How to Read Steel Beam Sizes?

The number that follows the letter is called the section number and is the “height” of the i. The second number is the pounds per lineal foot, or how much each foot of the beam weighs. Sometimes, there will be a third number that represents the length of the beam (in feet).

How to Read Steel Beam Sizes?

Steel beams are a vital component of any construction project. They are used to hold up the structure of a building and provide additional support for weight–bearing walls and floors.

Reading steel beam sizes is important for any construction project, as it helps ensure that the right size beam is selected for the job.

This article will explain how to read steel beam sizes and provide some helpful tips for selecting the right beam size for your project.

The first step in reading steel beam sizes is to identify the type of beam. There are several different types of steel beams, including I–beams, H–beams, U–beams, and L–beams.

Each type of beam is designed for different applications, so it is important to choose the right type of beam for your project. Once you have identified the type of beam, you can begin to read the size.

Steel beam sizes are typically measured in millimeters (mm), which is the unit of measurement for length. The size is usually indicated on the beam itself and is typically written with the letter “W” followed by two numbers, such as W50x4.

The first number indicates the beam’s width, while the second number indicates the beam’s height.
