Thanks to its distinctive composition, bamboo stands out for its inherent strength...

In contrast to wood, bamboo lacks rays or knots, providing resilience across the entire length of each stalk.

Bamboo's sectional anatomy, both at a macro scale as a cane and on a microscopic fiber level, bolsters its structural integrity.

The elevated silica content in bamboo fibers renders it impervious to termite digestion.

Bamboo possesses chemical extractives distinct from hardwood, making it exceptionally well-suited for adhesive applications.

In structural engineering assessments, bamboo has demonstrated...

Greater tensile strength compared to numerous steel alloys.

Superior compressive strength when compared to various concrete mixtures.

An exceptional strength-to-weight ratio outperforming even graphite.
