Why Are I-Beams Ideal For Construction Purposes?

September 24, 2021

The I-beam is one of the standard structural steel beams that construction companies use as building backbones. They're a huge investment because they have exceptional strength and load-bearing capabilities. You can learn more about I-beams in this post.

I-Beam: Materials Used

I-beams require the best materials available because they are required to have a long-term lifespan and performance. Thus, structural steel beam fabricators always use the following materials in every construction project.


  • Aluminum: Lightweight and durable I-beams that can bend and deform in the hands of a capable fabricator. Aluminum I-beams see extensive use in aircraft manufacturing.
  • Steel: Steel is a construction staple and a critical part of structural engineering and is used in constructing buildings, frames, or bridges.
  • Carbon: Low metal alloys are a crucial part of construction projects. These are much more affordable than steel but deliver almost the same level of strength and load-bearing capabilities.

I-Beam: Standard Properties

Fabricators and engineers consider the following properties in sourcing raw materials, designing, and implementing I-beams:


  • Deflection: Refers to the beam's deformation when handling load-bearing stress.
  • Vibration: Density and stiffness that reduces building vibrations and unwanted noise.
  • Bend: All I-beams must maintain their properties with minimal bending in managing yield stress.
  • Buckling: I-beams have flanges that prevent buckling sideways. 
  • Tension: An I-beam must sustain weight and never buckle, ripple, or fail under any tension.

I-Beam Usage

I-beams are a coveted resource to every builder. Here are the typical applications of a high-quality I-beam used by structural steel beams fabricators:


  • Construction: Buildings always need I-beams that will never fail. Thus, construction companies will tend to buy I-beams in bulk as they are often used as critical support trusses.
  • Ship-Making: Ships use high-quality aluminum I-beams that can bend but stay afloat and buoyant. 
  • Public Structures: Bridges, lamp posts, lawn furniture, and other public structures use I-beams extensively.
