Helical Compression Springs are the most common type of springs manufactured. They are most commonly made from round wire holding a constant pitch. Other types of compressions springs are variable pitch, hourglass, conical, and barrel compression springs. The ends of compression springs can be finished in several ways such as left open, open and ground, closed, or closed and ground. The two most common types are closed and ground and closed ends. Grinding the ends of the spring will allow for the spring to stand upright on a flat surface.
