The Eucalyptus punctata wood has a limited participation in the forestry sector. Grey gum, as this species is commercially known, remains underutilized in industry and forgotten in literature. Aligned with industry topic contained in the nineth Sustainable Development Goal (SDG 9), sixteen properties of Eucalyptus punctata plantation woods were investigated to identify its potential as an alternative sustainably-produced structural timber, with the support of the Brazilian code for wooden structures. In this strategy to scientifically evince the potential structural uses of Eucalyptus punctata, two moisture contents were adopted to elucidate green wood (initial point at 30%) and dried wood (standard point at 12%). In a typical sample process, 2299 determinations were carried out. Bulk density showed a statistical influence when moisture content is reduced from green to dried condition, indicating an expected decrease in its value. Thirteen mechanical properties manifested statistical influences and visible increases in their resistances, including all five properties of modulus of rupture and four properties of modulus of elasticity, as well as shear stress, perpendicular hardness, parallel hardness, and tangential cleavage. Good results in the comparison with different popular varieties of planted pines and eucalypts reinforce the potential of its structural purpose.
