Grade 36 refers to a specific classification of steel, particularly in the context of structural and construction materials. It indicates a yield strength of 36,000 psi (pounds per square inch), which means the steel can withstand significant stress before deforming. This grade is commonly used in various construction applications, including beams, columns, and other structural components. In the United States, Grade 36 steel is often associated with the American Institute of Steel Construction (AISC) standards. It is widely utilized in building frameworks and bridges due to its balance of strength and ductility, making it a reliable choice for engineers and architects in their designs.
