Steel Beam Sizes

Having a good resource for I beam sizes is very important when designing structures. As a structural engineer, it is important for us to identify sections that are not only safe, but also cost-effective. With the steel beams size chart below, SkyCiv aims to have a free resource that can be accessed anytime via the browser. The below steel beam size chart, will help structural engineers find the appropriate size and shape that you need for your project. These properties are important in the verification of the section's strength capacity, which is the very definition of structural design.

Using the Table

The Steel Beam Sizes Chart is an interactive table that lists the dimensional and geometric properties of a section. These properties can help engineers find the desired steel section they are looking for. Simply select your unit system, library before selecting a shape to display that shape's beam dimensions. The library contains sections from the Australia, United States, Canada, United Kingdom, and Europe. The software pulls the beam dimensions directly from Structural 3D's database, which is the main 3D structural analysis software of the SkyCiv platform that is also available for use from within a web browser. These information usually require the user to keep a manual or steel beam charts on-hand, which can be an inconvenience, that is to say, if the user has a copy. While there is a monetary cost to acquiring a steel manual, we must highlight once more that SkyCiv's reference table is easily accessible here at no cost.

Some of the dimensions this tool can display:
  • I-Beam Sizes
  • S-Beam Sizes
  • Square hollow/HSS Sizes
  • Round HSS Sizes
  • Wide Flange Beam Sizes
  • T Beam Sizes
  • Channels Sizes
  • Angles Sizes
  • Imperial and Metric Beam Sizes

Steel Section Sizes

The above steel section sizes should give the user the ability to easily access the member properties and dimensions of commonly used sections in various libraries around the world. We hope engineers find a reference for these steel beam sizes and dimensions valuable to their work flow. Again, there are currently steel sizes and dimensions for Australian, US, UK, European and Canadian shapes. If a particular library that you use is not available, you can contact us here. We are open to improving and expanding our database. Another great aspect of this tool is that it can convert the beam dimensions from metric to imperial and vice versa. This saves the engineer time, if working across unit systems, and reduces the risk of an error in the calculations.

Section Properties

The section properties displayed by the above table includinig cross sectional area (A), ploar moment of inertia (J), moment of area (Iz, Iy), section modulus and warping constant (Iw). These results are extremely important when considering structural steel for your beam and column designs. They are the properties that control the amount and type of force a steel member can take.

Need to Design a Structure?

Here at SkyCiv, we have a range of software (free and paid) that allow engineers to model and design their structures. Our free beam calculator is an easy to use calculator to help analyse cantilever and simply-supported beams. You can also check out our truss calculator for quick analysis of 2D trusses. For small 2D frames, you can use our free structural frame calculator. For typical shapes of non-standard steel sizes, the free moment of inertia calculator is a good resource to obtaining their geometric and section properties.



If you are an engineering professional, you might benefit more by using our could based 3D Structural Analysis Software. This software includes integrated design modules such as AISC, ACI, AS, Eurocode and CSA. Check out our professional packages here:
