    The central "web" of the steel I-beam is often wider than a column web to resist the higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, below a thick layer of concrete and steel reinforcing bars. Another popular alternative is a floor of precast ...
