Special
Strip Steel

Strip Steel for Power Springs
Power Springs are used in a wide variety of applications. Examples include - scales, automated door openers, hose and tooling retractors. The constant uncoiling and recoiling is the reason for good, clean round edges and a clean surface finish. Optimization of these characteristics enhances the fatigue properties of the spring. Uniform material hardness and tight geometric tolerances are required for constant torque.

Geometric tolerances and uniformity of hardness are also important for the actual spring manufacturing process. The recoil springs manufactured from this material are produced on high-speed automated equipment.

Flat Spring Steel
The number of end uses for this "stock" material is virtually unlimited. Much of the product is sold to Service Centers who serve an almost infinite number of smaller end users for a number of applications. High-volume examples include flat springs and blanked parts and shim stock.
A large volume of product also goes straight to stamping houses, again for a large variety of blanked parts, washers and blades.
