How much does a standard construction I-beam weigh?

Steel beams come in all sizes and shapes, depending on what they're used for, and there's not really a "standard" size. However, the way they're named conveniently describes their height, in inches, and by weight / per foot. So, a "W18x40" beam is 18" high, and weigh 40 lbs / foot. read more

Shape, height and weight per foot, for instance W8x24, is a wide flanged beam, that is roughly 8″ tall and weighs 24 lbs per foot. If you are researching an in place beam, you can look up the density of steel and utilize your approximate measurements for an approximate cross section, to develop your approximate weight per foot. read more

The weight of a steel beam depends on its volume and the weight density of steel. Volume depends on the dimensions of the beam and determines how much space it occupies. Weight density measures the number of pounds a cubic foot of a substance weighs. For standard construction steel, the weight density is about 490 pounds per cubic foot. read more
