Metal Spring FAQs … Answered.

We use the best metal for your project. Whenever possible, we source raw materials that are made in America. We form standard springs and specialty springs made from stainless steel, copper wire, galvanized wire, Inconel, steel alloys, and more.

We sure can! Read more about the benefits of alloy wire springs here!

We make springs for just about any industry you can think of. We’ve made springs for fast food automation and leading restaurant equipment suppliers. We’ve manufactured heavy-duty springs for residential and industrial garage doors and commercial overhead doors. We produce springs for attic ladders. We’ve put the spring in many a trampoline. We’ve made high-tensile springs for the agricultural industry. You name it, we spring it.

Yes we do!

Although Tennessee Spring and Metal is headquartered just outside of Music City (that’s Nashville, y’all), music wire isn’t what you string your guitar with. It’s a high-carbon steel alloy that’s cold drawn and offers uniform tensile strength. It’s great for high-stress applications that require a super durable spring.

Tensile strength refers to the maximum amount of load (stress) that a material (in our material world, we’re talking about metal) can handle until it fails.

It’s the quintessential spring that pushes back. Check out our blog to learn more about the different types of compression springs we manufacture.

An extension spring is the spring that sports hooks, eyes and loops that attach to a connecting part. It’s the spring that pulls everything together.

A torsion spring works by doing the twist! Torsion springs are flexible springs that twist along the axis. Learn more about metal torsion spring manufacturing here.

Whatever you need them to be! Wireforms are custom wire shapes that bend in different directions. Think hooks, clips, pins, and clamps. Clear as mud? Learn more about wire form manufacturing.

Custom springs are made to specific load and dimensional tolerances and may be coated for additional performance benefits. Utility springs are better suited for low-cycle applications.

Although we’re committed to using the best materials available, even our springs may, indeed, fail from time to time. Some common reasons springs (or humans, for that matter) may snap include excessive stress, excessive cycling, exceeding recommended temperature limits, and exposure to corrosive elements.

Also known as spring constant, the spring rate is the amount of weight needed to compress a spring by one inch. It’s typically expressed in pounds per inch or Newtons per millimeter.

Well, it depends. All springs are different and extension capabilities change depending on the material, coating, number of active coils, the ratio of outside diameter to the wire diameter, and more.

See above.
