The stem is very thick, strong and durable where the water content of 8% has a wood density of 0.7-0.8 g/cm3, the moisture content of 15% has a fracture firmness of 103 N/mm2, compressive firmness parallel to the direction of the fiber is 31 N/mm2 and firmness the shear is 7.3 N/mm2.

Betung bamboo is used as building material and structural wood for the construction of various buildings including house poles, boats, tobacco warehouse frames, bridges, waterways, musical instruments, furniture, household appliances and crafts, laminate boards, pulp, chopsticks, toothpicks and etc.
