A572 is one of the highest value structural steel grades. Why? Because it provides an ideal combination of high strength, high notch toughness, good ductility, and good weldability.
It is a high-strength low alloy (HSLA) structural steel with five different grades. A572 grade 50 shows a yield strength of 50,000 psi and an ultimate tensile strength of over 65,000 psi. It is used across industries but is frequently seen in general building construction, the transportation industry, and the architecture industry.
A572-50 Beams provide improved strength when compared to their weight. As a result, this product grade is quickly replacing other hot rolled structural steel product grades as the de facto steel beam. Both S and W A572-50 beams can be black, galvanized, or primed.
A572-50 Channels are also widely seen in general building construction for the same reason-they provide greater strengths at less weight than other structural steel channel product grades. Both Structural Channels and MC Channels will have a minimum depth of 3".
A572-50 Bar Angles, which can also be referred to as angle irons, steel angles, L-brackets, steel sections, or angle sections, are a hot rolled HSLA product. Malleability is one of the key features of bar angles, as they are often applied for reinforcement and building fixtures to fortify corners and general reinforcement for things like bridges and archways. All bar angles have an L-shaped cross section, and while a 90° angle is most common, they can be designed to customer specification with equal or unequal leg lengths.
