General Structural Steel Plate refers to low‑carbon, mild structural steel widely used in construction, machinery, and general engineering applications.
These steels offer:
Good weldability
Excellent formability
Stable mechanical properties
Cost‑effective performance
Wide availability in global markets
This category includes the most commonly used structural steel grades worldwide.
🟧 Key Features
Mild carbon content for easy welding and forming
Suitable for bending, cutting, drilling, and fabrication
Good strength‑to‑cost ratio
Ideal for general structural applications
Available in a wide range of thicknesses and widths
