Metal treatments such as heat treating, tumbling and shot peening along with other processing treatments all improve the life of springs.

Coatings are an example of treatments that make springs withstand corrosion and abrasion. Electrodeposition coating for corrosion resistance is available in black. Electroplated coatings are offered in clear, yellow, black and various other colors. Passivation cleans stainless steel and improves tarnish resistance. Other coatings available are nickel/tin, chrome, anodizing, cadmium plating, and black oxide, both painted and powder.

Compression spring ends can be:

Extension spring ends as well as torsion spring ends are offered in standard and special designs.
