CROSS-HATCHED BAMBOO STRAND LUMBER
20210387376 · 2021-12-16 ·

System and method for manufacturing bamboo dimensional lumber having cross-hatched fiber layers. The method involves splitting bamboo poles into smaller slats, which are then and crushed into fibers. These fibers are covered with glue, and laid in alternating perpendicular layers. The combined layers are hot pressed to form a rough lumber board composed of cross-hatched bamboo fiber layers. The board is then cut to any desired dimensions for lumber.
