Is the airbag bridge better or the steel plate?

Steel plate. The airbag bridge is light in weight, but it also has the problems of more complicated structure and higher maintenance and replacement cost than the steel plate bridge, so it is not suitable for transporting heavier goods. Compared with airbag bridge, the most obvious advantages of steel bridge are simple structure, low construction and maintenance cost, stronger stiffness and higher bearing capacity. So, to sum up. Steel bridges are better.
