How is the timber type and stress grade determined?
Grading methods Visual grading: stress grades determined by the inherent strength (strength group) of the species and the visual quality (grade) of the timber piece.
Why are wood sizes not the actual size?
The “nominal” cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S). The nominal measurement is made before the lumber is surfaced.
Is wood 2×4 or 4×2?
2×4 and 4×2 are the same thing, with both terms in widespread use. Metric sizes are also sold that don’t correspond to the popular imperial sizes. For rough sawn wood the nominal size is normally very close to the real size supplied.

Which one is stronger round timber or sawn timber?
Round timber can generally be considered stronger than sawn timber of the same section area, since the fibres in round timber are intact. The pole is normally tapered and therefore the smallest section area, the top end, must be used in calculation of compressive and tensile strength.
Is F17 better than F14?
F14 for example means that it can withstand a force of 14MPa without excessive deflection. F17 is stronger and so it goes up to F34 for some exceptionally strong species which have been kiln dried and are free of any defects.
