Executive summary
In terms of bending stiffness, the C. ovensii achieved the SG6 structural grade, in terms of bending strength, the C. ovensii achieved the SG10 structural grade resulting in an overall grade of SG6.
To assign a full structural grade the other strength properties tension, compression and shear need to be evaluated.
From the small clear testing there were very few obvious trends between height in tree, modulus of elasticity, modulus of rupture and nominal density across the inner and outer wood samples for the five trees assessed.
