Heavy-Duty for Main Roads and Factories
This product has a very strong load structure. The single span of the steel frame bridge is 6 to 36 meters. This size fits medium and large rivers or underpasses. The standard deck width of the product is 3 to 12 meters. This width fits one or two lanes for cars and trucks. The design load meets City-A level or heavy highway level. The earthquake resistance is 6 to 7 degrees. This is fine for normal municipal and field conditions.
