A36 Steel Standard I-Beam - 4" x 7.7 lbs/ft
This 4" x 7.7 lbs/ft Standard I-Beam is a versatile structural shape made from hot rolled A36 carbon steel. It meets ASTM A36 standards, ensuring a minimum yield strength of 36,000 PSI and excellent weldability, making it ideal for general construction and industrial fabrication. In stock Los Angeles.
- A36 Steel Construction
- ASTM A36 Certified
- 58,000 - 80,000 PSI Tensile Strength
- Excellent Weldability
Hot Rolled Standard I-Beams, also known as S-Beams, are a fundamental component in structural applications. Manufactured to ASTM A36 specifications, this carbon steel grade provides a guaranteed minimum yield strength and excellent formability. The hot rolling process results in a rougher, scaly surface finish but imparts toughness and ductility, making the material easy to weld and fabricate for structural assemblies where strength and reliability are critical.
As a large structural shape, the 4" height is engineered for significant load-bearing applications. It is commonly used for heavy structural framing in commercial buildings, industrial equipment bases that require rigidity and vibration damping, support members for mezzanines, and main rails for trailer and truck bed frames where durability is essential.

Target Users
Structural engineers, general contractors, and heavy equipment fabricators rely on A36 I-Beams for predictable strength and weldability in demanding projects throughout the Los Angeles area.
Finish Options
This product comes standard with a hot rolled mill finish, characterized by a dark, scaly surface. This scale should be removed by grinding or abrasive blasting before coating. For corrosion protection, A36 steel can be primed, painted, or hot-dip galvanized. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Standard I-Beams are designated by their height (A - the distance from the outer face of one flange to the outer face of the other) and their weight in pounds per foot.
Example: To order this I-Beam, specify "A36 Standard I-Beam, 4" x 7.7 lbs/ft".
