If sheet metal is 3/16 inch thick, what is it classified as?

• A. Sheet
• B. Plate
• C. Bar
• D. Wire

Answer: (B)

Thickness is the key factor in naming flat metal as sheet or plate. In welding and fabrication, the usual rule is that material up to 1/8 inch thick is sheet, and anything thicker is plate. A thickness of 3/16 inch is 0.1875 inch, which is larger than 1/8 inch, so it fits the definition of plate. The other terms refer to form rather than thickness: bar is a solid elongated piece with a uniform cross-section, and wire is a slender, small-diameter strand.
