- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
A36 Hot Rolled Steel Angle is produced by forming steel at high temperatures, resulting in a product with slightly rounded corners and a scaly finish. This process makes it cost-effective and easy to work with. Conforming to ASTM A36, it provides a dependable combination of strength, ductility, and outstanding weldability, making it a foundational material for general structural and fabrication projects.
As a large-profile angle, this 4" x 4" size provides substantial rigidity and load-bearing capacity. It is primarily used for heavy structural applications, including building frames, main support members for industrial equipment, trailer frames, and large-scale bracing where maximum strength is essential.

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 before painting or coating. For projects requiring enhanced corrosion resistance, galvanizing or specialized coatings can be applied after proper surface preparation. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Angle is measured by its Leg dimensions (A and B) and its Thickness (C). For an equal leg angle like this one, both leg measurements are the same.
Example: To order this angle, specify "A36 Steel Angle, 4 inch by 4 inch by 3/4 inch thickness".
