To use eucalyptus as solid wood products in value-added way instead of wood chips for pulp and paper, the sawing characteristics of E. grandis was studied, the strain changes in sawing process, bow deformation and end-splits of lumber were analyzed. The results showed that the sawing strain changed in a random way, but the bow deformation had an evident regularity, the lumber near its bark had a big bow deformation. The end-splits had severe influence to lumber recovery, 15% of lumber recovery was influenced by end-splits. The results also indicated that planted E. grandis was a potential wood species as solid wood utilization in the fast-growing plantation.
