strong, so span distances are based on the weakest possible orientation, not the strongest. The greatest force can be applied end to end or parallel to the grain. Douglas Fir-Larch (DF-L), Hemlock-Fir (H-F), and Spruce-Pine-Fir (S-P-F) span similar distances to Redwood, Cedar, Ponderosa Pine, or Red Pine.Ī 6×6 is 5-1/2”x5-1/2”, so it can be rotated to align so the best grain direction surface is carrying the load. Southern Pine (SP) 6圆s will span 5” to 8” further than other common softwood species of the same grade. The distance a 6×6 can span as a beam depends on the species of wood, grade, grain orientation, moisture content or seasoning, condition, and load. How Far Can A 6X6 Beam Span Without Support?
