Introduction structural steel (SAE 81B45)
Structural steel is a steel that conforms to a specific strength and formability grade. The formability is expressed as the elongation at the end of the tensile test. Structural steel is generally used for bearing and other purposes. In these uses, the strength of steel is an important design standard.
Most steels used throughout Europe are specified to comply with the European standard EN 10025. However, many national standards also remain in force.
Application(SAE 81B45)
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.
