The minimum size and gauge of metal plates specified must meet what ASTM standard?

ASTM A500
ASTM A653
ASTM A36
ASTM A572

The correct answer is: ASTM A653

The correct answer is B, ASTM A653. This standard pertains specifically to the specification of steel sheet products that are hot-dip galvanized after fabrication. It is particularly relevant when discussing metal plates used in construction, especially in coastal and floodplain environments where corrosion resistance is crucial due to exposure to moist or saline conditions. The standard outlines the requirements for the material's mechanical properties, coating weight, and surface condition, ensuring that the metal plates can withstand harsh environmental factors. The other options, while related to metal and construction materials, do not specifically address the minimum size and gauge requirements for metal plates as effectively as ASTM A653. ASTM A500 is related to cold-formed welded and seamless structural tubing, ASTM A36 specifies carbon structural steel shapes, plates, and bars for use in construction, and ASTM A572 covers high-strength, low-alloy columbium-vanadium structural steel. Therefore, they are not as suitable for the specific needs of metal plates discussed in the question regarding corrosion and other construction-specific requirements in flood-prone areas.
