Final answer:
The preferred ASTM material specification for steel angles is ASTM A36, which is commonly used for construction and architectural purposes.
Explanation:
The preferred ASTM material specification for steel angles is ASTM A36. This specification outlines the characteristics of carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. ASTM A36 is known for its good welding properties and is commonly used in construction and architectural applications.
Different ASTM specifications cater to various material properties and applications: ASTM A992 is typically used for structural steel beams, ASTM A500 is for cold-formed welded and seamless carbon steel structural tubing, and ASTM A514 is a specification for high-strength, quenched and tempered alloy steel plate, suitable for welding.
