Explanation:
For wide flange sections, the preferred ASTM material specification is ASTM A992. This standard refers to high-strength, low-alloy structural steel products, used for framing and architectural applications. The ASTM A992 offers better mechanical properties than the ASTM A36, providing higher yield strength and toughness. It is an important standard widely used in the construction industry, especially for steel bridge construction and buildings.
