Square iron is a solid iron and steel product with a square cross-section. It is widely used in construction, manufacturing, agriculture and many other fields. They are irons with a completely filled square cross-section. They are preferred in applications requiring high strength and durability. S235JR ( ST37 ), S275JR ( ST44 ), S355JR ( ST52 ) Quality, hot rolled square shaped metal materials with a thickness between 8.00 mm and 250.00 mm. The standard is 6 MT. Special size production can also be made according to the desired size according to the project situation.

Features of Square Iron:
Material: They are usually made of carbon steel.
Dimensions: The dimensions of square irons are determined by the edge length and wall thickness. They can be produced in different sizes and thicknesses.
Surface: Their surfaces are usually smooth. It can be optionally galvanized or different surface treatments can be applied.

 Advantages of the Square Iron:
 High Strength: It has high tensile and yield strength. This feature increases the capacity to carry heavy loads.

Easy Processability: It can be easily shaped by processes such as cutting, drilling, welding and bending.
Diversity: Available in different sizes and thicknesses to suit a variety of applications.
Economical: It is generally more economical than other structural steel profiles.
