The authors developed a new sawing method named hexagon-cut technology for small diameter logs.The sawing procedure and key techniques of this new method were described.With this new sawing method（finger joining,composing,and pressing）,small diameter logs could be made into large hexagon glulam beams for wood structural applications.The wood utilization efficiency of hexagon sawing technology can reach up to 80% which is much higher than other conventional sawing methods.
