Torsion Springs

Torsion springsTorsion springs react to applied rotational force, either providing ‘torque’, or using stored rotational energy when the spring is set. The rotation force used should always allow the spring to decrease in diameter and increase in body length.

Marsh Springs has banks of machinery, including the latest CNC equipment, for torsion spring manufacture. We supply torsion springs for garage doors, window furnishings, agricultural equipment, and locks and latches to name a few.
