Gerdau (Long Steel North America) – United States

Developed by Gerdau, the five-span standardized rural bridges comply with ABNT NBR 16694 : 2020 and
are tailored for low-traffic rural roads, prioritizing safety, durability, and low maintenance.
The composite system integrates rolled steel beams with precast reinforced concrete slabs, eliminating the need for formwork and ensuring efficient, high-quality construction.
Designed for higher TB-450 live loads and supported by ready-to-use plans and fast assembly, the system enables quick deployment in disaster zones.
