A36 Hot Rolled Standard I-Beam - 3" x 5.7 lbs/ft
This 3" x 5.7 lbs/ft Hot Rolled Standard I-Beam is manufactured from A36 steel, conforming to ASTM A36 standards. It provides a minimum yield strength of 36,000 PSI, excellent weldability, and superior load-bearing capacity for structural applications like frames and equipment bases. In stock Los Angeles.
- A36 Carbon Steel Construction
- ASTM A36 Certified
- 36,000 PSI Minimum Yield Strength
- Excellent Weldability & Formability
Hot rolled I-beams, also known as Standard American Beams or S-beams, are a fundamental component in structural steel projects. Manufactured through a hot rolling process, A36 steel beams have a rougher surface finish but offer excellent formability and ductility. Their geometry consists of a central web connecting two parallel flanges, providing superior load distribution and a guaranteed minimum yield strength of 36,000 PSI.
The 3" height classifies this as a medium-sized beam, ideal for equipment frames, mezzanines, floor joists, and trailer cross-members. Its balance of strength and manageable size makes it a versatile choice for general construction and fabrication projects requiring reliable structural support, where it efficiently resists bending loads and shear forces.

Target Users
Fabricators, construction contractors, and machine builders rely on A36 I-beams for predictable strength and weldability in structural projects throughout the Los Angeles area.
Finish Options
This product comes standard with a hot rolled mill finish, characterized by a rougher, scaled surface. This scale should be removed by grinding or sandblasting before painting or coating. For enhanced corrosion protection in exterior environments, beams can be primed, painted, or galvanized. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
A Standard I-Beam (S-Beam) is measured by its Height (A), Flange Width (B), and Web Thickness (C). The weight per foot (lbs/ft) is also a key identifier.
Example: To order this I-Beam, specify "Standard I-Beam, 3" x 5.7 lbs/ft".
