One of our goals is to reduce the amount of carbon that the construction industry produces. DonoBeam‘s innovative design reduces the amount of steel needed, with high bending resistance and optimal torsional stiffness. Research by Monash University shows DonoBeam reduces carbon emissions by up to 40% compared to conventional systems, decreasing the carbon footprint from your project materials, freight, and on-site construction.
