The angle steel bar, namely the angle iron, is a kind of long strip-shaped steel products with the right-angled cross section. It has the type with two equal sides and the type with two unequal sides. The product with two equal vertical sides is the equal angle iron. The one with two unequal vertical sides is the unequal type angle iron. The specification of the product is expressed by width × width ×thickness with the unit of millimeter. The specification of the equal product can also be measured by using the unit of centimeter.
A. Prime Equal Angle Steel Bar
The angle iron can compose a variety of mechanical components according to the needs of the structure. It can also play the function of being steel fastener among the construction members. The angle iron is widely applied in various construction structures and engineering structures involving the large structure of factory building, bridge, automobile, etc. It is also applicable for the construction truss, iron tower, headframe, etc.
The hot rolled equal angle steel bar ranges from 2# to 20# in specification. If the side width of the product is larger than 150mm, we rank the product into the large type category. Accordingly, the medium type category refers to the product with the width of one side ranging from 50 to 150mm. Then, the product with the side width less than 50mm belongs to the small type category.

B. Prime Unequal Angle Steel Bar
This type of product has two sides with different widths. Its specification is shown by long side width × short side width × thickness with the unit of millimeter. The hot rolled unequal type product is manufactured with the specification ranging from 2.5/1.6# to 20/12.6#. According to the size, it also falls into the large type, medium type and small type. The large type mainly works for the large structures such as factory building, bridge, automobile, etc. The medium type is basically suitable for construction structure, truss, steel tower, support, etc. The small type is taken for use as structural part.
