...When our founder, Dr. Liangbing Hu, published his groundbreaking SUPERWOOD process in the prestigious journal Nature in 2018, it marked the beginning of the next major leap forward in the fundamental materials that humanity builds with, a marriage of nature and technology that rises to the needs of today and tomorrow.
Today, after seven years of intense development work, substantial investment, and over 140 patents, SUPERWOOD is ready to reshape how we build our world. This isn't just innovation—it's transformation.

Stronger Than Steel, Able to Stop a Speeding Bullet—It’s Super Wood!
Simple processes can make wood tough, impact-resistant—or even transparent
...Hu and his colleagues say they have come up with a better way to densify wood, which theyreport in the February 7 Nature. Their simple, two-step process starts with boiling wood in a solution of sodium hydroxide (NaOH) and sodium sulfite (Na2SO3), a chemical treatment similar to the first step in creating the wood pulp used to make paper. This partially removes lignin and hemicellulose (natural polymers that help stiffen a plant’s cell walls)—but it largely leaves the wood’s cellulose (another natural polymer) intact, Hu says...
The results are impressive. The team’s compressed wood is three times as dense as the untreated substance, Hu says, adding that its resistance to being ripped apart is increased more than 10-fold. It also can become about 50 times more resistant to compression and almost 20 times as stiff. The densified wood is also substantially harder, more scratch-resistant and more impact-resistant. It can be molded into almost any shape. Perhaps most importantly, the densified wood is also moisture-resistant: In lab tests, compressed samples exposed to extreme humidity for more than five days swelled less than 10 percent—and in subsequent tests, Hu says, a simple coat of paint eliminated that swelling entirely.
