How heavy is a steel girder?

The dimensions and specifications of a steel girder can affect its weight. However, a steel girder typically weighs between 10 and 20 pounds per foot. As a result, the typical 20-foot steel girder might weigh between 200 and 400 pounds. It's important to remember that heavier, more specialized girders may be used. The specific engineering specifications or a structural engineer should be consulted for precise measurements.
