A36 Hot Rolled Standard I-Beam - 8" x 18.4 lb/ft
This 8" x 18.4 lb/ft structural I-beam is manufactured from hot rolled A36 steel, providing a guaranteed minimum yield strength of 36,000 PSI. Its S-beam shape is highly efficient for resisting bending loads, making it a reliable choice for heavy structural applications. In stock Los Angeles.
- A36 Carbon Steel Construction
- ASTM A36 Certified
- 36,000 PSI Yield Strength
- Excellent Weldability and Formability
Hot rolled A36 I-beams, also known as Standard American Beams or S-beams, are a foundational component in structural steel fabrication. Produced to ASTM A36 specifications, this grade offers excellent strength, ductility, and superior weldability, allowing for easy on-site modifications. The characteristic 'I' shape, with a central web and parallel flanges, provides an efficient geometry for managing bending and shear stresses in load-bearing applications.
As a large structural profile, this 8-inch I-beam is engineered for heavy-duty use. It is commonly specified for primary building frames, support girders for mezzanines and bridges, crane runway beams, and robust bases for industrial machinery where strength and rigidity are critical design requirements.

Applications
- Construction: Main building frames and roof trusses - for its high load-bearing capacity.
- Infrastructure: Bridge support members and short-span girders - due to its predictable strength.
- Industrial Equipment: Heavy machinery bases and support frames - for excellent vibration damping and rigidity.
- Material Handling: Crane runway beams and hoist supports - for safely resisting dynamic loads.
Target Users
Structural fabricators, general contractors, and heavy equipment manufacturers rely on A36 I-Beams for predictable performance and ease of fabrication in projects throughout the Los Angeles area.
Finish Options
This product comes standard with a hot rolled mill finish, which includes a layer of dark mill scale. This surface should be removed by grinding or abrasive blasting before painting or coating. For corrosion protection, A36 steel can be primed, painted, or hot-dip galvanized. Contact our Los Angeles sales team for custom coating inquiries.
How to Measure
An I-Beam is identified by its Height (the tallest dimension of the web) and its Weight per Foot. Other key dimensions are Flange Width and Web Thickness.
Example: To order this I-Beam, specify "8 inch by 18.4 pound I-Beam" or use the standard designation "S8x18.4".
