Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other on both sides. There are equal angle steel and unequal angle steel. The sides of the equiangular steel are equal in width. The angle steel can be composed of various force-receiving members according to the different needs of the structure, and can also be used as a connecting member between the members.

Angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, cable trench supports, power piping, busbar mounting, container racks and warehouses. Shelves, etc.

Angle steel is a carbon structural steel for construction. It is a steel section of simple section, mainly used for the frame of metal components and workshops. Good weldability, plastic deformation properties and certain mechanical strength are required in use. The raw material billet for producing angle steel is a low carbon square billet, and the finished angle steel is delivered in hot rolling, normalizing or hot rolling.

Angle steel inspection method:

1) Appearance quality: The surface quality of angle steel is specified in the standard. Generally, there must be no harmful defects in use, such as delamination, crusting, cracks, etc. The allowable range of angle geometry deviation is also specified in the standard (GB9787-88/GB9788-88), generally including bending, edge width, edge thickness, apex angle, theoretical weight, etc., and specifies that the angle steel must not have significant torsion.

2) Mechanical property test: 1 tensile test method. Commonly used standard inspection methods are GB/T228-87, JISZ2201, JISZ2241, ASTMA370, FOCT1497, BS18, DIN50145, etc.; 2 bending test method. Commonly used standard inspection methods are GB/T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ14019, DIN50111, and the like. The inspection items for evaluating the performance of angle steel are mainly tensile test and bending test. Indicators include yield point, tensile strength, elongation and bend qualification.

   The above is some of the main characteristics of angle steel, JUNNAN STEEL is introduced to everyone here, I hope to help everyone!
