RCS is the Leader in Titanium Spring Manufacturing

RCS has designed, manufactured, and tested titanium springs for demanding aerospace applications for over 15 years. We are now bringing our design and manufacturing expertise to new markets where performance counts.

RCS engineers design springs specifically for demanding applications, not around the production ease or common material sizes as with most mass-produced steel springs. Consequently, the wire size, number of coils, and spring lengths are the optimal dimensions for the application. This optimization results in a custom designed spring that is as light as possible while providing the strength and durability demanded by the application.

RCS offers complete engineering assistance to help our customers. Advanced materials, computer modeling, state of the art equipment and extensive experience are the foundations of a successful spring design. You don’t have to know a lot about springs to work with us, that’s our job. We’ll help you make your product perform better.
