What Is Structural Steel?
Structural steel—also known as construction steel—is a type of carbon steel designed specifically for load-bearing and engineering applications. It provides high strength, excellent toughness, and reliable weldability, making it essential for buildings, bridges, machinery, industrial plants, and infrastructure projects.
At Huaxiao Metal, we focus on supplying carbon-based structural steel grades, covering common global standards such as ASTM, EN, JIS, and GB. Our products serve engineering contractors, fabricators, EPC companies, steel structure manufacturers, and procurement teams worldwide.
If you need a reliable structural steel supplier with stable pricing and large stock, Huaxiao Metal is ready to support your project.
International Standards & Grades
| Standard | Common Grades | Yield Strength (MPa) | Tensile Strength (MPa) | Applications |
|---|---|---|---|---|
| ASTM | A36, A572 Gr50, A573 | 250–345 | 400–550 | Buildings, bridges, machinery |
| EN 10025 | S235, S275, S355 | 235–355 | 360–630 | Structural components, fabrication |
| JIS G3101 | SS400 | 245 | 400–510 | Construction, welded parts |
| GB/T | Q235, Q345 | 235–345 | 370–570 | Engineering, welded structures |
These grades represent the most widely used structural steels globally and cover the majority of engineering requirements.
Key Mechanical Properties
| Property | Description |
|---|---|
| Yield Strength | Ensures the structure does not deform permanently under load. |
| Tensile Strength | The maximum stress steel can withstand before failure, critical for ultimate load calculations. |
| Ductility | Ability to deform without breaking; important for seismic and impact resistance. |
| Weldability & Workability | Facilitates site cutting, welding, and installation. |
| Toughness | Prevents brittle fracture under dynamic loads and extreme conditions. |
Huaxiao Metal’s steel meets or exceeds international quality standards, ensuring reliable structural performance.
