Focusing on quality, Duer/Carolina Coil didn't become a top-of-the-line spring manufacturer by accident. We produce grade-A springs for our valued customers. Since 1896, we have been producing extension springs, compression springs and torsion springs for various industries.
A coil spring is an elastic element made of metal or heavy plastic in the form of curls or ringlets of round wire or cord that is wrapped around a cylinder. The winding of a coil spring can be loose or tight in a helical shape depending on the application for which it is made...
Coil springs called compression springs can store mechanical energy when they are compressed. These open-coiled, helical springs provide resistance to compressive loading. When these springs are...
Extension springs are helical wound springs that are so closely coiled together to create initial tension in the coils. This initial tension creates resistance against the force applied to its ends for extension. The initial tension helps determine how closely and...
