indicating a spring designed for heavy-duty use and long-term durability. (In some regions, this might
be referred to as an 8-gauge wire).
Round: Describes the cross-section of the wire. Round wire is the standard and most common type for
these springs.
ZigZag / Sinuous Spring: The characteristic wavy shape that provides the spring action and support.

applied.
