Mild Steel

mild steel products
Mild steel is a widely used material known for its exceptional strength, affordability, and versatility. It has a low carbon content, making it more ductile and easy to work with compared to other types of steel. Due to its high tensile strength, excellent weldability, and superior machinability, mild steel is ideal for structural and industrial applications. It is also highly durable and impact-resistant, making it a preferred choice for heavy-duty engineering and fabrication projects. Additionally, mild steel can be easily coated or galvanized for enhanced corrosion resistance, further increasing its lifespan in harsh environments.
