ASTM A36 C Channel Steel
Within the first stage of project design and material selection, choosing ASTM A36 C Channel Steel ensures a reliable balance between strength, affordability, and availability.
Manufactured in accordance with ASTM A36/A36M standards, this steel channel is suitable for load-bearing structures, equipment frames, and infrastructure systems across multiple industries.
ASTM A36/A36M Standard Explanation for C Channel Steel
The ASTM A36/A36M standard is the foundational U.S. specification for carbon structural steel. It covers a wide range of product forms, including plates, bars, and structural shapes such as angles, channels, I-beams, and H-beams.
This standard defines:
- Chemical composition limits
- Mechanical property requirements
- Dimensional tolerances
- Manufacturing and quality control procedures
ASTM A36 is recognized globally as an entry-level structural steel grade, particularly dominant in the North American market.
ASTM A36 C Channel Steel Grade Meaning and Yield Strength
The designation ASTM A36 has a clear technical meaning:
"A" represents ferrous (iron-based) material
"36" indicates a minimum yield strength of 36 ksi, equivalent to ≥250 MPa

ASTM A36 C Channel Steel
This yield strength value defines ASTM A36 as a general-purpose carbon structural steel. Its core value lies in its cost efficiency, stable supply, and excellent overall fabrication performance, making it suitable for both small-scale and large-scale projects.
ASTM A36 C Channel Steel Chemical Composition and Mechanical Properties
ASTM A36 C Channel Steel belongs to the carbon steel category and contains a balanced combination of alloying elements to ensure consistent performance.
Mechanical Properties of ASTM A36 C Channel Steel
| Property | Approximate Value |
|---|---|
| Yield Strength | ≥250 MPa |
| Tensile Strength | 400–550 MPa |
| Minimum Elongation | 20% |
| Density | 7.85 g/cm³ |
Thanks to this combination of strength and ductility, ASTM A36 C Channel Steel provides an excellent strength-to-weight ratio, making it ideal for lightweight yet durable metal structures.
Standard Dimensions of ASTM A36 C Channel Steel
ASTM A36 C Channel Steel is manufactured in a wide range of sizes to meet different load and design requirements.

What is A36 structural channel?
A36 steel channels are a commonly used material in construction and building projects. This low-carbon steel is not heat treated, meaning that its strength and durability don't come from hardening. It is most commonly used when great load-bearing capacity or support is required, such as beams and girders.
What does A36 stand for?
A36 is designated by its mechanical properties instead of its chemical properties. In the American Society for Testing Materials (ASTM) system, the A stands for ferrous metal, while the 36 refers to its minimum yield strength of 36,000 PSI.
Why is it called A36 steel?
It's one of the most commonly used steel grades for structural applications in the United States. The number "36" refers to its minimum yield strength (36,000 psi).
What is A36 material equivalent to?
The ASTM A36 plate is equivalent to grades like ASTM A283C, JIS G3101 SS400, JIS G3106 SM400A, EN10025-2 S235JR, DIN17100 ST37-2, and FE360B.
Is A36 steel still used?
A36 steel is one of the most used structural steels in North America.
Can A36 steel be hardened?
A36 can be flame hardened but has not got a high enough carbon content for the usual quenching and tempering. 1018 but also A36 can be carburized, which gives either steel grade a harder surface.
