Standard Beams vs. Wide Flange Beams
Standard Beams and Wide Flange Beams are both used in construction, but they differ in shape, strength, and application.
What Is a Standard Beam?
Standard Beams (often designated with an S shape) feature tapered flanges, meaning the flanges become thinner toward the edges. This gives the beam a narrower profile that has been used in bridges, buildings, and other structures for many decades.
While they are still used today, Standard Beams are less common than they once were because newer beam designs offer improved structural performance.
What Is a Wide Flange Beam?
Wide Flange Beams (designated with a W shape) have wider flanges with nearly parallel inner and outer surfaces. This design allows the beam to distribute loads more efficiently and provide greater resistance to bending.Their increased strength and stability have made Wide Flange Beams the standard choice for most modern structural steel applications.
Key Differences
The primary difference between the two beam types is the shape of the flanges.
- Standard Beams: Tapered flanges with a narrower profile.
- Wide Flange Beams: Wider, nearly parallel flanges that provide greater strength and improved load distribution.
Because of their geometry, Wide Flange Beams typically offer better structural performance for modern construction projects.
Which Beam Should You Choose?
For most new buildings and structural projects, Wide Flange Beams are the preferred option because they offer greater strength, improved load distribution, and increased bending resistance. Standard Beams, however, are still used in certain applications where their specific dimensions, compatibility with existing structures, or design requirements make them the better choice.
Understanding the differences between these beam types can help ensure you select the right steel beam for your project's structural requirements.
