That depends on how heavy it is.

Steel beams are measured by height and width and weight-per-length

As an example A beam you describe as measured in the UK could be 200mm X 100mm X 30kg/m

12 feet is approx 4m so total beam weight 120kg.

This is just an example and it all depends on the unit weight. If you measure the thickness of the steel then look up steel tables online you should get a pretty good idea.
