> Ultimately, InventWood is planning to use wood chips to create structural beams of any dimension that won’t need finishing. “Imagine your I-beams look like this,” Lau said, holding up a sample of Superwood.<p>I have several exposed PSL beams and posts in my house that cross spans that are too long (~20 ft carrying an upper floor) for dimensional lumber. Because they are stained, most people who are not in construction think it's some kind of exotic hardwood due to the complex patterns made by the wood strands, and don't believe when I tell them it's just woodchips glued and compressed.
