What type of plate is recommended for an 8"-13" penetration in steel decking?

• A. .045 inch plate
• B. .057 inch plate
• C. .065 inch plate
• D. .075 inch plate

Answer: (B)

When determining the appropriate plate thickness for anchoring into steel decking with an 8"-13" penetration, one must consider the load-bearing capacity and structural integrity required for the specific application. A plate thickness of .057 inch is generally recommended for this range of penetration due to several factors. First, the .057 inch plate strikes an effective balance between strength and weight. For penetrations in the specified range, this thickness can adequately support the tension and shear forces that might be encountered during normal use and under potential load conditions. The structural design codes often suggest using this thickness to ensure reliability while maintaining the necessary structural performance. Moreover, thicker plates such as .065 inch or .075 inch could be unnecessarily heavy and more challenging to work with, potentially leading to over-engineering for applications that do not require such robustness. The .045 inch plate, while lighter, may not provide sufficient strength and durability for the stresses associated with a penetration in this range. Overall, the .057 inch plate is deemed suitable, as it meets the structural requirements without excessive weight, which ensures ease of installation and efficiency in construction without compromising safety or performance.
