SUPLEX is a leading manufacturer and supplier of coil springs, leaf springs, running springs and complete chassis suspensions. With more than 5,000 different applications, we have a wide range of products and services. SUPLEX coil springs are made from high quality spring steel, silicone chrome or vanadium spring steel. Using a spring tester, a data sheet is established with all parameters for all new springs to be developed. A prototype is created based on these parameters which must go through some tests, as metallographic examinations, mechanical material tests and durability tests. SUPLEX springs are blasted to compact the surface and extend longevity. SUPLEX goes even further and subjects the spring to a stress / exposure treatment during assembly. The zinc phosphate coating prevents corrosion of the spring steel.
