A36 Hot Rolled Steel Angle - 7" x 4" x 1/2"
A36 hot rolled steel angle measuring 7" x 4" with a 1/2" thickness, supplied in 20-foot lengths. This heavy-duty structural angle conforms to ASTM A36 and provides a minimum yield strength of 36,000 PSI with excellent weldability, making it ideal for large-scale fabrication. In stock Los Angeles.
- A36 Carbon Steel Construction
- ASTM A36 Certified
- 36,000 PSI Yield Strength
- Excellent Weldability
A36 hot rolled steel angle is a low-carbon structural steel produced by forming at high temperatures, resulting in a scaled surface finish and reliable mechanical properties. Conforming to ASTM A36, it combines high strength and excellent weldability at a low cost, making it a foundational material for general construction and industrial fabrication where precise tolerances are not the primary requirement.
As a large structural section, this 7" x 4" x 1/2" angle is specified for heavy-duty applications. Its size provides significant rigidity and load-bearing capacity, making it ideal for building frames, heavy equipment bases, industrial supports, and large-scale structural reinforcement projects requiring maximum strength.

Target Users
Structural engineers, fabricators, and construction contractors rely on A36 angle for its strength and weldability in heavy-duty projects throughout the Los Angeles area.
Finish Options
This product comes standard with a hot rolled mill finish, characterized by a blue-gray, slightly rough surface scale. This scale must be removed by grinding or blasting before painting or coating to ensure proper adhesion. For outdoor use, a protective finish like galvanizing or primer is required. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Steel angle is measured by its two legs (A & B) and its thickness (C). For an unequal leg angle like this one, both leg dimensions are required for identification. Measurements are taken from the outer corner.
Example: To order this angle, specify "A36 Angle, 7 inch by 4 inch by 1/2 inch thick".
