Custom Springs

Sterling Spring, LLC is dedicated to becoming the spring supplier of choice through our customer-focused approach to product quality, open communication, technical service and on-time delivery. Through Sterling's commitment to our employees and investment in the latest spring manufacturing technology, we have expanded our capabilities beyond the typical compression, extension and torsion spring product mix. We think outside of the box and get excited to work on unique designs that are outside of the industry standard.
Compression springs lay at the foundation of Sterling Spring's history and with the introduction of CNC technology we have been able to reduce our setup times, improve our ability to meet tight tolerances and increase the versatility of spring shapes and sizes made directly off our machinery. We have the ability to make cylindrical, conical, barrel and magazine compression springs that can be manufactured with closed or open ends with our in-house grinding department prepared to meet all of your spring- end grinding needs. We are equipped to run wire sizes ranging from .003" to over a half an inch in diameter with outside diameter production capabilities that exceed five inches and have no boundaries on the length of your spring.
