To better utilize the vast fast-growing forest resources in China， the bending properties of glulam made from domestically produced machine graded laminas of fast-growing Chinese fir were studied. The results show that the production of laminas with strength grade M22 and M18 accounts for more than 80%. The bending properties of glulam are significantly influenced by the grade and lay-up methods of the laminas， and the coefficient of variation of the bending properties is significantly reduced compared to individual lamina. The highest strength grade of glulam made by domestic fast-growing Chinese fir is TC_T40， in which TC_T32 or TC_YD32 account for most of the production， and the design value of bending strength exceeds the value specified in GB 50005—2017 Standard for Design of Timber Structures.
