Mild Steel Square Bars


Mild steel square bar is a low carbon steel bar that has the cross-section of a square. Mild steel square bars are usually hot-rolled and are ideal for various applications like structural, general fabrication, manufacturing and even industrial maintenance repairs. With its high strength and versatility, mild steel square bars can be drilled, welded, machined and cut to suit a wide range of general engineering and manufacturing applications.


Uses of mild steel square bar include structural and construction applications, manufacturing, transportation equipment, general fabrication, industrial maintenance, agricultural implements and decorative applications.


Two of the common grades of mild steel square bars are EN10025 S275 and BS4360 Grade 43A. EN10025 S275 is a popular mild steel grade suitable for various general engineering and structural applications. As a low carbon steel specifications, EN10025 S275 provides low strength with good machinability and can be easily welded. Mild steel grade S275 is used widely in the construction, industrial maintenance and manufacturing industries.

Mild steel grade BS4360 Grade 43A is another widely used carbon structural steels, which is suitable for a large number of engineering applications. It is cheaper than most other mild steel grades, which makes it suitable for different applications such as building and machinery constructions that do not require wear-resistance and high strength.
