Leaf Springs

The springs are further treated and processed to achieve an optimal strength and toughness ratio of the material, ensuring high operational stability of shape. The most advanced surface treatment technologies are used to ensure long fatigue life. Hot forming technology enables to produce and supply springs in a wide range of sizes and accuracy.

Available production equipment provides the spring user with a significant degree of shape choice, especially spring fixing elements.
