I Beam Steel Weight Calculator – Free Tool

What is I beam?

I-beams, also referred to as universal beams, are long steel beams with an I-shaped cross-section. They come in two varieties: ordinary I-beams and light I-beams. These beams have an I-shaped cross-section and are used as structural elements in construction.

Types of I beam

I-beams are primarily divided into three categories: ordinary I-beams, light I-beams, and wide flange I-beams.

Classification of I-beams is based on the height ratio of the flange to the web, resulting in four categories: wide, medium, narrow, and wide flange I-beams.

The specifications of ordinary and light I-beams range from 10 to 60 centimeters in height.

Light I-beams have a narrow flange and thin web, making them lighter in weight compared to other I-beams of the same height.

Wide flange I-beams, also known as H-beams, are characterized by two parallel legs without any incline within the legs. They are considered an economical form of section steel and are produced using a four-high universal mill, hence the name “universal I-beam.

National standards have been established for ordinary and light I-beams.

I Beam Weight Calculator

According to the dimensional, shape, weight, and allowable deviation specifications outlined in GB/T 706-2008 for hot-rolled section steel, the typical length of hot-rolled I-beams ranges from 5 to 19 meters.

In the market, I-beams are usually delivered based on either actual weight or theoretical weight. The deviation between the theoretical weight and actual weight of an I-beam must not exceed a range of -5% to +3%.

An I-beam weight calculator can be used to determine the weight of an I-beam.
