Manufacture Your Seats With Spring Wire From Bekaert

Spring wire is a critical material for creating springs, which play a significant role in many parts of an automobile. Compression springs absorb energy upon compression and release it at decompression, making them vital to safety and function.

A common location for sinuous springs (aka: “Zig Zag springs”) is the car seat. Automotive seat spring wire needs to support the weight of the driver or passenger and make the area comfortable for sitting. When a driver rides over rugged terrain, sinuous springs will absorb the force and ensure a smooth ride. 

Power springs are also critical for seat reclining mechanisms. Discontinuous recliners use a lever release configuration and power springs push the seat forward when unlatched. Continuous recliners use wrap springs with start/stop functionality.

These springs need to have specific sizes and strengths for proper energy absorption. At Bekaert, we create our seat spring wire according to your specifications. We provide solutions for manual and electric-powered recliners, and with our established history working with spring manufacturers, you can trust our expertise.

For discontinuous recliners and continuous recliners, we use flat or rectangular spring wires that are hardened and tempered or hard-rolled.

Bekaert's Advantages for Automotive Spring Wire

Bekaert spring wire offers superior durability for your car seat springs. We can create a broad range of sizes and tensile strengths to support seats, doors, window regulators and more. Our spring wires also have excellent fatigue properties to ensure they last as vehicles age.

We adapt the carbon steel to your application with different development processes, including:

  • Induction hardening
  • Annealing
  • Hot rolling
  • Oil tempering 

We work side by side with your engineering team to develop your spring wires to your exact specifications. With this cooperative development process, you get the parts you're looking for every time.

Flexible Delivery For Your Schedule

Our turnkey approach carries through our development process all the way to delivery. Your delivery specifications will affect how well your finished seat spring wire integrates into your manufacturing line. 

We can ship your auto spring wire to you in spools, bar lengths or coils based on your needs. Our advanced technologies also allow us to cut to length if requested. We will find the best option for you and ship your products as soon as possible to keep you on schedule.

Precision Processes

Bekaert applies advanced processes to create precision final products. With our skills in wire drawing, cold-rolling, thermal treatment and coating procedures, we can develop spring wire that performs to your project standards.

Our team consists of highly trained engineers and metallurgists who specialize in these processes for results you can trust. While these precision processes offer accurate final products, they can also be more cost-effective than other methods and reduce the amount of material required. These factors help us support our sustainability mission while cutting costs for our clients. 

Customized Solutions

Steel spring wire may seem like a simple profile, but your applications will require specific measurements and properties. In addition to these factors, you'll need to consider the shape and edges of your wire. With our advanced machinery, we can form various shapes and edges to create the ideal performance for your spring wire. 

We can handle natural edge flat shapes, sharp edge squares and rectangles, half ovals and D-shapes, and trapezoids and triangles. If you're unsure what type of shape or edge might benefit your application, our experts can discuss your options and guide you to the best choice.
