Compared with wood, bamboo has many advantages: high strength, large tenacity, strong rigidity, tractability, and has better physical mechanical performance. Bamboo�s static bending strength, rigidity, and strength of extension can be up to than twice that of wood. Folding strength and surface degree of bamboo flooring is greater than that of wood flooring.
