With galvanized steel, you can do more with less. Because of the high strength-to-weight ratio of steel, bridge elements or sign structures are less taxing on the support structure than significantly heavier materials, such as concrete. According to the World Steel Association, the strength-to-weight ratio minimizes substructure costs and can also save money on transportation and handling. Additionally, utilizing less material, one ton of steel can do the same as eight tons of concrete, positively contributes to sustainable development as well.
This benefit is particularly important for bridges spanning large bodies of water, wetlands, or environmentally protected areas, which may require cost-effective long span bridge elements to reach across the long distances in a weight-efficient manner. The ability to use long-span beams minimizes the necessary supports and reduces overall stress to the supporting structure. With galvanized steel you can do more with less, keeping bridge design as simple and strong as possible.
The reduced weight of the overall bridge structure will allow for lighter foundations, which can be particularly helpful in areas with poor ground conditions. Because the foundation transfers and distributes the weight of the bridge from the structure to the ground, a lighter foundation means the surrounding soil will not have to need as much reinforcement to support the weight.
Reducing the weight of a bridge or other transportation structure in total translates to cost savings throughout the process. One of the biggest advantages of steel is weight savings, which mean lower erection costs. The lighter weight of the pieces means they will require lighter, less costly handling equipment during construction.
