To install Tre-Gai, pre-drill a hole before screwing through the bamboo. Try to screw through the node—the thickest part of the bamboo pole—if you are able.

Can I stain the polyurethane-treated Bamboo Poles?

No, you would need to use natural Tre-Gai bamboo poles and sand them lightly to stain.

Is Tre-Gai Bamboo susceptible to insects?

No, amaZulu only sells pressure-treated re-Gai bamboo

Is the diameter the same width throughout the pole?

Because Tre-Gai bamboo is a natural product, the diameter can vary up to one inch per 10 linear feet.

Tre-Gai Bamboo


Tre-Gai bamboo is a premium choice for large-diameter bamboo poles. It is a rapidly renewable, construction-grade bamboo, which makes it a premium choice for structural purposes. The poles average between 2-3 inches and 3-4 inches in diameter. Lengths of 8 feet, 10 feet, and 12 feet are available. It is often used to build pillars, roofs, flooring and so much more. Its pronounced nodes offer a distinctly rustic look ideal for any setting.


  • Available in 10′ and 12’ lengths and average between 2-3” and 3-4” in diameter.
  • All poles are pressure-treated, to ensure treatment penetrates the entire bamboo wall to protect against the Powder Post Beetle.


  • Each bamboo pole has a wall thickness of 50 to 100 percent that resists splitting.
  • Pronounced and rustic-looking nodes
  • Color varies in shades of tan.
  • Note that all dimensions are approximate.

Additional Benefits:

  • The bamboo poles are sturdy and long-lasting.
  • They create an authentic atmosphere for your installations.
  • Natural coloring also adds to that authenticity.

General Contractor and Architecture Engineering Notes:

Tre-Gai has a more rustic look than other bamboo, as the nodes are more pronounced. Our Tre-Gai bamboo is all-natural, so its colors will vary! This can create a more rustic and tropical look for your upcoming project.
