on Structural Steel
    
    Structural steel is a type of steel used for building construction and other supporting structures. It is composed of two main types of steel: carbon steel, which is produced from iron ore and other minerals, and wrought iron, which is produced from recycled scrap metal and other materials. Structural steel has a high tensile strength and is one of the most malleable materials used in construction and engineering.
    
    Structural steel is used in a variety of applications, ranging from commercial and residential buildings, to bridges and other infrastructure projects. Most structural steel products are designed to meet specific codes and safety requirements, and are designed to last for lifetimes. The design of a structure depends on the desired loads, resistance, and deflections that must be achieved and the material used.
    
    When ordering structural steel, there are typically two design parameters to be considered. The first is the yield strength, which is a measure of how much force the steel can withstand before it begins to deform or break. The second design parameter is the thickness, which determines how much material is needed and how easily the steel will bend or flex. The higher the yield strength, the thicker and stronger the steel, meaning that it is better for heavier and potentially more dangerous structures.
    
    The most common type of structural steel is the mild steel, which comes in grades A36 and A572. Mild steel is often used in residential and low-load applications, due to its low ductility and malleability. Mild steel has a yield strength of 36,000 psi (250,000 kPa), which means that it can not only withstand high loads, but also flex and bend to some degree. However, mild steel is not suitable for more complex structures where heavy loads are constantly applied.
    
    High-strength steel, including A514, A588, and A852 grades, offers a higher yield strength, typically ranging from 50,000 to 100,000 psi (340,000-690,000 kPa). It is also more easily welded and fabricated than mild steel, making it a versatile choice for building and engineering. High-strength steel is typically used in taller and heavier structures, where significantly more resistance to loads is required.
    
    No matter the type of grade of structural steel, it is a light material that is an affordable and durable choice for many structural applications. Its malleability and strength properties make it perfect for a variety of projects. Its versatility and cost-effectiveness make it an invaluable choice for architects and engineers alike.
