Our bronze features a proprietary alloy of copper and zinc for superior strength and ductility, allowing a slim 40mm profile with zero compromises in rigidity and performance over time. The natural rust and corrosion resistance of bronze makes B40 an optimal solution for harsh climes. 

And with aesthetic touches that suggest the classic, towering architectural achievements of the early 20th century, B40 looks equally at home in your mountain retreat or your urban highrise.
