There is a new material touting itself as a structural element in the construction industry: bamboo. It has been used for years in Asian countries, and is now making its way to the western world. In fact, it has been certified by the ICC Evaluation Service to be a legitimate structural element.
Bamboo can be used in wall, roof, and floor trusses, or as individual studs. The poles generally range in size from 2 ¾” to 3 ¼” in diameter and 10 to 14 feet long, so they will easily fit into standard western construction. According to the ICC report, they can be used in Type V non-fire-resistance rated residential and commercial construction. In commercial construction use is limited to one story and a maximum floor area of 2000 square feet.
Bamboo makes an excellent substitute for traditional wood framing because of its rapid growth cycle. The largest species, timber bamboo, grows to a whopping 120 feet with a 13 inch diameter in just three years. The stalks can be cut, then left to grow again without replanting. Growing bamboo is good for the soil as well, as it deposits minerals into the ground, and serves to prevent erosion.
The down side of this new product is the cost of transportation. Currently the only bamboo certified for structural use comes from Vietnam and must be treated with borate. Bamboo can be grown in almost any climate, so costs could be reduced as more is grown in the U.S. Locally grown bamboo would also help sales of other bamboo products such as wood flooring and veneer.

Thanks for writing this on the amazing properties of bamboo. Bamboo is one of the fastest growing renewable resources being used for a whole host of products in the green building industry and beyond. My firm EcoLogic Products LLC is utilizing reclaimed bamboo and earth-based resins for use in our sustainable tableware line.
Here’s some more info on Bamboo:
An enduring, fast growing and truly renewable resource, it needs no replanting.
A high-yielding, viable replacement for wood and petroleum based products.
Important economic and ecological benefits including soil and water conservation, jobs, numerous product applications and food- more then 1000 documented uses.
Amazingly short growth cycle, it can be harvested in 3-5 years versus 15-20, typical for many hardwoods.
The fastest growing plant on the planet, some species can grow up to 1 meter or 3 feet per day.
A critical element in the balance of oxygen and carbon dioxide in the atmosphere.
A renewable alternative resource for agro-forestry production.
Bamboo shoots provide a nutritional source of food which can be made into bread, cakes scones and cookies.
Environmentally friendly reduction of pressure on forests through wood substitution.
Products can be made in rural environments, reducing industrial and urbanization impacts.
Bamboo is durable, sturdy and strong – harder than Red Oak and Maple.

Thank you so much
GORGEOUS, BUT BEWARE OF BUGS!!
In 2003, I built a 12 X 24 patio cover out of structural bamboo. I purchased it all from a dealer in Benicia CA who imported it direct from China. The larger ones were 5-6 inches in diameter & ranged in length from 10 to 15 feet, and we used these for the major structural elements, including posts & beams. We also bought some smaller pieces, about 3-5 inches in diameter, to frame the roof & make railings. It came out gorgeous!! Everyone who saw it loved it! And it’s held up quite well, and after 9 years is still structurally very sound. However, about 4 years after we built it, I began to notice small piles of fine sawdust around the bases of the posts. Closer examination revealed tiny bore holes in the bamboo where it was coming from. I had it professionally inspected & it was found that these are powder post beetles & they are incredibly tough & hard to kill. I found a dead one & sent it to the entomology dept at a local college. They determined that it came direct from Asia & that their eggs can live for years before hatching. It came over in the bamboo from China!! I had the entire structure tented & professionally fumigated. They told me it takes 10 times as much poison gas to kill powder post beetles as it does to kill termites. At first I was optimistic. No problems… for about 2 years. Then the piles of sawdust began showing up here & there again. This time I got bug spray & just saturated the areas in question. It seemed to help for awhile, and some of them haven’t come back yet. But in a few areas they have come back, stronger than ever. A small tiki hut made of the same stuff is so bad now that it needs to be torn out entirely. I want to sell my home in the future, and now I’m considering tearing out my beautiful, unique patio cover just because a new buyer, and his termite inspector will see those old bore holes, and ethically, I must disclose the past problems. This would probably kill most sales out there. So, my advice is this: Bamboo is great, and looks fantastic. Just make sure it’s been kiln-dried or in some other way treated so that there can not possibly by any infestation. And bear in mind that most of the stuff coming out of Asia has little or no guarantee. It’s all about low prices. Beware.
Thanks for ending this information. I shall post this on GBE so more people are aware of potential bug problems!

We live on a rural property site that would benefit from growing structural bamboo. Where can we obtain seeds? Due to flash flooding, this would be valuable in erosion mitigation.
