This research evaluated the effect of strand pretreatment and strand mixture ratio on the properties of Dual-Species Bamboo Oriented Strand Board (DS-BOSB) from andong and tali bamboo. Andong and tali bamboo strands were steamed at 126 °C for 1 hour under 0.14 MPa pressure and followed by rinsing by 1% NaOH solution. The two types of strands were then mixed by the ratio of 100:0, 75:25, 50:50, 25:75, and 0:100 for andong and tali strand respectively. Three layered DS-BOSB was made with 0.7 g/cm3 target density and 8% phenol formaldehyde adhesive content. The shelling ratio of boards was 25:50:25 with the size of (30x30x0.9) cm3. The measurement of physical and mechanical properties for DS-BOSB evaluation referred to the JIS A 5908 (2003) standard and the results were compared with the CSA 0437.0 (Grade O-1) standard. The results showed that the steam-treated followed by 1% NaOH rinse on the strand increased the dimensional stability and mechanical strength (internal bond) of DS-BOSB. The higher ratio of tali bamboo improved the dimensional stability and internal bonding of DS-BOSB. The optimal mixture ratio to produce OSB from andong and tali bamboo were 50:50. All OSBs meet CSA 0437.0 (Grade O-1) standard.
