Duer/Carolina Coil About

Our roots go back to 1896. Born in the steel belt of western Pennsylvania, Duer Spring and Manufacturing began by fabricating heavy-duty springs for the rail and mining industries. A little more than a hundred years later, Duer/Carolina Coil is headquartered in a state-of-the-art 130,000 square foot facility located on the dynamic I-85 corridor outside of Greenville South Carolina.

Here, we bring together generations of craftsmanship with a team of the industry’s brightest engineering minds.

So what sets us apart?

Each employee of Duer/Carolina Coil understands that every spring we make is used by a customer that’s pressed for time, quality and a desire to succeed. Everything we do is driven by this notion of partnership.

It means we buy from only the most reputable steel suppliers. It means we invest continuously in our people, processes and machinery to be more efficient in our plant. It means we never compromise on quality. And it means integrity in our pricing.
