Bright Steel Square Bars

Bright Steel Square Bars


Bright steel square bars are steel bars with a polished surface finish and a square cross-section. Produced through cold drawing or rolling processes to achieve a smooth, reflective surface finish, they come in various sizes and are made from carbon steel, alloy steel, or stainless steel. Used in construction and manufacturing, these bars are ideal for precision components like keys and fasteners. The polished surface finish also makes them suitable for applications where an aesthetically pleasing appearance is desired.


Uses of bright steel square bars include machine components such as gears, bushings, and couplings, construction fasteners, support brackets, tools and dies, automotive components, agricultural equipment, oil and gas, marine, household appliances, furniture, machinery, railways, bolts, pins, shafts and precision engineering.


One of the common bright mild steel grades used for bright steel square bars is JIS G3101 SS400. SS400 is a low carbon mild steel grade with good weldability and formability. SS400 bright steel square bar is used in many industries like automotive, agriculture, marine and construction. SS400 cold drawn steel square bar has better dimensional tolerance and smooth surface to be used for specific machining operations. SS400 is a widely used and versatile structural steel due to its combination of strength, formability, and ease of fabrication. Common applications include bridges, buildings, machinery parts, and general structural purposes.
