ASTM A36 Structural Wide Flange H Beam
Within the first stage of structural design, material selection directly impacts fabrication efficiency and overall budget. ASTM A36 Structural Wide Flange H Beam, featuring low carbon content and balanced mechanical strength, is widely chosen for applications where extreme load resistance is not required but ease of welding and forming is essential.
As a direct supplier, we ensure consistent material performance, full Mill Test Certificates, and export-ready packaging.
ASTM A36 Structural Wide Flange H Beam for Construction Applications
ASTM A36 is a standard low-carbon structural steel grade defined by ASTM specifications. Compared with higher-strength structural steels, A36 emphasizes practicality, fabrication convenience, and cost efficiency.
Due to its moderate yield strength and excellent ductility, ASTM A36 Structural Wide Flange H Beam is commonly used in light to medium-duty structures. The material can be easily welded, machined, drilled, and formed without complex heat treatment, making it suitable for mass fabrication and on-site installation.
This balance between strength and workability allows A36 H Beams to be widely accepted in both permanent and temporary structures.
Manufacturing Process & Surface Treatment of A36 H Beams
All ASTM A36 Structural Wide Flange H Beams are produced using hot rolled technology to ensure uniform section geometry and stable mechanical properties.
Production & surface options include:
- Technology: Hot rolled
- Surface condition:
- Black (as rolled)
- Galvanized
- Primed
Surface treatment can be selected according to environmental exposure, corrosion requirements, and project specifications.
Chemical Composition of ASTM A36 Structural Wide Flange H Beam
The chemical composition of ASTM A36 Structural Wide Flange H Beam is strictly controlled to guarantee weldability and consistent mechanical performance.
| Steel Grade | Product Form | Carbon (C), max % | Manganese (Mn), % | Phosphorus (P), max % | Sulfur (S), max % | Silicon (Si), % |
|---|---|---|---|---|---|---|
| A36 | Steel sections | 0.26 | - | 0.04 | 0.05 | ≤ 0.40 |
Note: Copper content can be added when specified in the purchase order to improve atmospheric corrosion resistance.
Mechanical Properties of A36 Structural Wide Flange H Beam
ASTM A36 H Beams provide reliable mechanical performance for structural and fabrication use.
| Steel Grade | Product Form | Tensile Strength | Yield Strength (min) | Elongation (200 mm) | Elongation (50 mm) |
|---|---|---|---|---|---|
| A36 | Steel sections | 400 – 550 MPa | 250 MPa | 20% | 21% |
These properties make A36 H Beams suitable for light-load structural members requiring good ductility and safety margins.

What is A36 grade steel 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.
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.
Is A36 high strength steel?
A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
Does A36 steel rust easily?
The material can be easily machined, making it suitable for manufacturing processes. Corrosion Resistance: While A36 steel has some resistance to corrosion, it is often coated or painted to enhance its durability in harsh environments.
What makes A36 steel so popular?
This steel plate is known for its high strength, formability, and weldability. It's also an excellent magnetic field conductor. Together, these benefits make A36 one of the most-used grades of carbon steel. The American Society for Testing and Materials (ASTM) designated it A36.
Is A36 good for bending?
ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018.
