The I Beam Size Chart provides detailed information about different sizes of I beams, commonly used in construction and engineering projects. The chart includes key measurements such as depth, weight per foot, web thickness, flange width, and flange thickness. These dimensions are essential for understanding the structural properties and load-bearing capacities of I beams. By referring to this chart, professionals can make informed decisions regarding the selection of I beams for their specific applications.


What is an I beam and what is its purpose?

An I beam is a structural steel beam with an 'I' shaped cross-section. Its purpose is to provide structural support and distribute the weight of the load evenly.

How is the size of an I beam determined?

The size of an I beam is determined by its dimensions, specifically its height, width, and thickness.

What are some common I beam sizes?

Common I beam sizes include 4 inches, 6 inches, 8 inches, 10 inches, and 12 inches in height. These sizes refer to the height of the beam, not its width or thickness.

How can I choose the right I beam size for my project?

Choosing the right I beam size for your project depends on several factors such as the load requirements, span length, and the type of construction. Consulting a structural engineer or referring to a beam size chart can help determine the appropriate size.

What are some other factors to consider when selecting an I beam size?

In addition to the load requirements and span length, other factors to consider when selecting an I beam size include the material being used, the desired deflection and bending capacity, and any specific building codes or regulations that need to be followed.
