Abstract: A new testing method for the transverse section density of rattan materials was studied by taking three commercial rattan species as experimental materials to compare the density difference in the transverse section. The results showed that the density of ‘Nuo’ rattan was comparatively uniform with high transverse section density, which indicated this species was good raw material for superior furniture making. The quality of ‘Dabai’ rattan ranked the second. The transverse section density of ‘Kongxin’ rattan varied greatly, only the outer part of the rattan could be used for furniture making while the inner part was not valuable. It was feasible and practical to measure the transverse section density of the rattan materials by applying the profile density analysis apparatus, which could provide the processing and utilization of the rattan materials with natural properties.
