InventWood's Superwood represents a breakthrough material that transforms ordinary wood into a substance stronger than steel through molecular restructuring and densification[^1]. The company is launching a 90,000-square-foot manufacturing facility in Frederick, Maryland in Q3 2025 to begin commercial production[^7].

Key features of Superwood:

  • 50% more tensile strength than steel with 10x better strength-to-weight ratio[^9]
  • Fire-resistant, rot-resistant, and pest-resistant while maintaining wood's natural appearance[^7]
  • Created through a two-step process involving chemical treatment and hot-pressing[^8]
  • Can be produced in hours rather than weeks using "food industry" chemicals[^9]

Environmental Impact:

  • Could replace up to 80% of global steel and concrete use[^5]
  • Potential to reduce carbon emissions by 37.2 gigatons over 30 years[^5]
  • Trees act as carbon stores: steel produces 1.85 kg CO2 per kilogram, while wood removes 1.8 kg CO2[^5]

Business Development:

  • Secured $15 million in Series A funding in 2025[^7]
  • Total capital raised exceeds $50 million[^7]
  • Formed partnership with Intectural for North American distribution[^7]
  • Initial products will focus on building facades before expanding to structural applications[^9]

How do you join or cut these pieces of wood if they are harder than steel? Can’t drive ordinary nails or screws or saws through steel.

I think that to work with it isn't so different as working with metal or even wood. Even if it is harder than normal steel, it won't be a problem to drill, or cut it-

There would also be the possibility of forming the wood into a workable shape beforehand. IIRC it doesn't shrink that much, just compresses, so it's possible to have holes and angles where you need them; joinerery would be an issue though.
