Leaf- & Parabolic Springs

Spring Manufacturer since 1878

To the naked eye, most leaf springs look more or less the same. It is only when you study the materials from which they are made and the production process used in their manufacture, that the difference becomes apparent.

Weweler-Colaert exchanges technological knowledge and experience with some of the major technology institutes. Thanks to the partnership between Weweler-Colaert, the research center WTCM and the steel manufacturers, we have been able to develop new process parameters.

The use of new alloys in high-quality steel, a "Free Bending Hardening" method (FBH), combined with high stress shot peening brought our products to one of the highest levels of endurance.
