For Teragren products, we specify only Teragren Optimum 5.5 Moso bamboo grown in the Zhejiang province of China. There are more than 1,500 species of bamboo and Moso (Phyllostachys pubescens) is among the hardest, with dense fibers that make for strong timber and beautiful, durable bamboo flooring, panels and veneer. Bamboo has greater compressive strength than concrete and about the same strength-to-weight ratio as steel in tension. But it doesn’t start out that way. To achieve the characteristics valued in construction material, it must be harvested at the right time, between 5-1/2 and 6 years.
Bamboo is a natural product and it will vary from texture, graining, knots, imperfections, and character. Since this is a natural aspect of bamboo, it will create significant variation from plank to plank.
