On the ruins of southeastern Brazil, which was just hit hard by landslides, three firefighters struggled to lift the body of a victim from the thick mud. On Tuesday this week, the region was hit by a severe rainstorm. So far, 30 deaths have been confirmed, and another 39 people are still missing. A river in Minas Gerais State burst its banks under the heavy load, and the all-night downpour turned once-familiar streets into roaring brown torrents in an instant. Meteorological data shows that the rainfall in the region this month has set a record high. According to the fire department of Minas Gerais State, 30 people have unfortunately lost their lives in the hardest-hit cities of Juiz de Fora and Ubá, but rescue forces have successfully rescued more than 200 trapped people. Currently, firefighters and search and rescue dogs are racing against time to search for the 39 missing people who have not yet returned home in the devastated ruins.

The catastrophic mudslides and flash floods triggered by extreme rainfall have severely damaged the transportation infrastructure in southeastern Brazil, particularly the river-crossing bridges and mountainous road bridges. A substantial number of bridges have been destroyed, washed away, or temporarily closed due to mudslide deposits and flood scouring, which has completely cut off the lifeline for emergency rescue operations, relief material transportation, and residents’ travel. At this critical juncture, Bailey bridges, featuring rapid assembly, high load-bearing capacity, modular transportability, and adaptability to complex terrain, have become the most urgent emergency equipment for traffic restoration in disaster-stricken areas. Brazil’s bridge design and construction must comply with the technical standards formulated by the Brazilian Association of Technical Standards (ABNT). Among these standards, NBR 8800:2024 (Design of Metal and Composite Structures) serves as the core specification for steel structure bridges, which is closely aligned with the American AISC 360 and European Eurocode 3 systems. This standard imposes specific requirements on the fatigue resistance, seismic performance, and corrosion resistance of Bailey bridges to adapt to Brazil’s local tropical rainy climate and complex geological conditions, especially in disaster-stricken areas prone to mudslides and floods.

China is a global leader in the R&D, design, and manufacturing of Bailey bridges, boasting mature production technologies, complete product specifications, and extensive experience in overseas exports. The following are the top 10 Bailey bridge manufacturers in China recommended for Brazil, all of which are capable of providing products that fully comply with Brazilian NBR standards and possess the technical capability to meet the emergency traffic restoration needs in Brazil’s disaster-stricken areas, including the hardest-hit Juiz de Fora and Ubá in Minas Gerais State.
