Which ASTM standard governs wide-flange shapes (W-shapes) used in structural steel?

Explanation:
The key point here is that wide-flange structural shapes are defined by a standard that specifically covers structural shapes used in building construction. ASTM A992 sets the requirements for these shapes, including their dimensions, mechanical properties (such as a typical 50 ksi minimum yield strength for W-shapes), and tolerances. This makes A992 the go-to standard for W-shapes in framing and ensures consistency across fabrication and design. The other standards apply to different products—pipe (A53) and hollow structural sections (A500)—and do not govern W-shape properties. So A992 is the correct governing standard for wide-flange shapes.
