Company Profile

Since 1896, Duer/Carolina Coil has met the most exacting   requirements and needs of customers in every line of manufacturing. Born in the steel belt of western Pennsylvania, Duer Spring and Manufacturing began by fabricating heavy-duty springs for the rail and mining industries. More than 120 years later, we remain a privately held company, serving customers in over 15 different markets and in more than 20 countries. Our roots are firmly planted in our commitment to skilled craftsmanship and purpose-driven work. Duer/Carolina Coil combines the wisdom earned from 120 years as a leader in the coil spring industry with the spirit of enterprise typically seen in a startup. This blend of old-world craftsmanship and new-age innovation is at the heart of most of the world’s enduring brands.
